One of the three disciplines of AI-Human Thinking. A five-phase systematic methodology for prompt design: Clarify (define what is really needed), Decompose (break the problem into components), Design (architect the prompt structure), Execute (implement and test), Refine (iterate based on results).
The central premise: problem formulation outlasts prompt syntax.
Context & Strategy
How it was born
It emerged from the observation that most people use AI randomly — the equivalent, in the 1990s, of using a computer without knowing what they were doing. PDT was born from the hypothesis that prompting can be taught as a design discipline, not as a technical skill. Developed in parallel with CDT in the second half of 2025.
What it does in practice
Taught as a discipline in The Edge Program curriculum and in AI-Human Thinking programmes for adults. It also serves as the internal methodology at Bitsapiens for the development of meta-prompts and agent systems.
