Is Claude Code enough? See what each stage of AI adoption does to delivery
Giving every engineer an AI coding assistant speeds up typing, not shipping. Enter a few numbers about your team and see how lead time and delivery capacity change as you add AI code review, a full AI workflow and AI-assisted refinement.

Code gets written about 40% faster, but coding is only part of a ticket's life. Bigger PRs wait longer for review, and more defects come back as rework. The time saved at the keyboard mostly moves to the review queue.

How the calculator works
A ticket spends its life in five phases: refinement and clarification, coding, code review and waiting, testing and QA, and rework. On a typical team without AI, coding is only about 30% of that time. The model starts from that split and applies an estimated speed-up or slow-down to each phase at each stage of AI adoption.
That is why an AI coding assistant on its own adds so little. It cuts coding time, but larger pull requests wait longer for review, and more defects come back as rework. Delivery only speeds up when review, QA and refinement change too, which is what an AI-native software development lifecycle (SDLC) does.
The factors are modelled estimates based on public research and our own client work. Your team will differ. The AI Engineering Snapshot replaces them with numbers measured from your own git history and issue tracker.
What the research says
Each 25% increase in AI adoption was associated with an estimated 1.5% drop in delivery throughput and a 7.2% drop in delivery stability.
DORA, Accelerate State of DevOps 2024AI adoption now correlates with higher throughput, but still with lower delivery stability: more change failures and rework.
DORA, State of AI-assisted Software Development 2025Teams with high AI adoption completed 21% more tasks and merged 98% more pull requests, while PR review time rose 91%.
