5W1H Analysis Template

What is a 5W1H analysis?

A 5W1H analysis is a systematic way to describe and diagnose a problem by asking six questions about it: What, Who, Where, When, Why and How. The framework dates back to the early twentieth century and endures because it forces you to look at a situation from more than one angle before drawing conclusions. It is a close relative of the 5 Why, the 4W1H and the 5M1E methods. Used well, a 5W1H analysis turns an event you have only partially understood into a description of the problem that is both complete and specific. In an inspection or compliance setting, it is most useful once facts have been gathered but before actions have been decided upon.

Why use a 5W1H analysis?

Problems tend to be examined from one angle at a time. Someone asks what happened; someone else asks who was involved; the cause is discussed separately. A 5W1H analysis presses the same subject through six different lenses, which is what distinguishes it from a straightforward incident report. Its second strength is that it separates description from decision. The descriptive sections establish What, Who, Where, When, Why and How. The later sections then record the action you intend to take. This keeps the record auditable: a reader can see what the facts were and what was done in response to them.

What a good 5W1H analysis covers

The checklist groups the work into stages. **Setup.** Record who conducted and prepared the analysis, the location, and the real start and end dates. These place the analysis in a verifiable context. **The six dimensions.** Each has a guiding question and a free-text answer field. The questions cover the situation, the people involved or affected, the location or context, the timeframe, the root causes and contributing factors, and how the process was carried out. **Actions & Follow-up.** Every action is typed and prioritised before it is closed. The action types are **Corrective Action**, **Preventive Action**, **Issue Report**, **Process Improvement** and **No Action Needed**. Each entry also carries a priority level and a description of the corrective action, solution or issue being reported. **Summary.** A short set of key findings, a count of the number of actions identified, supplementary recommendations and notes, a signature, and the finished-at time.

How to carry out a 5W1H analysis

Work through the six dimensions in order, writing a full answer to each before moving to the next. The What, Who, Where and When answers provide the descriptive base; the Why and How answers interpret it and point towards action. Once those are complete, move to the Actions & Follow-up stage. For each action you intend to take, choose a type from the five options, assign a priority level, and describe the action itself. This is the point at which the analysis stops being a description and starts becoming a record of change. Finish by writing a brief summary of the key findings, counting the actions you have identified, and adding any supplementary recommendations. A signature and the finished-at time close the record.

Frequently Asked Questions

Any situation that needs to be understood rather than merely fixed: a recurring defect, a delayed project, a safety incident, a process breakdown, or a decision one team must align around. Because it documents five distinct angles plus an explicit root-cause question, it suits operational, quality, project, and administrative teams, and anything from a single inspection finding to a full after-action review.

No single formula, but a complete pass records concrete answers for What, Who, Where, When, Why and How; distinguishes the immediate event from its underlying cause; links every finding to a typed, prioritised action; and closes with a short findings summary and any supplementary recommendations. The template also captures who conducted and prepared it, the location, and start and end times, so the record stands on its own.

Keep them separate. The What, Who, Where, When, Why and How answers describe the situation as it is. The Why and How sections then feed the Actions & Follow-up stage, where each entry is typed and given a priority. The setup prompts are kept distinct from the analysis itself. This separation makes the analysis dependable and the follow-up auditable.

Any correction that does not change the underlying cause leaves the problem free to return. 'Why' is the only one of the six angles aimed directly at cause, and 'How' is the only one that tests how the process actually ran. Answering both honestly is what turns the other four from a description into a diagnosis, and it is what makes the actions that follow proportionate to the finding.

Yes. Answer every dimension at the level of detail the situation deserves, log issues and supplementary recommendations where they belong, and confirm the relevant people have seen the analysis. At its most involved, the framework has been used as a '5M1E' or '4M1E' analysis for manufacturing and operational problems, where the six questions are asked of each factor individually. The '5W1H' label is just one of its names.

Pick the template that matches the problem. '5W1H' tells you what happened and why; '4W1H' and '5W1H' both reduce to the same six prompts. '5 Why' is a narrower root-cause technique. '5M1E' or '4M1E' extend the same logic across machine, method, material, measurement, man and environment. In short, '5W1H' is the more thorough of the descriptive frameworks and is the one to start with when the situation itself is not yet clear.

A 5W1H analysis is not a certified method, so it does not use a scoring model. What makes it useful is that the answers are specific and the actions are explicit. Some organisations also map the output onto an existing method — 5 Why for deepening the cause, a fishbone exercise for broadening it — but the discipline of a complete written pass is the part that does the work.
