Business Function
Business
activities undertaken by a statistical organisation to achieve its objectives
A BusinessFunction 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 Business Service _or Process Step_ serve? (c.f. Business Process answers the question of How?). Through identifying the Business Function associated with each Business Service or Process Step, it increases the documentation of the use of the associated Business Services and Process Steps, to enable future reuse. 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 and validate function (5.3) defined within GSBPM.

Change Definition
Business
structured, well-defined specification for a proposed change
A related class - the Statistical Need - is a change expression as it has been received by an organisation. 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 analysed by an organisation, 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 class. The precise structure or organisation of a Change Definition can be further specified by rules or standards local to a given organisation. It also includes the specific Concepts to be measured and the Population that is under consideration. 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.

Core Input is a sub-type of Process Input. Producers of official statistics often conceptualise data (and sometimes metadata) flowing through the statistical Business Process, having statistical value added by each Process Step. The concept of Core 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 Core Inputs are Data Sets and structural metadata.

Process Control Design
Business
specification of the decision points required during the execution of a Business Process
The design of a Process Control typically takes place as part of the design of the process itself. This involves determining the conditional routing between the various sub-processes and services used by the executing process associated with the Process Control and specified by the Process Control Design. _It is possible to define a _Process Control where the next step in the_ 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 step in the 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 through re-use of a Business Service) even if these Process Steps will always follow each other in the same order. In all cases, the Process ControlDesign defines and the Process Control manages the flow between Process Steps, even where the flow is trivial. Process Design is left to focus entirely on the design of the process itself, not sequencing between steps.

specification of each Process Step and description of their arrangement in a Business Process needed to perform a Business Function
A Process Design is the design time specification of a Process Step that is performed as part of a run-time Business Service. A Process Step can be as big or small as the designer of a particular Business Service chooses. From a design perspective, one Process Step can contain sub-steps, each of which is conceptualised as a (smaller) Process Step in its own right. Each of those sub-steps may contain sub-steps within them and so on. 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 without warranting further subdivision. At that level the Process Step is designed to process particular Process Inputs, according to a particular Process Method, to produce particular Process Outputs. The flow between a Process Step and any sub steps is managed via Process Control.

Process Output summarising some aspect or property of the 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 Core Input was updated by the Process Step to produce the Core Output. One purpose for a Process Metric may be to provide a quality measure related to the Core Output. For example, a Process Step with the Business Function of imputing missing values is likely to result, as its Core 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 which can be also used as a part of a quality report associated with the Data Set produced. Another purpose for a Process Metric may be to measure an aspect of the Process Step which is not directly related to the Core Output it produced. For example, a Process Metric may record the time taken to complete the Process Step or other forms of resource utilisation (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.

Reuse of Process Patterns can indicate the possibility to reuse related Business Services. By deciding to reuse a Process Pattern, a designer is actually reusing the pattern of Process Designs and Process Control Designs associated with that Process Pattern. They will receive a new instance of the Process Designs and Process Control Designs. If they then tailor their instance of the Process Designs and Process Control Designs to better meet their needs they will not change the definition of the reusable Process Pattern.

Each Process Step is the use of a Process Design in a particular context (e.g. within a specific Business Process). At the time of execution a Process Step Instance specifies the actual instances of input classes (for example, specific Data Sets, specific Conceptual Variables) to be supplied. Each Process Step Instance may produce unique results even though the Process Step remains constant. Even when the inputs remain the same, metrics such as the elapsed time to complete execution of the process step may vary from execution to execution. For this reason, each Process Step Instance details of inputs and outputs for that instance of the implementation 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.

Statistical Need

requirement, request or other notification that will be considered by a statistical organisation.
The Statistical Need is a proposed or imposed requirement, request or other notification as it has been received by a statistical organisation. A Statistical Need is an expression of a requirement, and is not necessarily well-defined. A related class - Change Definition - is created when a Statistical Need is analysed by the organisation. 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. A Statistical Need may be of a variety of types including Information Request.

Statistical Programme
Business
set of activities to produce statistics on a given Universe within the context of Subject Fields
The Statistical Programme provides the environmental context in which activities to produce statistics within a statistical organisation are conducted. Statistical Programme will usually correspond to an ongoing activity such as a survey or output series covered by GSBPM phase 4-7. Some examples of Statistical Programme are: - Labour Force Survey - Multipurpose Household Survey - National Accounts - Demography - Overseas Arrivals and Departures Related to the Statistical Programme class, there are Statistical Programme Design and Statistical Programme Cycle classes that hold the detailed information about the design and conduct of the Business Process. A Statistical Programme could take as inputs other Statistical Programmes outputs, e.g. national accounts. These activities are all carried out to generate Products. In the case of the traditional approach, an organisation 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 Programme, which will result in a new Statistical Programme Design; or a change to one or more existing Statistical Programmes (for example, to add an additional objective to the Statistical Programme); or result in a new Statistical Programme being created. This does not include statistical support functions such as metadata management, data management (and other overarching GSBPM processes) and design functions. These activities are conducted as part of Statistical Support Activity.

The Statistical Programme Design takes into account requirements such as resource, policy and compliance, specifies new processes, the use of existing ones and the description of relevant methodological information about that set of activities. It is a series of classes that provide the operational context in which a set of Business Processes is conducted. A simple example is where a Statistical Programme relates to a single survey, for example, the Labour Force Survey. The Statistical Programme will have a series of Statistical Programme Design classes 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 Programme Design is created to record the details of the new design.

A Unit Type is used to describe a class or group of Units based on a single characteristic, but with no specification of time and geography. For example, the Unit Type of Person groups together a set of Units based on the characteristic that they are Persons. It concerns not only Unit Types used in dissemination, but anywhere in the statistical process. E.g. using administrative data might involve the use of a fiscal unit.

A Product packages Information Sets for an Information Consumer. The Product is generated according to Output Specifications, which define how the information from the Information Sets are presented (via Presentations) to the Information Consumer. A Provision Agreement between the statistical organisation and the Information Consumer governs the use of a Product by the Information Consumer. The Provision Agreement, which may be explicitly or implicitly agreed, provides the legal or other bases by which the two parties agree to exchange data. In many cases, dissemination Provision Agreements are implicit in the terms of use published by the statistical organisation. For static Products (e.g. paper publications), specifications are predetermined. For dynamic Products, aspects of specification could be determined by the Information Consumer at run time. Both cases result in Output Specifications specifying Information Set data or referential metadata that will be included within the Product.

text used to elicit a response for a Conceptual Variable
A Question may be a single question used to obtain a response, or may be a multiple question, a construct which links multiple sub-questions, each with their own response. A Question also includes a relationship to the Value Domain to document the associated response criteria for the question. A single response question will have one Value Domain associated with it, while a multiple question may have more than one Value Domain. A Question should be designed with re-use in mind, as it can be used in multiple Questionnaires. In a national implementation, Question could be further subtyped into: - QuestionGrid, useful to model questions as grids/tables. It is actually a cube-like structure providing dimension information, labelling options, and response domains attached to one or more cells within the grid. For instance, a two-way table requesting to provide turnovers broken down by affiliates. - QuestionItem, a simple question that is necessarily one dimensional. For example: How old are you?

Register
Exchange
written and complete record containing regular entries of items and details on particular sets of objects
In official statistics, statistical registers and adminisitrative registers (registers maintained by other organisations, usually administrative data owners) are usually distinguished. In GSIM, the information class Register is used to describe both types because the attributes are more or less the same so from the information management point of view, they can be handled as one GSIM class. There is usually a purpose or authority for maintaining the Register and each object in the Register is described using a pre-defined set of characteristics. Examples include business and population registers as used by statistical organisations. Therefore, from statistical perspective, the Register can be interpreted as a set of objects for a given Population, updated on a regular basis, containing information on identification, accessibility of Units and other attributes. The Register contains the current and historical statuses of the Population and the causes, effects and sources of alterations in the Population. In order to better understand how the Register is used in GSIM, the use cases for the different scenarios are explained. These scenarios are: - Register _as Information Set_ maintained and regularly updated by the statistical organisation. - Register _as Information Set_ for survey frames/sample frames. - Register _as Information Set_ for statistical Products. - Register _as Information Set_ used as direct or auxiliary information for the production of statistics. - Register _as Information Set_ as a source of administrative information obtained usually from external organisations.
