The funnel narrows from a broad starting point to a precise fit, then loops — step 4 feeds learning back into steps 1–3 throughout delivery. You tailor the life cycle, processes, engagement (people), tools, methods & artifacts — but the 12 principles always apply.
| Dimension | Pushes toward Predictive ▸ | ◂ Pushes toward Adaptive |
|---|---|---|
| Requirements | Stable, clear, well understood | Emerging, uncertain, fast-changing |
| Risk & regulation | Safety-critical, heavily regulated | Low regulatory burden |
| Cost of change | Expensive to change late | Cheap & easy to change |
| Delivery cadence | One large, integrated delivery | Frequent small increments |
| Customer involvement | Limited / milestone-based | Continuous & collaborative |
| Size & duration | Large, long, many interfaces | Small-to-medium, shorter |
| Team & culture | Distributed, low agile maturity | Co-located/empowered, agile-fluent |
