The Aerospace and Defense industry has a large problem with increasing cost and complexity in their projects. This is the result of Aerospace and Defense projects becoming larger and more sophisticated. To solve this problem, the complexity that has been introduced has to be identified, reduced, and managed. This will lower the overall cost and keep projects on schedule. As an example, Tesla puts a strong emphasis on modularity (reduced complexity) across all their hardware. So during the recent chip shortage, they were able to quickly switch to chips that were available and continue to make and sell cars with minimal disruptions. One technology that can be used to reduce complexity (and increase modularity) is the Dependency Structure Matrix (DSM).
