Benefits of the COSMIC method
Size is the most significant factor that determines software effort/cost/timelines. Effective size measurement leads to better metrics, estimation and greater certainty and control. You can learn the basics of COSMIC in a day and reap the rewards for the rest of your career!

The COSMIC method is supported by:
- comprehensive documentation; the Measurement Manual has been translated into many languages,
- guidelines that describe how to apply the method to specific types of software, e.g. data warehouse or SOA software, or for specific project management approaches, e.g. Agile methods,
- case studies for business application and real-time software,
- tools for collecting and reporting measurement data,
- tools for analysing requirements for automating size measurement,
- comprehensive benchmark data available via isbsg.org. Many measurements of software projects in different domains have shown an excellent correlation of COSMIC-measured sizes with project effort,
- vendor services of commercial partners, including suppliers of training, consultancy, estimating tools, etc,
- certification exams for applying the method in general or in the early stages,
- guidelines for assuring the accuracy and the comparability of measurements,
- documented variants for approximate COSMIC sizing that can be used early in the life of a project when all the details for the requirements have not yet been established, or for quick size measurement (see 1),
- active user groups on Linkedin (‘COSMIC Users Group’) and Twitter (@COSMIC_FSM),
The COSMIC method is being used successfully around the world for project performance measurement, for estimating, project scope control etc.
The COSMIC method is also being extensively studied by the academic research community. Notable amongst these are several approaches to automating COSMIC size measurement from, e.g. requirements held in UML and from executing programs.
The Knowledgebase has a large library of research and conference papers

3 Recent research (see 1) has demonstrated that COSMIC sizes correlate very well with sizes of the same software measured by the MkII FP method. The size scale of the latter method was calibrated by relating sizes to project effort. The good correlation implies that the COSMIC size scale should be suitable for the purposes for which it was designed (as a component of measuring project performance and as input for project effort estimation), even though the size method was not calibrated against effort.
