Build vs Buy — Aerospace and Defense
Weigh SaaS subscriptions against a custom build for Aerospace and Defense — see the multi-year total cost of ownership and which path wins.
What this means for Aerospace and Defense
- Certification cycles take years; every design change triggers a paperwork avalanche across DO-178C, DO-254, AS9100, and FAA/EASA evidence packs.
- Configuration management across decades-old platforms still relies on PDM systems that were modern in 2003.
- MRO turnaround time is the operational pain point — aircraft on ground (AOG) costs are catastrophic and parts demand forecasting is largely manual.
Where it pays to act
- Predictive maintenance on aircraft and platform fleets using sensor and inspection data.
- Document understanding across cert packages, technical orders, and supplier quality records.
