software products in the form of numbers based on the information processing requirements identified, and is suitable for performance measurement and evaluation related to software product activities: In the case of MkII function point analysis, "information processing requirements" refers to the functional requirements set of application software product commissioned users (not including any technical and quality requirements), "activities" can be the development, optimization, or maintenance of software products to meet software requirements: The MkⅡ function point analysis method was published by Charles Symons in:1991 in "Scaling and Evaluation of Software: MkⅡ Function Point Analysis" Defined in , developed internally at KPMG during 1985-1986 and protected as a proprietary method, is now publicly available: British Software Measurement Association The Society's Measurement Practices Committee (MPC) is currently the interpretation body for this method and is responsible for its continued development: The purpose of this document is to establish rules for the use of MkII Function Point Analysis (FPA) and to provide standards for the MkII Function Point Analysis method: The relationship between the MkII and IFPUG function point analysis methods is as follows: a) Both of these software product size measures are subtle but significantly different: The main difference is the finer grained The MkⅡ function point analysis is a continuous measurement, and once the IFPUG reaches the threshold, the component size is limited, and the MkⅡ function point The point analysis method is designed to better reflect the complexity of the intermediate processing of commercial systems containing large amounts of data: due to scale measurement It is based on logical transactions and entities, in which software requirements and functional specifications are usually expressed, so the MkII functional scale Measurement has nothing to do with developing techniques or methods for implementing software: b) In general, both methods give approximately the same software size at around 400 function points (for individual software projects Say, averages can be quite spread out): For larger-scale software, MkII function point analysis will calculate continuously increasing, relative IFPUG method for higher scale values: c) For some applications (such as portfolio management of securities), the two methods may be considered equivalent: However, if used for the most Common performance measurement and estimation tend to use the same scale, and only use a display average when necessary: The relationship formula can be converted: System and software engineering functional size measurement MkⅡ Function Point Analysis Method1 ScopeThis document specifies the usage rules, measurement process, general requirements, specific scene measurement requirements, and scale adjustment of the MkⅡ function point analysis method: methods and methods of estimating workload: The MkII function point analysis method is a method that helps to measure process efficiency and manage application software development, Ways to enhance or maintain activity costs: It measures the size of a software product independently of the technical characteristics of the software and is only relevant to users: it can: --- Early application in the software development process; ---Consistent and continuous application in the software life cycle; --- Explained by business, and can be understood by users who use the software: This document applies to the functional size measurement of any software application described in terms of logical transactions, where each logical transaction includes Input, processing and output components: MkII's measurement rules apply to application software from the field of business information systems, where each logic Transaction processing components are mainly responsible for data storage or retrieval: MkII may also be suitable for software in other fields, but it should be noted that its measurement specifications It does not consider the scale of complex algorithms common in scientific engineering software, nor does it particularly consider the real-time requirements: Other areas are also possible The MkII function point analysis method is used, but the rules given in this document may need to be extended or new interpretations made: MkII function Point analysis methods can be used to measure the following scales: --- Requirements specification or functional specification for new applications or changes to existing applications; ---Requirements for existing running applications, whether custom-made, or complete business software solutions, whether batch, or is implemented online: Whether used directly or in combination with other measures such as workload, defect count, etc:, MkII function point analysis can be used to achieve a variety of Measurement purposes, including: --- Measuring project or organizational performance (productivity, delivery and quality); --- compare internal and external IT performance; --- Compare the quality and reliability of the apps; ---Compare the standardized development, maintenance and support costs of applications on different platforms; --- Estimate the resource requirements, duration and cost of the project; ---Assist in assessing the cost and risk elements of the business case for new projects; ---Assist in identifying all requirements before developing the application; --- Control tempo or range changes in the project; --- Assign tasks to team members; --- Determine the size of the application asset base; --- Prepare effective, high-level functional documentation for legacy systems that do not update functional documentation in a timely manner; --- Determine the replaceable value of the application: MkII function point analysis is independent of project management methods (such as waterfall, spiral, incremental, etc:), and also independent of the development method adopted (such as object-oriented, information engineering, etc:): It is a measure of logic and business requirements, independent of implementation:2 Normative referencesThe contents of the following documents constitute the essential provisions of this document through normative references in the text: Among them,
