In a function oriented design, we minimize cohesion and maximize coupling maximize cohesion and minimize coupling maximize cohesion and maximize coupling minimize cohesion and minimize coupling
To compute function points $(FP)$, the following relationship is used $FP$ = Count - total $\times (0.65 + 0.01 \times \sum(F_{i}))$ where $F_{i} (i = 1$ to $n$) are value adjustment factors $(VAF)$ based on $n$ questions. The value of $n$ is $12$ $14$ $16$ $18$
