Onboarding audit and doc gap reports for open-source Java frameworks

Engineering managers at companies standardizing on an Apache framework — OFBiz for ERP, Sling for content management, UIMA for NLP pipelines — face a recurring problem they usually discover too late: their team's onboarding time is ballooning because the framework's documentation doesn't support self-service learning. A developer asks their manager for help with an advanced feature, the manager looks at the docs, and both realize the information simply isn't there.

The reason this hasn't been productized is that most tooling in developer experience focuses on a company's own internal docs, not third-party open-source dependencies. There's no structural incentive for an Apache PMC to measure how well their docs serve new adopters — they don't track conversion from 'evaluated the framework' to 'shipped with it successfully.' The pain is entirely absorbed by the companies using the framework, not by the people writing the docs.

What an engineering lead actually needs is an honest, structured audit: which areas of a given framework have thin documentation, where are the known gaps in examples for common use cases, and how does their team's specific usage profile map to those gaps. This is especially acute when a major version ships — users said explicitly they need 'documentation for major updates,' meaning the delta between versions is itself undocumented.

This is a business because the need recurs with every framework upgrade and with every new engineer hired onto the team. A company using Apache OFBiz for their ERP doesn't just need the audit once — they need to know what changed in documentation coverage when OFBiz 18.12 vs. 22.01 shipped, and which of those gaps will affect their specific modules. That's a subscription problem, not a one-time consulting engagement.

What to build

Build a doc coverage scanner that ingests an Apache framework's official documentation and changelog, maps documented versus undocumented public APIs and configuration options, and generates a gap report sorted by frequency of community questions — delivered as a structured PDF or Notion export a team lead can act on.

Where to start

Start with companies upgrading Apache OFBiz across a major version boundary — the changelog is dense, the migration is painful, and the engineering lead has a concrete upcoming event (the upgrade) that makes the doc gap report immediately actionable and worth paying for.

The hard part

Selling a documentation audit to engineering leads requires them to already believe their team's time loss is doc-related rather than skill-related — getting that first customer to attribute onboarding friction to framework docs, rather than blaming their own hiring, is the hardest early sales conversation.

How it makes money

Per-project audit fee ($500–1,500 for initial gap report) plus an annual subscription ($200–400/month) for continuous monitoring that alerts the team when a new framework release lands without corresponding documentation updates for the APIs they actively use.
