What is the optimum level of Systems Engineering (SE) on a program?

Explanation:
The level of Systems Engineering effort should be enough to clearly define requirements and architecture early, while avoiding excessive overhead. Early, solid SE work reduces risk and costly rework later in the program, but pushing SE too far into process overhead can waste resources and slow progress. Around twenty percent of the total program effort tends to be the sweet spot where the benefits of upfront definition and system design balance the cost of SE activities with the downstream cost of changes. The other options are either too small to meaningfully reduce risk and rework or too large, adding unnecessary overhead without proportional gains.
