About This Item
14143.1-2000 is a software measurement standard focused on functional size measurement, helping define how software functionality is described and compared in a consistent way. In the context of computing and processing, it supports clearer assessment of software size beyond lines of code or implementation detail. This matters for planning, estimation, procurement, and benchmarking, where a shared measurement basis can improve comparability across projects and suppliers.
About 14143.1-2000
The standard addresses the definition of concepts used in functional size measurement for software, making the terminology and measurement approach more consistent across technical discussions. As part of the 14143 series, 14143.1-2000 provides a conceptual foundation rather than a product specification. It is intended for situations where software functions need to be measured in a repeatable and understandable way, supporting analysis, reporting, and evaluation in computing environments.
Where is 14143.1-2000 used?
This standard is commonly used in software development, system integration, and IT governance where functional size needs to be stated in a structured way. It may be applied in project estimation, contract reviews, benchmarking, and performance comparison for business systems, control applications, and other software-intensive solutions. Because it defines concepts rather than implementation details, 14143.1-2000 is useful wherever teams need a common language for measuring delivered software functionality.
Importance in practice
In practice, the standard helps reduce ambiguity when software size is used for planning or compliance-related evaluation. A consistent functional size method can improve effort estimation, support procurement decisions, and make testing or acceptance discussions more objective. For organizations handling multiple projects or suppliers, 14143.1-2000 can contribute to better comparison of scope and delivery outcomes, lowering the risk of inconsistent measurement and unclear reporting.
