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.

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.
PDC-03How can PDCA cadence govern a project without confusing task progress with project outcomes?
Projects turn intention into deliverables under constraints of time, resources, scope and risk. Documentation should facilitate decisions and governance rather than merely record what happened afterwards.
Use it when there are deliverables, owners, dependencies, milestones, acceptance criteria or a need to track evolution objectively.
02
METHOD ARCHITECTURE
Technical construction: from operational definition to evidence.
An improvement cycle creates temporal discipline: plan with a hypothesis, execute under control, observe effects and decide the next move. Closing the cycle should produce reusable knowledge, not merely confirmation that a task was completed.
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.
Compare what was observed with what was expected. Record deviations, test conditions, data and the rationale to adopt, adapt, standardize or test again.
03
WORKED EXAMPLE
How the method behaves in a real situation.
In a migration project, Plan defines deliverables and criteria; Do records hours and milestones; Check compares progress, defects and risks; Act replans or standardizes. A project that is 90% complete may still be critical if the remaining 10% is data migration.
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.
Operational adaptation of recognized methods. Consistency depends on explicit definitions, criteria, evidence and governance.
Completion percentage should be weighted by deliverable or effort; a simple task average can create false progress.
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.
