Assessment

Business

An activity to analyze quality or effectiveness and consider available options.

The Assessment is a generic class that regroups different types of more specific assessments. An example of Assessment is a SWOT assessment that identifies the Strengths, Weaknesses, Opportunities and Threats of a specified proposal. Another example is a Gap Analysis that formalizes the difference between the current situation and the state to reach due to certain requirements. An Assessment can use various objects as inputs, whether they are the main objects that the Assessment is about or auxiliary information objects that help the accomplishment of the assessment.

Business Case

Business

A proposal for a body of work that will deliver outputs designed to achieve outcomes. A Business Case will provide the reasoning for initiating a new Statistical Program Design for a Statistical Program, as well as the details of the change proposed.

A Business Case is produced as a result of a detailed consideration of a Change Definition. It sets out a plan for how the change described by the Change Definition can be achieved. A Business Case usually comprises various evaluations, for example a SWOT assessment, or Gap Analyses for the different solutions that are considered for satisfying the Statistical Need. The Business Case will also specify the stakeholders that are impacted by the Statistical Need or by the different solutions that are required to implement it.

 

Business Function

Production

Something an enterprise does, or needs to do, in order to achieve its objectives.

A Business Function delivers added value from a business point of view. It is delivered by bringing together people, processes and technology (resources), for a specific business purpose.

Business Functions answer in a generic sense "What business purpose does this Process Step Design serve?" Through identifying the Business Function associated with each Process Step Design it becomes easier in for someone in future with an equivalent business need to identify Process Step Designs that they might reuse (in whole or in part).
A Business Function may be defined directly with descriptive text and/or through reference to an existing catalogue of Business Functions. The phases and sub processes defined within GSBPM can be used as an internationally agreed basis for cataloguing high level Business Functions. A catalogue might also include Business Functions defined at a lower level than "sub process". For example, "Identify and address outliers" might be catalogued as a lower level Business Function with the "Review, validate and edit" function (5.3) defined within GSBPM.

 

Business Service

Production

A defined interface for accessing business capabilities (an ability that an organization possesses, typically expressed in general and high level terms and requiring a combination of organization, people, processes and technology to achieve).

A Business Service may provide one means of accessing a particular Business Function. Requesting a particular service through the defined interface may result in a business process (workflow) being executed.

The explicitly defined interface of a Business Service can be seen as representing a "service contract". If particular inputs are provided then the service will deliver particular outputs in compliance within specific parameters (for example, within a particular period of time).

In the case of GSIM, a Business Service typically implements a particular Process Method to perform a particular Business Function.

Note: The interface of a Business Service is not necessarily IT based. For example, a typical postal service will have a number of service interfaces: - Public letter box for posting letters - Counter at post office for interacting with postal workers

Change Definition

Business

A structured, well-defined specification for a proposed change.

A related object - the Statistical Need - is a change expression as it has been received by an organization. A Statistical Need is a raw expression of a proposed change, and is not necessarily well-defined. A Change Definition is created when a Statistical Need is analyzed by an organization, and expresses the raw need in well-defined, structured terms.

A Change Definition does not assess the feasibility of the change or propose solutions to deliver the change - this role is satisfied by the Business Case object. The precise structure or organization of a Change Definition can be further specified by rules or standards local to a given organization.

Once a Statistical Need has been received, the first step is to do the conceptual work to establish what it is we are trying to measure. The final output of this conceptual work is the Change Definition.

The next step is to assess how we are going to make the measurements - to design a solution and put forward a proposal for a body of work that will deliver on the requirements of the original Statistical Need. The Change Definition is an input to this Process Step and the final Business Case is an output. Depending on the needs of individual agencies a Change Definition may be created before or after a Business Case has been created, or even created to a basic extent before the Business Case development and further developed after a Business Case has been approved and a decision made to proceed with the change.

Concept

Concepts

Unit of thought differentiated by characteristics

ISO 1087-1 defines Concept as a "unit of knowledge created by a unique combination of characteristics". First, the term knowledge is poorly defined, and the word thought seems to capture the idea more cleanly. Second, different systems may try to capture the same thought but depend on different characteristics (i.e., attributes). For instance, typical demographic surveys care about age, sex, income, ethnicity, and education of persons. However, persons in a justice survey are either criminals or victims.

Data Channel

Business

A means of exchanging data.

A Data Channel is an abstract object that describes the means for communicating with Data Resource(s). The Data Channel identifies the Instrument Implementation, Mode, and Data Resource that are to be used in a process. In some cases the Data Channel that is used by the Data Provider to send its responses could be different that the one used by the statistical office or organization to request information; the statistical office may put electronic formats that can be downloaded by the Data Provider and once answered returned by traditional mail. Two specialized objects are used to implement this abstract object: Channel Design Specification used at design time and Channel Activity Specification used at run time.

 

Data Consumer

Base

An organization that uses data or metadata as input for further processing.

 

 

Data Flow

Structures

The Data Flow represents both the availability of data over time and the availability of sub sets of the possible data that could be made available according to a Data Structure.

There may be many data sets structured according to a Data Structure, perhaps made available at a pre-defined frequency (for example, monthly).

There can be many Data Flows that share the same Data Structure: for instance data for National Accounts may be compartmentalized into a number of Data Flows for organizational purposes or for data discovery purposes (there can be different Data Flows for different sub sets of National Accounts where each sub set is structured by the same Data Structure).

 

Data Location

Structures

Example for Unit Data: (1212123, 43) could be the age in years on the 1st of January 2012 of a person (Unit) with the social security number 1212123. The social security number is an identifying variable for the person whereas the age, in this example, is a variable measured on the 1st of January 2012.

 

Data Provider

Base

Examples of Data Sets could be observation registers, time series, longitudinal data, survey data, rectangular data sets, event-history data, tables, data tables, cubes, registers, hypercubes, and matrixes. A broader term for Data Set could be data. A narrower term for Data Set could be data element, data record, cell, field

database, data file, file, table

Data Structure

Structures

Defines the structure of an organized collection of data (Data Set).

The structure is described using Data Structure Components that can be either Attribute Components, Identifier Components or Measure Components. Examples for unit data include social security number, country of residence, age, citizenship, country of birth, where the social security number and the country of residence are both identifying components (Unit Identifier Component) and the others are measured variables obtained directly or indirectly from the person (Unit) and are Unit Measure Components.

 

Data Structure Component

Structures

The identification of the Represented Variable used in the context of a Data Structure.

A Data Structure Component can be an Attribute Component, Measure Component or an Identifier Component.

Example of Attribute Component: The publication status of an observation such as provisional, revised.

Example of Measure Component: age and height of a person in a Unit Data Set or number of citizens and number of households in a country in a Data Set for multiple countries (Dimensional Data Set).

Example of Identifier Component: The personal identification number of a Swedish citizen for unit data or the name of a country in the European Union for dimensional data.

Dimensional Data Point

Structures

A placeholder or cell in a Dimensional Data Set determined by the crossing of (all) the values for the Identifier Components to contain the value (Datum) for an Instance Variable (defined by a Measure Component) with respect to a given Unit.

A Dimensional Data Point is uniquely identified by the combination of exactly one value for each of the dimensions (Dimensional Identifier Component) and one measure (Dimensional Measure Component). There may be multiple values for the same Dimensional Data Point that is for the same combination of Dimension values and the same measure. The different values represent different versions of the data in the Data Point. Values are only distinguished on the basis of quality, date/time of measurement or calculation, status, etc. This is handled through the mechanisms provided by the Datum information object.

Dissemination Service

Structures

The mechanism for delivering, and possibly creating, structured content dynamically in response to a consumer request and in accordance with defined parameters as provided by that consumer.

A Dissemination Service will deliver a Representation created by a process that it invokes. The inputs into the Dissemination Service determine and feed the process that is to be invoked.

A Dissemination Service retrieves the information to be structured and delivered through an Information Resource. As part of the service execution, the consumer may be given a chance to browse or search through the collection of information available from the Information Resource exposed by the Dissemination Service. Based on the results, the consumer can than refine the Output Specification as (further) input to the Dissemination Service to complete the process of creating and delivering the information required in the form of a Representation to the consumer.

Example:

1. SDMX SOAP Data Web Services: The query XML message provides the Service with data selection and the specification of the preferred format (e.g. Generic format or Structured format, time series or cross-sectional). Based on this input the Service will retrieve a Data Set from the Data Resource and invoke a process that will format the data as an SDMX data message.
2. A manual service such as a response to a telephone request where the person answering the call based on the caller's request would mail a PDF (which might either be a Product or dynamically created from another source).

Environment Change

Business

A requirement for change (type of Statistical Need) that originates from a change in the operating environment of the statistical activity.

An Environment Change reflects variations in the context of execution of the Statistical Activity that create a need for a modification in the way that this activity is conducted. Environment Changes can be of different origins and also take different forms. They can result from a precise event (budget cut, new legislation enforced) or from a progressive process (technical or methodological progress, application or tool obsolescence). Other examples of Environment Changes include the availability of a new Data Resource, the opportunity for new collaboration between agencies, etc.

Environment Change objects may be structured in very diverse ways, but an object will usually group text material describing the type of change that has occurred and created the need for change. This allows the statistical organization to document precisely the (possibly multiple) changes in environment that have led to the Statistical Need.

 

Evaluation Assessment

Business

A type of Assessment that evaluates the process outputs of a statistical activity based on a formalized methodological framework.

The evaluation can be done in regard to various characteristics of the output, for example its quality, the efficiency of the production process, its conformance to a set of requirements, etc. The result of an Evaluation Assessment can lead to the creation of a Statistical Need: in this case, the Statistical Need will reference the Evaluation Assessment for traceability and documentary purposes.

Output Specification

Structures

Contains the specifications for the dynamic creation and delivery of a Representation by a Dissemination Service.

An Output Specification is a specialization of Parameter Input. It is in fact a request for the dynamic creation and delivery of a Representation. It contains references to the information (e.g. a Data Set, a Data Structure, a Code List, a publication plan) desired with specifications concerning selections, (technical) form and/or method of delivery.

The references to the information come from the collection of information sources provided by the Information Resource that is exposed by the Dissemination Service. The consumer may select any (combination) of those information sources by including the references in the Output Specification.
Note that the Output Specification may be "soft" or "broad" in that it may identify groups of internal information objects rather than individual ones. For instance, all Data Sets within a certain (sub) category or theme. This may lead to multiple Representations being delivered.

As part of the Output Specification, the consumer may be given the option to select one of a number of possible formats for the Representation (e.g. SDMX, CSV, JSON or PDF) or to select one of a number of possible methods for delivery (web service response, email, FTP, mail delivery, etc.) The Dissemination Service may be used to request future deliveries of Representations for information that is not yet available. This results in a subscription, where the specification of the Representations to be delivered in future is given in the Output Specification.

Parameter Input

Production

Inputs used to specify which configuration should be used for a specific Process Step which has been designed to be configurable.

Parameter Inputs may be provided where Rules and/or Business Service interfaces associated with a particular Process Step have been designed to be configurable based on inputs passed in to the Process Step.

 

Population

Concepts

The total membership of a defined class of people, objects or events

Population has a number of subtypes. Here are 3 examples –
1. US adult persons
2. US computer companies
3. Universities in the US

 

Process

Production

A nominated set of Process Step Designs, and associated Process Controls (flow), which have been highlighted for possible reuse.

In a particular statistical business process, some Process Steps may be unique to that business process while others may be applicable to other business processes. A Process can be seen as a reusable template. It is a means to accelerate design processes and to achieve sharing and reuse of design patterns which have approved effective. Reuse of process patterns can also lead to reuse of relevant Business Services and business Rules.
By deciding to reuse a Process, a designer is actually reusing the "pattern" of Process Step Designs and Process Controls associated with that Process. They will receive a new instance of the Process Step Designs and Process Controls. If they then tailor their "instance" of the Process Step Designs and Process Controls to better meet their needs they will not change the definition of the reusable Process.

 

Process Control

Production

A decision point which determines the flow between Process Steps.

The typical use of Process Control is to determine what happens next after a Process Step Design is executed. The possible paths, and the decision criteria, associated with a Process Control are specified as part of designing a production process. There is typically a very close relationship between the design of Process Steps and the design of Process Controls.

It is possible to define a Process Control where the next Process Step that will be executed is a fixed value rather than a "choice" between two or more possibilities. Where such a design would be appropriate, this feature allows, for example, initiation of a Process Step representing the GSBPM Process Phase (5) to always lead to initiation of GSBPM sub-process Integrate Data (5.1) as the next step.

This allows a process designer to divide a business process into logical steps (for example, where each step performs a specific Business Function) even if these Process Steps will always follow each other in the same order. In all cases, the Process Control defines and manages the flow between Process Steps, even where the flow is "trivial". Process Step Design is left to focus entirely on the design of the Process Step itself, not sequencing between steps.

 

Process Input

Production

Any instance of an information object which is supplied to a process step at the time its execution is initiated.

Process Input has three subtypes: Process Support Input, Parameter Input and Transformable Input, to be able to identify the range of roles that the Process Inputs perform in the course of a Process Step. A Process Input may be provided to a Process Step to: - "add value" to that input by producing an output which represents a "transformed" version of the input.

  • control (for example, as a parameter) or influence the behavior of the Process Step.
  • be used by the Process Step as either an input or a guide.

    Note: The same instance of an information object may perform different roles in regard to different Process Steps.

 

Process Input Specification

Production

A record of the types of inputs required for a Process Step Design

The Process Input Specification enumerates the Process Inputs required at the time a Process Step Design is executed. For example, if five different Process Inputs are required at the time, the Process Input Specification will describe each of the five inputs. For each required Process Input the Process Input Specification will record:

1. the type of Process Input (Parameter Input, Process Support Input or Transformable Input); and 2. the type of information object (based on GSIM) which will be used as the Process Input (Example types might be a Dimensional Data Set or a Classification).

The Process Input to be provided at the time of Process Step execution will then be a specific instance of the type of information object specified by the Process Input Specification. For example, if a Process Input Specification requires a Dimensional Data Set then the corresponding Process Input provided at the time of Process Step execution will be a particular Dimensional Data Set.

 

Process Method

Production

A specification of the technique which will be used to perform the unit of work.

The technique specified by a Process Method is independent from any choice of technologies and/or other tools which will be used to apply that technique in a particular instance. The definition of the technique may, however, intrinsically require the application of specific Rules (for example, mathematical or logical formulas).

A Process Method describes a particular method for performing a Business Function. Similarly to the way in which Business Function documents the high level purpose of a process step ("what business purpose does this process step serve?"), Process Method documents the high level methodological "how" associated with the Process Step. Where a Process Step Design applies a method which is not specifically statistical in nature, however, this can still be recorded as the Process Method.

 

Process Metric

Production

A Process Output whose purpose is to measure and report some aspect of how the Process Step performed during execution.

A Process Metric is a sub-type of Process Output which records information about the execution of a Process Step. For example, how long it took to complete execution of the Process Step and what percentage of records in the Transformable Input was updated by the Process Step to produce the Transformed Output.

One purpose for a Process Metric may be to provide a quality measure related to the Transformed Output. For example, a Process Step with the Business Function of imputing missing values is likely to result, as its Transformed Output, in a Data Set where values that were missing previously have been imputed. Statistical quality measures, captured as Process Metrics for that Process Step may include a measure of how many records were imputed, and a measure of how much difference, statistically, the imputed values make to the dataset overall.
Another purpose for a Process Metric may be to measure an aspect of the Process Step which is not directly related to the Transformed Output it produced. For example, a Process Metric may record the time taken to complete the Process Step or other forms of resource utilization (for example, human and/or IT).

Often these two kinds of Process Metrics will be used in combination when seeking to, for example, monitor and tune a statistical business process so its statistical outputs achieve the highest level of quality possible based on the time, staff and/or IT resources that are available.

 

Process Output

Production

Any instance of an information object which is produced by a Process Step as a result of its execution.

Process Outputs are subtyped.

  • Transformed Output is the result which provides the "reason for existence" of the Process Step. If that output were no longer required then there would be no need for the Process Step in its current form. Typically a Transformed Output is either a Process Input to a subsequent Process Step or it represents the final product from a statistical business process.
  • A Process Metric records information about the execution of a Process Step. For example, how long it took to complete execution of the Process Step and what percentage of records in the Transformable Input was updated by the Process Step to produce the Transformed Output.

 

Process Output Specification

Production

Identifies the types of Process Outputs the associated Process Step Design will produce when it is executed.

The Process Output Specification enumerates the Process Outputs that will be generated at the time the associated Process Step Design is executed. For example, if five different Process Outputs will be generated at the time of Process Step execution the Process Output Specification will describe each of the five outputs. For each Process Output the Process Output Specification will record:

1. the type of Process Output (Process Metric or Transformed Output) 2. the type of GSIM information object which will be generated as the Process Output.

An example type might be a Dimensional Data Set. The Process Output generated at the time of Process Step execution will then be a specific instance of the type of information object specified by the Process Output Specification. For example, if a Process Output Specification refers to generation of a Dimensional Data Set then the corresponding Process Output generated at the time of Process Step execution will be a particular Dimensional Data Set. For each Process Step execution a different Dimensional Data Set will be generated.

 

Process Step

Production

One in a series of tasks which comprise a statistical business process

 A Process Step implements the Process Step Design specified in order to produce the outputs for which the process step was designed.

 

Process Step Design

Production

Defines how a Process Step will be performed. This includes specifying the Process Inputs to that work and the Process Outputs that will be produced.

A Process Step can be as big or small as the designer of a particular business process chooses. From a design perspective, one Process Step can contain "sub-steps", each of which is conceptualized as a (smaller) Process Step in its own right. Each of those "sub-steps" may contain "sub-steps" within them and so on indefinitely. It is a decision for the process designer to what extent to subdivide steps. At some level it will be appropriate to consider a Process Step to be a discrete task (unit of work) without warranting further subdivision. At that level the Process Step is designed to process particular Process Inputs, using a particular Business Service, to produce particular Process Outputs. The flow between a Process Step and any sub steps is managed via Process Control.

 

Process Step Execution Record

Production

A record of the execution of a Process Step. The record includes the actual Process Inputs to, and Process Outputs from, each Process Step. as well as the evaluation of each Process Control (which, in turn, determines the specific sequence of Process Steps performed during execution).

Each Process is an instance of executing a repeatable Process Step Design. At the time of Process Step Execution specific instances of input objects (for example, specific Data Sets, specific Variables) will be supplied.

Each instance of Process Step may produce unique results even though the Process Step Design remains constant. One reason is that specific instances of inputs are provided for each Process Step.

Even when the inputs remain the same, metrics such as the elapsed time to complete execution of process step may vary from execution to execution. For this reason, each Process Step Execution Record details of inputs and outputs for that instance of implementing the Process Step Design. It also records the outcome of Process Control evaluation at the end of the process step.

In this way it is possible to trace the flow of execution of a business process through all the process steps which were involved.

 

Process Support Input

Production

A form of Process Input that influences the work performed by the Process Step, and therefore influences its outcome.

Process Support Input is a sub-type of Process Input. Typical Process Support Inputs include metadata resources such as Classifications or structural information used in the processing of data.

Examples of Process Support Inputs could include - A Code List which will be used to check whether the Codes recorded in one dimension of a dataset are valid - An auxiliary Data Set which will influence imputation for, or editing of, a primary Data Set which has been submitted to the Process Step as the Transformable Input.

In these examples, which Code List to use, or which auxiliary Data Set to use, may be specified via a Parameter Input. The details of the Code List or the auxiliary Data Set are Process Support Inputs.

 

Product

Structures

Static package of objects that can be disseminated as a whole.

A Product is a static presentation of artefacts created by fixed processes. The artefacts may be representations of data, visualizations, explanation, interpretation etc. Example: Publications, press releases, articles, list of classifications, etc.

publication

Production Activity

Business

The set of executed processes and the actual resources required as inputs and produced as outputs in the production of data for a given Population for a particular reference period. It describes the process and resources required in the production of data in a Statistical Program.

These objects hold Statistical Activity information that relates specifically to data production. It inherits the relationships and attributes from the Statistical Activity type.

 

Production Design

Business

The specification of the resources required and processes used and description of relevant methodological information for a set of activities to process data about a given Population.

This object holds Statistical Program Design information that relates specifically to production - the act of taking data that have been collected and transforming them. It inherits the relationships and attributes from the Statistical Program Design type.

 

Provision Agreement

Structures

A service-level agreement, a legal mandate, the terms of a mutual agreement, a memorandum of understanding, or any other terms/conditions which affect the provision of data.

The Provision Agreement does not need to have any formal consent of the Data Provider. For instance data collection via web scraping may identify the Data Provider but requires no formal agreement. A web service that provides data to anyone that queries it also may not need any formal agreement (save that perhaps of implicit agreement under the terms of the web service). Nevertheless, in both these cases the data may be structured according to a Data Structure which is associated to the Data Flow.

A Provision Agreement represents the union of a specific Data Provider and a specific Data Flow for which the Data Provider supplies data. The location of the Data Sets that are available for this Provision Agreement are associated in the Data Location.

 

Publication Activity

Business

The mechanism for creating structured, static content in response to an internal trigger.

A Publication Activity is a specific type of Dissemination Activity. A Publication Activity is triggered by an internal need to create a new Product. This is most commonly based on knowledge about a general need of potential consumers or the objective to actively provide information to consumers. Examples are the writing, editing and approval of a press release, web article or publication.

A Publication Activity may make use of Dissemination Services to get the necessary input. A Publication Activity may interpret or transform (e.g. visualize) statistical data, but cannot do any statistical processing.

A Publication Activity produces a Product and makes this available to Dissemination Services (possibly through an Information Resource) for the actual dissemination.

Record Relationship

Structures

Describes relationships between Logical Records within a Unit Data Structure. It must have both a source Logical Record and a target Logical Record in order to define the relationship.

All relationships are defined in pairs. Hence multiple relationships may be needed to clarify all Record Relationships within a Unit Data Set e.g. household and person, household and dwelling etc.

Example: Relationship between person and household Logical Records within a Unit Data Set.

 

Representation

Structures

A "custom-built" artefact that has a consumable (human or machine) format. It is the output of a Dissemination Service. It is what is ultimately delivered to the consumer.

A Representation brings together various maintainable artefacts and their related artefacts. It is essentially the application of rules to an artefact (and possibly its related artefacts) which transform the object into a format fit for consumption. This consumption may be something that is understandable to a person or a machine.

Representation can be in different forms; e.g. tables, graphs, structured data files.
Examples:

  • A table of data. Based on a Data Set, the related Data Structure is used to label the column and row headings for the table. The Data Set is used to populate the cells in the table. Reference metadata is used to populate footnotes and cell notes on the table. Confidentiality rules are applied to the Data Set to suppress any disclosive cells.
  • A data file based on a standard (e.g. SDMX). - A PDF document describing a Classification.
  • Any structural metadata object expressed in a standard format (e.g. DDI 3.1 XML).
  • A list of Products or services (e.g. a product catalogue or a web services description language (WSDL) file).
  • A web page containing Classifications, descriptions of Variables, etc.

Represented Variable

Concepts

Here are 3 examples –
1. Sex variable which will be collected using
<m, male>,
<f, female>,
<o, other>

2. Number of Employees variable which will be collected using an Integer or Count of Individuals.

3. Endowment of Universities variable which will be collected using
<1, $0-$99,999>,
<2, $100,000-$999,999>,
<3, $1,000,000 and above>

 

Rule

Production

A specific mathematical or logical expression which can accept inputs and be evaluated based on those inputs.

There are many forms of Rules and their purpose, character and expression can vary greatly.
Evaluation Rules consist of computing an output which will result in a particular course of action. The logical Rules implemented by a Process Step and their implementations in executable form. A single Rule (at the conceptual level) may be expressed in different ways when using different notations and/or different software at the implementation level.

Rules can be "nested". In other words, a Rule can accept the outputs/evaluations from one or more other Rules as its inputs. This approach can be useful to achieve reuse of Rules.

A Rule can be used to generate new data (for example, determine values for a derived Variable) based on existing data. Rules can also be designed to apply "if then else" logic or "case" logic. Parameter Inputs can be included in the definition of a Rule and values provided for those parameters at the time the Rule is evaluated.

Statistical Activity

Business

The set of executed processes and the actual resources required as inputs and produced as outputs to investigate the characteristics of a given Population for a particular reference period. It may describe process and resources required to acquire (Acquisition Activity), produce (Production Activity), and disseminate (Dissemination Activity) data in a Statistical Program.

A Statistical Activity includes the run-time information used to actually execute a set of processes. Activities occur in the context of each Statistical Program Cycle and execute a particular Statistical Program Design.

 

Statistical Need

Business

A requirement, request or other notification that will be considered by an organization. A Statistical Need does not have necessarily have structure or format - it is a 'raw' need as received by the organization. A Statistical Need may be of a variety of types including Environmental Change or Information Request.

The Statistical Need is a proposed or imposed change as it has been received by an organization. A Statistical Need is a raw expression of a proposed change, and is not necessarily well-defined. A related object - Change Definition - is created when a Statistical Need is analyzed by an organization. Change Definition expresses the raw need in well-defined, structured terms.
Once a Statistical Need has been received, the first step is to do the conceptual work to establish what it is we are trying to measure. The final output of this conceptual work is the Change Definition.

In some cases, the Statistical Need can result from the Assessment of the quality, efficiency, etc. of an existing process.

 

Statistical Program

Business

A set of activities to investigate characteristics of a given Population. It describes the purpose and context of a set of Statistical Activities.

The Statistical Program is one of a family of objects that provide the environmental context in which a set of statistical activities is conducted. Statistical Program is the top level object that describes the purpose and objectives of a set of activities. Statistical Program will usually correspond to an ongoing activity such as a survey or output series. Some examples of Statistical Program are:

  • Labour Force Survey - Multipurpose Household Survey - National Accounts - Demography - Overseas Arrivals and Departures

    Related to the Statistical Program object there are Statistical Program Design and Statistical Program Cycle objects that hold the detailed information about the design and conduct of the Statistical Activity.

    In the case of the traditional approach, an organization has received a Statistical Need and produced a Change Definition and an approved Business Case. The Business Case will specify either a change to the design or methodology of an existing Statistical Program, which will result in a new Statistical Program Design; or a change to one or more existing Statistical Programs (for example, to add an additional objective to the Statistical Program); or result in a new Statistical Program being created.

 

Statistical Program Cycle

Business

A set of activities to investigate characteristics of a given Population for a particular reference period.

A Statistical Program Cycle documents the execution of an iteration of a Statistical Program according to the associated Statistical Program Design for a certain reference period. It identifies the activities that are undertaken as a part of the cycle and the specific resources required and processes used and description of relevant methodological information used in this cycle defined by the Statistical Program Design.

 

Statistical Program Design

Business

The specification of the resources required and processes used and description of relevant methodological information about the set of activities investigating characteristics of a given Population. Includes the Statistical Activities that are required to acquire (Acquisition Activity), produce (Production Activity), and disseminate (Dissemination Activity) data in a Statistical Program.

The Statistical Program Design is one of a family of objects that provide the operational context in which a set of statistical activities is conducted.

A simple example is where a Statistical Program relates to a single survey, for example, the Labour Force Survey. The Statistical Program will have a series of Statistical Program Design objects that describe the methodology and design used throughout the life of the survey. When a methodological change is made to the survey, a new Statistical Program Design is created to record the details of the new design.

Survey Instrument

Business

A specialized kind of Instrument used for the explicit purpose of gathering statistical data.

Survey Instrument is a tool used to gather information from a Data Resource. It can be applied in several ways using different formats and modes, for example, as paper forms in face-to-face interviews, as online self-administered interviews, as computer-assisted questionnaires in telephone interviews, as electronic templates downloaded from the web and returned via email. The Survey Instrument provides a generic description of the data collection form independent of the format and mode.

 

Survey Population

Concepts

Transformable Input

Production

A type of Process Input whose content goes into a Process Step and is changed in some way by the execution of that Process Step. Some or all of the content will be represented in the Transformed Output.

Transformable Input is a sub-type of Process Input. Producers of official statistics often conceptualize data (and sometimes metadata) flowing through the statistical business process, having statistical value added by each Process Step and being transformed along the way.

The concept of Transformable Input allows this notional flow of information through the production process to be traced, without confusing these inputs with other inputs - such as Parameter Inputs and Process Support Inputs that are controlling or influencing a particular Process Step but do not "flow through the business process" in the same sense. Typical Transformable Inputs are Data Sets and structural metadata (if changed by a process and needed to describe another output or as an object in their own right).

 

Transformed Output

Production

A Process Output (a result) which provides the "reason for existence" for the Process Step.

A Transformed Output is a sub-type of Process Output. Typically a Transformed Output is either a Process Input to a subsequent Process Step or it represents the final product from a statistical business process.

In many cases a Transformed Output may be readily identified as an updated ("value added") version of one or more Transformable Inputs supplied to the Process Step execution.

Note: If the output were no longer required then there would be no need for the Process Step in its current form.

Unit Data Point

Structures

A placeholder in a Unit Data Record to contain the value (Datum) for an Instance Variable with respect to a given Unit.

For example (1212123, 43) could be the age in years on the 1st of January 2012 of a person (Unit) with the social security number 1212123. The social security number is an identifying variable for the person whereas the age, in this example, is a variable measured on the 1st of January 2012. The value can be obtained directly from the Unit or indirectly via a process of some kind.

 

Unit Data Record

Structures

Contains the specific values (as a collection of Unit Data Points) related to a given Unit as defined in a Logical Record.

For example (1212123, 48, American, United Kingdom) specifies the age (48) in years on the 1st of January 2012 in years, the current citizenship (American), and the country of birth (United Kingdom) for a person with social security number 1212123.
