Define the system and unit of analysis
Specify process, population, product, time window, boundaries and aggregation level. Without a defined unit of analysis, measures and comparisons may represent different phenomena.

5W2H — Action Plan
Turns an intention into an action plan by making explicit what will be done, why, when, by whom, where, how and at what cost.

MANAGEMENT QUESTION
The problem the tool must make decidable.
Before opening a form, define the question that must be answered. A management tool is useful when it reduces ambiguity, exposes assumptions and makes clear which decision will be made from the evidence produced.
PLN-01Which actions turn a decision into a verifiable commitment—with owner, deadline, method, location, rationale and resources made explicit?
Continuous improvement requires separating opinion from evidence and turning a broad problem into a sequence that can be observed, tested and revised. The tool creates value when it starts from an explicit current condition, applies criteria before concluding and ends with a verifiable decision — not merely a completed document.
Use it when you need to reduce variation, solve recurring problems, test changes, prioritize causes or preserve learning beyond the meeting in which it was produced.
02
METHOD ARCHITECTURE
Technical construction: from operational definition to evidence.
A robust plan starts by defining the expected outcome and the starting condition. It then organizes actions, owners, deadlines, criteria and resources. Order matters: when action precedes diagnosis, the plan becomes a task list without a theory of results.
Define criteria before evaluation
Translate abstract concepts into operational definitions, scales, classification rules and data sources. Criteria should exist before the result to reduce retrospective interpretation.
Preserve traceability
Link each conclusion to data, observations, assumptions and owners. When a score is used, retain its components; when a hypothesis is used, record how it will be tested.
During review, look for actions without owners, dates disconnected from dependencies, costs without assumptions and goals without measures. A good plan lets you ask “how will we know it worked?” and find the answer in the document.

WORKED EXAMPLE
How the method behaves in a real situation.
A company wants to reduce billing delays. 5W2H defines an automated order check, the reason, deadline, owners, ERP location, validation method and cost. The outcome measure is the percentage of invoices issued on time—not merely the percentage of actions completed.
The example is intentionally specific. Numbers illustrate the reasoning and are not universal benchmarks: limits, scales and targets must be defined for the process being analyzed.04
MEASUREMENT AND INTERPRETATION
What to observe so the document does not become mere form filling.
Measures should serve reasoning. Whenever possible combine outcome, process and contextual evidence. For time series, look for patterns and variation rather than only point-in-time before/after comparisons.

Consistency test
Ask whether another person, using the same definitions and evidence, would reach a similar interpretation. If the answer depends heavily on individual judgment, refine the operational definition, scale or data source.
05
LIMITATIONS AND GOVERNANCE
The tool supports decisions; it does not replace judgment, context and validation.
Widely used management heuristic. Useful for structuring decisions, but not by itself a causal model or scientifically validated scale.
5W2H organizes execution but does not identify root cause or prove effectiveness. Actions should derive from diagnosis and end in outcome measures.
Define an owner, review frequency, official data source and condition for reopening the decision. Link actions to deadlines and indicators, hypotheses to tests, and risks to treatment and follow-up.
