Context
A Virginia-class submarine program required coordinated execution across four independent operational chains: parts procurement, workforce readiness, facility scheduling, and regulatory review. Each chain ran independently with no shared visibility layer.
Problem
Parts procurement, workforce readiness, facility scheduling, and SUBSAFE regulatory review each operated on separate systems with no unified model. Conflicts and gaps were invisible until they became schedule impacts.
Approach
We built a unified operational map across all four chains and applied propagation modeling to identify the highest-leverage intervention point. Valve assembly allocation emerged as the critical constraint. Dry dock scheduling conflict and SUBSAFE review backlog were surfaced before they became program delays.
What We Built
- Unified operational map across four independent chains
- Propagation modeling to rank constraints by cost and schedule impact
- Valve assembly allocation identified as highest-leverage intervention
- Dry dock conflict surfaced and resolved ahead of impact window
- SUBSAFE review backlog flagged and sequenced before critical path
Results
Planned availability completed in 14.5 months against an 18.5-month projection. Cost overrun reduced from a projected $6.2M to $410K. $5.8M in cost overrun avoided. Deployment window preserved. All four chains mapped and ranked in 9 days.
