When a PE firm installs the same SDLC across every portfolio company, something changes. Projects stop failing for the same reasons. Lessons learned at one company prevent failures at the next. The portfolio gets smarter with every engagement.
What problem are we solving? Who is affected? What does success look like? Defined before anyone touches a system.
How does it work? What systems are touched? Dependencies approved before development starts.
If data is involved, what changes? Defined before any migration runs.
How long does this take? Validated against the lessons learned corpus.
Development starts. Only after Gates 1–4 pass.
Every deployment passes the QA gate before going live. No exceptions.
Project closes. What happened? What worked? What to avoid? Written into the corpus.
The SDLC is configured to each portfolio company's own business rules and their own templates. Adoption happens because the workflow advances automatically when the artifact is right — and warns management when something is stuck. The pain of not following it is visible. The reward for following it is speed.
For software projects: high-quality artifacts feed directly into Mesh Build Squad execution. Better artifacts = faster delivery = lower cost. The PE firm sees that math clearly.
Every project across every portfolio company writes into the same intelligence layer. Over time, LeanStream knows that companies in certain industries consistently underestimate integration effort. That pattern surfaces in the estimate before the mistake is made — not after. No individual company could build this. It takes a portfolio to generate it.
Lessons reviewed before project close. PE Product Owner decides: change course or continue.
Patterns visible across all portfolio companies. Anonymized. Always available.
Every project documented, gated, and auditable. The data room is always clean.
