Research on Lag Structure Analysis of System Engineering Milestone Schedules and Regression-Based Timing Optimization in Parts Localization

Q: What does this research mean for the field?

In parts localization projects, delays in System Requirements Review (SRR) and Critical Design Review (CDR) significantly drive Test Readiness Review (TRR) delays, with optimal milestone timings identified at approximately 6, 12, 18, and 23 months post-agreement. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

Key Points

The study aims to quantitatively analyze the lag structure of milestone delays in parts localization projects and propose optimal timing for execution.
Collected data on scheduled versus actual completion dates for 41 parts localization projects.
Conducted regression analysis based on data from completed system engineering milestones (SRR, PDR, CDR, TRR).
Ensured model stability regarding linearity, independence, homoscedasticity, and multicollinearity.
TRR delays were significantly influenced by prior delays in SRR and CDR.
The regression model satisfied the Gauss-Markov conditions and provided reliable estimates.
Optimal timing: SRR at about 6 months, PDR at 12 months, CDR at 18 months, and TRR at 23 months post-agreement.

Implication

Analyzes milestone scheduling delays in parts localization, indicating optimal timing suggestions.
