Root-cause assessment
Evidence-based analysis with clearly documented findings.
Root Cause Analysis & 8DUnderstand the cause.
Understand the cause.
Strengthen the response.
Recurring issues need an investigation that connects evidence to action. PTS supports teams in defining problems, examining causes and documenting corrective actions through a structured RCA or 8D process.
From issues to lasting
improvements.
improvements.
A structured route from issue to action.
Typical situations include recurring quality defects, process deviations, documentation-related errors, customer concerns and incomplete corrective-action records. We assess each issue against the evidence, expertise and access needed for a useful investigation.
- 01
Define
Clarify the problem, scope and impact.
- 02
Contain
Record short-term actions to limit further impact.
- 03
Investigate
Analyse data and identify potential causes.
- 04
Correct
Select actions that address verified causes.
- 05
Verify
Review effectiveness and capture learning.
Key deliverables.
Clear, structured outputs to support consistent resolution, communication and improvement.
Corrective action plan
Practical actions with owners and timelines.
8D report
A complete, structured record of the 8D process.
Effectiveness review
Assessment of results and recommendations for improvement.
What we need from your team.
Issue history, applicable requirements, defect or process data, inspection or test results, previous actions and access to relevant technical and process owners. Missing evidence and validation dependencies are documented explicitly.
Evidence
Relevant data, records, samples or failed parts, as available.
Issue history
Background, previous occurrences and prior analysis.
Process context
Details of processes, systems and relevant changes.
Common questions
Can you guarantee that an issue will never recur?
No. We support evidence-based investigation and verification; outcomes depend on the cause, implemented actions and operating conditions.
Who approves and implements actions?
The customer’s authorised owners approve operational changes and implement actions unless the contract assigns particular activities to PTS.
Let’s solve it together.
Share a few details about the issue and your investigation requirements.
Investigation methods and agreed deliverables
Our investigation approach
Define the problem. Establish what happened, where and when it occurred, the affected scope and the measurable gap from the requirement.
Support containment. Record immediate actions, owners and checks to reduce further impact while the investigation continues.
Examine potential causes. Use methods such as 5 Whys, fishbone analysis or fault-tree analysis where appropriate. Distinguish hypotheses from causes supported by evidence.
Verify causes and select actions. Agree the checks needed to test the proposed root cause and evaluate whether corrective actions address it.
Review effectiveness. Assess agreed evidence over an appropriate observation period and record remaining risks, prevention actions and lessons learned.
What you receive
Depending on scope, deliverables include the problem statement, evidence register, cause analysis, containment plan, corrective-action register, 8D report and effectiveness-review record.
