Weight features for level of complexity3. Adjust to account for 14 factors affectingfunctional sizeReference CopyGaffney and Cruikshank identify the following14 factors for function point estimation:‣ Data communications‣ Distributed functions‣ Performance‣ Heavily used operational configuration‣ Transaction rate‣ Online data entry‣ Design for end‐user efficiency‣ Online update (for logical internal files)‣ Complex processingNot for Distribution‣ Reusability of system code‣ Operational ease‣ Multiple sites‣ Ease of changeIEEE Computer SocietyReference: Thayer, Richard H.
