A 90-day MOSAIC plan for aircraft manufacturers

The decision behind this topic

For manufacturers beginning MOSAIC evaluation, the useful question is not simply what MOSAIC says. The work is producing a fundable plan without pretending the full program is already known. The management decision is what the next gate requires and which uncertainties must be retired first. That requires an aircraft-specific record, not a generic interpretation copied into a schedule.

A credible program distinguishes confirmed requirements from assumptions, ties each conclusion to the configuration it covers, and gives unresolved items an owner and a decision date. This is especially important when prior certification work, supplier evidence, or commercial forecasts are being reused in a new U.S. context.

Evidence to put on the table

A practical way to proceed

1. 1

   days 1-30: define scope and sources

2. 2

   days 31-60: assess evidence and production readiness

3. 3

   days 61-90: approve the closure roadmap and governance

The output should be a traceable recommendation with conditions, not an unsupported yes or no. Where evidence is incomplete, show the closure method, cost and schedule exposure, and the event that will change the decision.
