In this series of articles, Jeffrey O. Grady, author of “System Verification,” delineates the basics of requirements planning and analysis, an important tool for using Agile programming techniques to achieve better code quality and reliability in complex embedded systems software and hardware projects. Part 2: Decomposition using structure analysis Structured decomposition is a technique for decomposing large complex problems into a series of smaller related problems. We seek to do this for the reasons discussed earlier.

We are interested in an organized or systematic approach for doing this because we wish to make sure we solve the right problem and solve it completely. We wish to avoid, late in the development effort, finding that we failed to account for part of the problem that forces us to spend additional time and money to correct and brings into question the validity of our current solution.
