INTRODUCTION

English translation pending.

CORE DEFINITION

PLAN is a compact planning template with four elements. Purpose states why the work is being done and what changes if it is not. Limits state the constraints the plan must respect, such as deadline, budget, and scope boundaries. Actions list the key steps. Next names a single immediate action and its owner. The template is designed for use in limited time, such as the end of a meeting, where a full planning document is impractical. It assumes a plan without stated limits expands beyond available resources, and a plan without a next step produces agreement without activity.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Use purpose statement: write what changes if the work is not done, to test whether it should be. - Use limit declaration: state the deadline, budget, and scope boundaries the plan must respect. - Use next-step assignment: name one immediate action and the person responsible for it.

Anchor fast decisions

Plans fail in two predictable ways: they expand past their constraints, and they end without anyone starting. Stating the limits first constrains the design, so scope decisions are made against a boundary rather than added incrementally until the plan is unachievable. Stating the purpose supplies the criterion for cutting scope when the limits bind, since elements that do not serve the purpose can be dropped. Naming a single immediate action with an owner converts the plan into activity.

CATWOE Analysis

Before solving a system problem, clarify six elements: Customers (beneficiaries), Actors (executors), Transformation (the process of turning input into output), Worldview (the worldview of why it is done), Owner (the owner), and Environment (environmental constraints).

Hill Chart

Divide task progress into two phases: uphill (figuring out what to do, eliminating unknowns) and downhill (specific execution, just manual work).

Single Threaded Leader

For important projects, a leader must be assigned who is responsible for nothing else (single-threaded), fully owns the success or failure of the project, and has the authority to mobilize resources, rather than relying on cross-departmental collaboration (which is often inefficient).
