Certification and production: the two processes that gate everything
In most industries the question is whether something can be built and sold. In this one it is whether a regulator will approve it and whether the supply chain can go faster. Both are slower than any engineering problem in the branch, and both decide programme value.
In one sentence
Aerospace certification and production covers the approval of a design and its manufacture by an airworthiness authority, the process of increasing output rate across a tiered supply chain, and the rules governing parts and repairs in service.
Certification is not a test at the end. It is a process running through the entire development: agreeing the certification basis, showing compliance with every applicable requirement by analysis, test or inspection, and producing evidence a regulator accepts. The evidence is a deliverable comparable in effort to the design itself.
Production rate is the other gate. Deliveries — and therefore revenue — depend on the slowest constrained part in a chain several tiers deep, and rate increases have to be approved as well as physically achieved, because the authority also oversees the production system that builds approved articles.
How this breaks down
Split by which process is doing the gating: approval, rate, or the rules in service.

What this depends on
1 of these is marked as a chokepoint: a handful of qualified suppliers, a multi-year lead time, or a single geography.

Airworthiness authority approval
Nothing flies commercially without it, and the timeline is not under the manufacturer's control.
- Resource
Authority and delegated engineering capacity
Compliance findings are made by regulator staff and by the manufacturer's delegated organisation. When either is short of people the programme waits, and no amount of money shortens it.
- Standard
Bilateral validation agreements
A certificate from one authority is accepted elsewhere under bilateral arrangements. Where independent review has increased, worldwide approval becomes a serial process rather than a parallel one.
What depends on this
Other pages in this map that name Certification and rates as something they cannot do without.

How these pages are written
Each page explains one technology in plain language, states what it depends on, and names companies by what they supply at that step. Company roles are described qualitatively and deliberately carry no market shares, revenue figures or rankings — those change faster than an explainer can, and a stale number is worse than none. Ticker links point at company pages on this site and are provided for reference only.
Nothing here is investment advice, a recommendation, or a forecast. A company named on a page about a technology is not thereby a good investment, and the chokepoints described are structural facts about supply chains rather than predictions about prices. Technology moves; where a page describes something as unresolved or in development, that was true when it was written.
