Field notes from Shriram IT Ventures delivery work on SaaS: Integration Patterns Guide: the constraints that matter, the shortcuts that haunt you, and a checklist we still use.
Who this is for
Ignore the buzzwords. For SaaS: Integration Patterns Guide, the hard constraint is usually data ownership or ops capacity — not how many features fit on a roadmap slide.
Decisions that still look smart in 18 months
Teams that write trade-offs down before coding burn fewer sprints when a stakeholder changes their mind mid-build. We keep ADRs short on purpose.

Ignore the buzzwords. For SaaS: Integration Patterns Guide, the hard constraint is usually data ownership or ops capacity — not how many features fit on a roadmap slide.
Failure modes we keep seeing
Ship a thin vertical slice, measure, then widen. Big-bang rewrites rarely survive the first month of real traffic.
How we measure rollout

We update this when delivery patterns change on live client work.
