BS ISO IEC 25024-2015 pdf free download – Systems and software engineering — Systems and software Quality Requirements and Evaluation (SQuaRE) — Measurement of data quality.
1 Scope
This International Standard defines data quality measures for quantitatively measuring the dataquality in terms of characteristics defined in ISO/IEC 25012.
This International Standard contains the following:
-a basic set of data quality measures for each characteristic;
– a basic set of target entities to which the quality measures are applied during the data-life-cycle;
an explanation of how to apply data quality measures;
-aguidancefororganizationsdefiningtheirownmeasuresfordataqualityrequirementsandevaluation.lt includes, as informative annexes, a synoptic table of quality measure elements defined in thisInternational standard(Annex A), a table of quality measures associated to each quality measureelement and target entitiy(Annex B), considerations about specific quality measure elements(AnnexC), a list of quality measures in alphabetic order (Annex D), and a table of quality measures grouped bycharacteristics and target entities (Annex E).
This International Standard does not define ranges of values of these quality measures to rate levels orgrades because these values are defined for each system by its nature depending on the system contextand users’ needs.
This International Standard can be applied to any kind of data retained in a structured format within acomputer system used for any kinds of applications.
People managing data and services including data are the primary beneficiaries ofthe quality measures.This International Standard is intended to be used by people who need to produce and/or use dataquality measures while pursuing their responsibilities.
– Acquirer (an individual or organization that acquires or procures data from a supplier).
– Evaluator (an individual or organization that performs an evaluation, which can, for example, be a
testing laboratory, the quality department of an organization, a government organization, or a user).Developer (an individual or organization that performs development activities includingrequirements, analysis, design, implementation, and testing data during the data-life-cycle).
Maintainer (an individual or organization that performs operation and maintenance activities of data).Supplier (an individual or organization that enters into a contract with the acquirer for the supplyof data or service under the terms of the contract).
– User (an individual or organization that uses data to perform a specific function).
Quality manager (an individual or organization that performs a systematic examination of the data).Owner (an individual or organization that takes responsibility for the management and financialvalue of the data with the legal authority and responsibility to establish for them evaluation,collections, access, dissemination, storage, security, and cancellation).
This International Standard takes into account a large range of data of target entities.
It can be applied in many types of information systems, for example, such as follows:
— legacy information system;
— data warehouse;
— distributed information system;
— cooperative information system;
— world wide web.
The scope does not include the following:
— knowledge representation;
— data mining techniques;
— statistical significance for random sample.
2 Conformance
Any measurement process for requirement, implementation, or evaluation of data quality shall be conformed to this International Standard:
a) selecting data quality characteristics to be specified or evaluated as defined in ISO/IEC 25012;
b) selecting a target entity for which data quality characteristic shall be measured;
c) selecting the appropriate data quality measures defined in Clause 8 by each data quality characteristic concerning a target entity;
d) providing the rationale for any changes when modify the data quality measures;
e) listing any additional quality measures or quality measure elements used that are not included in this International Standard.BS ISO IEC 25024 pdf download.
