Help contents. However, they don't take data flow into account. Data flow, or information flow, means parameter passing and variable access. Watching for procedures with high informational complexity can reveal the following issues: procedure has more than one function; procedure is a stress point in the system with information traffic ; procedure has excessive functional complexity. High informational complexity indicates candidate procedures for extensive testing or redesign. Several metrics have been developed to measure information flow complexity.

Function point analysis is a widely cited method for estimating software project size, which is an important activity of project management. At the beginning stage of planning, the top-down approach can be applied. Having obtained more systems specifications at later stages, the bottom-up approach might also be used to improve the accuracy of the estimation. However, the bottom-up approach is not a conventional way of function point analysis. There was no empirical evidence showing the difference between the fully informed top-down approach and the bottom-up approach.
