To compute function points (FP), the following relationship is used FP = Count – total × (0.65 + 0.01 × Σ(Fi)) where Fi (i = 1 to n) are value adjustment factors (VAF) based on n questions. The value of n is
14
Count-total is the unadjusted function point count, the weighted sum of external inputs, external outputs, external inquiries, internal logical files and external interface files.
It is then adjusted for the general characteristics of the system. In Pressman's formulation these are answers to 14 questions (data communications, distributed processing, performance, heavily used configuration, transaction rate, online data entry, end-user efficiency, online update, complex processing, reusability, installation ease, operational ease, multiple sites, facilitate change), each rated from 0 (no influence) to 5 (essential).
Hence \(\Sigma F_i\) ranges from 0 to \(14 \times 5 = 70\), so the adjustment factor \(0.65 + 0.01 \times \Sigma F_i\) lies between 0.65 and 1.35, i.e. ±35 %. The number of questions is n = 14.
Hence, the answer is 14.
