Agentic PDLC fundamentals

The four phases, the one hard gate, the eight loops and the evidence that crosses each hand-off: the model every other track builds on.

1. 1Evolution of the PDLC: from waterfall to agentic deliveryHow the product lifecycle evolved from waterfall to agile, DevOps and agentic delivery, and what genuinely changes when a model does part of the work.8 min · Beginner
2. 2Why agentic AI projects fail: 7 failure modes and fixesGartner expects over 40% of agentic AI projects to be cancelled by 2027. The seven failure modes behind that, why normal checks miss them, and the fix for each.7 min · Beginner
3. 3P0 Frame: how to decide if an AI agent is worth buildingP0 Frame is the agentic PDLC's first phase: turn a request into a measured pain, test whether it needs AI at all, size the value and set autonomy per action.8 min · Beginner
4. 4P1 Design & Spec: write a spec an AI agent can build fromP1 Design & Spec turns a framed problem into an eight-field spec with EARS acceptance, a bar per slice and an authority budget an AI agent can build from.8 min · Intermediate
5. 5The hard gate: the hand-off you can't skip in AI deliveryOnly one hand-off in the agentic PDLC halts the build. Which decisions are hard, which run behind a placeholder, and the four questions that tell them apart.7 min · Intermediate
6. 6P2 Build & Prove: how to build an AI agent in proven slicesP2 Build & Prove builds an AI agent in bolts of hours or days, gates every merge on a per-slice bar and ends with a shadow run beside the people doing the job.8 min · Intermediate
7. 7P3 Run & Learn: how to run an AI agent in production safelyP3 Run & Learn covers cut-over, rollback, drift and cost for AI agents in production, and the two-number report that decides whether the programme survives.7 min · Intermediate
8. 8The 8 feedback loops of AI delivery and the 3 teams forgetEight loops turn the agentic PDLC from a line into a ring. Five close themselves; three (cost, incident, governance) close only if a named person makes them.7 min · Intermediate
9. 9The evidence pack: what must exist before each AI hand-offThe minimum artefacts owed at each hand-off of an agentic AI project, and the one column that separates a real gate from a formality: enforced, or only written?7 min · Intermediate
