SNAP Points
SNAP is the acronym for "Software Non-functional Assessment Process," a measurement of the size of non-functional software. The SNAP sizing method complements ISO/IEC 20926:2009, which defines a method for the sizing of functional software. SNAP is a product of the International Function Point Users Group ( IFPUG), and is sized using the “Software Non-functional Assessment Process (SNAP) Assessment Practices Manual” (APM) now in version 2.4. Reference “IEEE 2430-2019-IEEE Trial-Use Standard for Non-Functional Sizing Measurements,” published October 19, 2019. Also reference ISO standard “Software engineering — Trial use standard for software non-functional sizing measurements,” (https://www.iso.org/standard/81913.html), published October 2021. For more information about SNAP please visit YouTube and search for "IFPUG SNAP;" this will provide a series of videos overviewing the SNAP methodology.

Acronym
An acronym is a type of abbreviation consisting of a phrase whose only pronounced elements are the initial letters or initial sounds of words inside that phrase. Acronyms are often spelled with the initial Letter (alphabet), letter of each word in all caps with no punctuation. For some, an initialism or alphabetism connotes this general meaning, and an ''acronym'' is a subset with a narrower definition; an acronym is pronounced as a word rather than as a sequence of letters. In this sense, ''NASA'' () is an acronym, but ''United States, USA'' () is not. The broader sense of ''acronym'', ignoring pronunciation, is its original meaning and in common use. . Dictionary and style-guide editors dispute whether the term ''acronym'' can be legitimately applied to abbreviations which are not pronounced as words, and they do not agree on acronym space (punctuation), spacing, letter case, casing, and punctuation. The phrase that the acronym stands for is called its . The of an acron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Measurement
Measurement is the quantification of attributes of an object or event, which can be used to compare with other objects or events. In other words, measurement is a process of determining how large or small a physical quantity is as compared to a basic reference quantity of the same kind. The scope and application of measurement are dependent on the context and discipline. In natural sciences and engineering, measurements do not apply to nominal properties of objects or events, which is consistent with the guidelines of the International Vocabulary of Metrology (VIM) published by the International Bureau of Weights and Measures (BIPM). However, in other fields such as statistics as well as the social and behavioural sciences, measurements can have multiple levels, which would include nominal, ordinal, interval and ratio scales. Measurement is a cornerstone of trade, science, technology and quantitative research in many disciplines. Historically, many measurement syste ...

IFPUG
The International Function Point Users Group (IFPUG) is a United States, US-based organization with worldwide chapters of Function point analysis metric software users. It is a Nonprofit organization, non-profit, member-governed organization founded in 1986. IFPUG owns Function point, Function Point Analysis (FPA) as defined in ISO-standard, ISO 20296 which specifies the definitions, rules and steps for applying the IFPUG's functional size measurement (FSM) method. FPA can be traced to the work of Allan Albrecht of IBM who pioneered functional sizing in 1979 which derived a functional size of product value distinct and disassociated from lines of code, technology, or software language. Functions IFPUG maintains the Function Point Counting Practices Manual (CPM), and the SNAP Assessment Practices Manual, the recognized industry standards for Software sizing#Functional software-sizing methods, functional and Software sizing#Non-functional software-sizing methods, non-functional siz ...

International Organization For Standardization
The International Organization for Standardization (ISO ; ; ) is an independent, non-governmental, international standard development organization composed of representatives from the national standards organizations of member countries. Membership requirements are given in Article 3 of the ISO Statutes. ISO was founded on 23 February 1947, and () it has published over 25,000 international standards covering almost all aspects of technology and manufacturing. It has over 800 technical committees (TCs) and subcommittees (SCs) to take care of standards development. The organization develops and publishes international standards in technical and nontechnical fields, including everything from manufactured products and technology to food safety, transport, IT, agriculture, and healthcare. More specialized topics like electrical and electronic engineering are instead handled by the International Electrotechnical Commission.Editors of Encyclopedia Britannica. 3 June 2021.Internatio ...

Function Point
The function point is a "unit of measurement" to express the amount of business functionality an information system (as a product) provides to a user. Function points are used to compute a functional size measurement (FSM) of software. The cost (in dollars or hours) of a single unit is calculated from past projects. Standards There are several recognized standards and/or public specifications for sizing software based on Function Point. 1. ISO Standards * FiSMA: ISO/IEC 29881:2010 Information technology – Systems and software engineering – FiSMA 1.1 functional size measurement method. * IFPUG: ISO/IEC 20926:2009 Software and systems engineering – Software measurement – IFPUG functional size measurement method. * Mark-II: ISO/IEC 20968:2002 Software engineering – Ml II Function Point Analysis – Counting Practices Manual * Nesma: ISO/IEC 24570:2018 Software engineering – Nesma functional size measurement method version 2.3 – Definitions and counting guidelines for t ...

Benchmark (computing)
In computing, a benchmark is the act of running a computer program, a set of programs, or other operations, in order to assess the relative performance of an object, normally by running a number of standard tests and trials against it. The term ''benchmark'' is also commonly utilized for the purposes of elaborately designed benchmarking programs themselves. Benchmarking is usually associated with assessing performance characteristics of computer hardware, for example, the floating point operation performance of a CPU, but there are circumstances when the technique is also applicable to software. Software benchmarks are, for example, run against compilers or database management systems (DBMS). Benchmarks provide a method of comparing the performance of various subsystems across different chip/system architectures. Benchmarking as a part of continuous integration is called Continuous Benchmarking. Purpose As computer architecture advanced, it became more difficult to compa ...
