  8. #cosmictalk A02 – Software offers a service to its users. --> functionality. Comparing components? Quantity of functionality?
  9. #cosmictalk A03 – Since the advent of software, in the 60s, a number of methods have been in use: SLOC, IFPUG, MkII FPA, COSMIC
  10. #cosmictalk A04 – SLOC (Source Lines Of Code) measures a number of source statements. Very poor approx. of the quantity of functionality
  11. #cosmictalk A05 – SLOC appears late in the project – Too late for estimating the project. SLOC size depends on the coding language. Variable
  12. #cosmictalk A06 – SLOC not rejected by CMMi, SPICE & others -> excess of trust. May be useful for dimensioning the object code memories
  13. #cosmictalk A07 – SLOC is insufficient- Choose a better method. 3 measurement methods are currently available: MkII FPA, IFPUG, & COSMIC
  14. #cosmictalk A08– IFPUG (IEEE TSE 1983). Identifies 5 artefacts: EI, EQ, EO, ILF & EIF. Counting rules exist, but based on conventions
  15. #cosmictalk A09 – IFPUG appeared the first, hence, widely used. Can be used early in the project life cycle. Useful for estimation
  16. #cosmictalk A10 – IFPUG may be inaccurate because of its conventions and inadequacy of its rules. It’s an evaluation by convention
  17. #cosmictalk A12 – MkII FPA (1991) A piece of software holds a group of functional processes. Each is structured in a number of Transactions
  18. #cosmictalk A13 – MkII FPA model: Transactions ‘description by <Entrees, Processes, Exits>.Entries and Exits depend on the N# of attributes
  19. #cosmictalk A14 – Processes depends on the number of Entities referenced by Transactions. See method on uksma.co.uk
  20. #cosmictalk A15 – MkII FPA is usable early in the PLC: useful for estimation. Not adequate for real-time apps. Is also based on conventions
