Method Selection
No single method fits every case. We choose for yours.
Using the same tool for every problem is why so many investigations stop short. We look at what happened, what evidence exists and what is at stake, then combine the two or three methods that will actually answer your questions.

Why the choice matters
The wrong tool gives a confident wrong answer.
A fishbone cannot show sequence, and a timeline cannot show why a defence decayed.
Combining methods gives each finding two independent lines of support.
Every plan ends in the P3i Causation Model, so causes always reach a control gap.
Use it for
Planning any serious investigation
Reviewing why past investigations stopped short
Building an investigation standard
On its own it cannot
Replace evidence
Be decided by habit or a template
Method names are given for reference. Several are proprietary or trademarked; P3i selects the approach that suits each case and does not claim licensed certification in proprietary methods.
Not sure which method your case needs? A first call costs nothing, and we will tell you.
The P3i approach
How we investigate with the right method. Fact-finding, not fault-finding.
Every P3i investigation is led by a senior investigator and supported by internationally qualified process specialists. You will not receive a list of people to blame, or a long list of generic actions. You will receive the facts, the proven causes, and a short plan that closes the gaps, in this case and across your system.
Independent
No products, repairs or contracts to sell you afterwards.
Senior-led
Thirty years of investigation, from the first call to the final briefing.
Beyond the event
Process specialists find the other cracks before they fail.
Ready to present
Written for boards, buyers, insurers and regulators.

Questions
What investigation leads ask about choosing methods.
Why not use one method for everything?
Because each method answers a different question. Relying on one means some questions are never asked.
How many methods does a case need?
Usually two or three, plus the P3i Causation Model to reach the control gaps.
Are proprietary methods required?
No. We use recognised approaches suited to the case and do not claim licensed certification in proprietary methods.
Can you set a standard for our company?
Yes. We can help you define which methods your teams use for which types of event.
Right methods. Real causes.
