Traceable
Every transformation, judgement and exclusion should be explainable from source to result.
Methodology
Structured for governance. Adapted to the real question.
The method connects interpretation, evidence, analytical design, implementation and review. It does not imply a fixed duration or a one-size-fits-all sequence.
One chain of reasoning from requirement to controlled output.
Testable
Assumptions and controls are specified so reviewers can reproduce and challenge them.
Operable
Documentation, code and handover are designed for recurring use, not only initial delivery.
Six connected control points.
Use the tabs to inspect the principal output at each stage.
Requirement
Read the regulation and agree the interpretation in writing.
Output: Agreed scope and interpretation note
From the question to a maintained capability.
01 Frame Clarify the question, users, outputs and governance requirements.
02 Assess Review data, methods, tools, controls and model risk.
03 Model Prepare data, test assumptions and build transparent analysis.
04 Validate Challenge performance, stability, implementation and limitations.
05 Automate Add repeatable code, controls, reconciliation and logging.
06 Transfer Document, train, hand over and define monitoring.
Illustrative delivery sequence, not client data. Stages can overlap or be omitted where scope does not require them.
Review rights are part of the design.
Evidence boundaries
Source systems, permitted data, exclusions and reconciliation expectations are established before modelling. Sensitive material stays within the client’s approved environment.
Challenge and approval
Owners, reviewers and approval points are explicit. Limitations remain visible and material changes are versioned with their rationale.
The solution must remain understandable after delivery.
Handover can include model specifications, commented code, reconciliation checks, run instructions, monitoring guidance and working sessions. The exact package follows the agreed operating model.
Methodology questions.
Is every engagement six stages?
No. The stages are a control framework, not a fixed-duration package. Scope and sequence depend on the question, available evidence and governance requirements.
Can validation remain independent from development?
Yes. Roles, review rights and evidence boundaries are agreed during framing so independent challenge is not weakened by delivery pressure.
What is handed over?
The agreed combination of code, specifications, controls, documentation, monitoring guidance and working sessions needed to operate or review the solution.
Next step
Tell me what needs to run reliably.
A short brief is enough to establish whether this is a fit. Describe the situation in general terms only. Do not send client data or model files.
