The COSMIC Group with Bernard Londeix
Dedicated to the COSMIC Method

The COSMIC Group was started in 1998 as a special interest group which became a group of global interest whilst developing what is now known as the COSMIC method of functional sizing. This is the most advanced method of measuring a functional size of software applicable to business, real-time and infrastructure software. It is easy to learn and simple to use. The COSMIC Functional Sizing method is entirely 'open'; all method documentation is available in the public domain for free download.

The new COSMIC Measurement Manual is made up of three Parts each describing a particular aspect of the Method. They are freely downloadable from the web site of COSMIC Functional Sizing.

Part 1: Principles, Definitions and Rules.
This Part states the Principles, Definitions and Rules of the COSMIC Method as well as the COSMIC measurement process.

Part 2: Guidelines.
This document is to provide guidance to the practitioners for the application of the COSMIC ISO 19761 Function Points standard presented in Part 1.

Part 3: Examples.
This is an introduction to the large number of examples of Functional User Requirements (FUR) which are documented as COSMIC Case studies freely available at COSMIC Functional Sizing.

'Push' Team

Colin Hammond notes with Jayakumar, Frank and Charles that the website does not rank well in the search engines (compared to other similar subjects) and it is quite hard for new visitors to learn incrementally about the methodology, it's use, validity etc. So Colin and his Team propose 3 immediate actions:

  1. Adopting a standard COSMIC appellation: COSMIC Functional Sizing
  2. Keeping the COSMIC use of up to date, and;
  3. Calling for supporting suggestions from the Group.
The Group needed such a wellcome 'pushing' initiative. Thanks Colin!
