Map the Current-State Process
2–3 weeks (2 hrs/day)
Select a real process with at least three handoffs between people or systems. Map the full current state using BPMN or swimlane notation, documenting every step, decision point, and handoff. Verify the map against reality by walking through it with at least one person who executes the process and correcting any discrepancies.
Proof required
Submit: the current-state process map in BPMN or swimlane notation; a scope document stating the process boundaries, how many people were interviewed or observed, and the total cycle time documented; and a verification note from at least one process participant confirming the map reflects how the process actually runs.
What gets checked
- Map shows all decision branches and what triggers each path — not a linear flow pretending the process never varies
- All handoffs between people or systems are explicitly labelled with the hand-off mechanism (email, ticket, verbal, etc.)
- At least one process participant has confirmed the map is accurate — desk-based mapping without validation is not sufficient
Common mistakes
- Mapping the process as it should work rather than as it actually works — the improvement analysis will then address phantom problems
- Using vague swim lane labels ('Team A', 'System') instead of specific roles and system names

What a verifier looks for
- Pick a decision point on the map and ask: 'what actually happens when condition B is true?' — does the map show it?
- Check that handoff mechanisms are specific: 'email to manager' rather than just an arrow
- Ask to see the verification note — was it written by someone who actually executes this process, not just their manager?
- Challenge the cycle time: ask how the total time was measured and whether it is the median or the exceptional case
Identify Waste and Root Causes
2–3 weeks (2 hrs/day)
Apply a waste-identification framework — Lean's eight wastes, value-stream mapping, or a similar method — to identify the bottlenecks, rework loops, and non-value-add steps in the mapped process. Perform a root cause analysis on the two highest-impact waste sources using 5-Whys or fishbone diagram, going at least three levels deep.
Proof required
Submit: the annotated process map with waste categories clearly marked and the value-add versus non-value-add classification for each step; root cause analysis documents for the two highest-impact waste sources (5-Whys or fishbone diagrams going at least three levels deep); and a confirmation note from a process participant that the waste identification is accurate.
What gets checked
- Waste identification is confirmed by at least one process participant — not desk analysis alone
- Root cause analysis goes at least three levels deep for each waste source — not stopping at the first symptom
- Evidence (observation, time measurement, error log) is cited for each waste identified
Common mistakes
- Identifying waste through assumptions rather than observation — the 'obvious' waste is often not the highest-impact one
- Stopping root cause analysis at the first level ('it takes too long because the approver is slow') rather than finding the systemic cause

Masteryfor the dedicated
What a verifier looks for
- Ask: 'how did you confirm this was actually the highest-impact waste?' — push for evidence, not intuition
- Walk through one root cause chain and ask 'why?' at each level until the analysis stops — does it stop too early?
- Check the evidence cited: is it quantified (time, error count, rework frequency) or just observed?
- Ask whether the process participants agreed with the waste classification or whether there was disagreement
Design Future State and Present to Process Owner
2 weeks (2 hrs/day)
Design a future-state process map that addresses the root causes identified, removing or redesigning the two highest-impact waste sources. Quantify the expected improvement conservatively. Present the current-state analysis and future-state proposal to the process owner or a lean/operations practitioner, and document their feedback.
Proof required
Submit: the future-state process map in the same notation as the current-state map; an implementation roadmap (steps, owners, timelines); a quantified benefit estimate with conservative and optimistic scenarios; and a written record of the review meeting with the process owner's specific questions and your responses.
What gets checked
- Future-state map directly addresses the root causes from m2 — not generic simplification
- Benefit estimate includes a conservative scenario grounded in the measured waste data, not aspirational targets
- Process owner has confirmed the future state is technically and organisationally feasible — not just theoretically superior
Common mistakes
- Designing a future state that assumes tools or changes that are not in the team's control to implement
- Presenting improvement estimates without showing how they were calculated from the waste measurement data

Masteryfor the dedicated
What a verifier looks for
- Check that the future state directly removes or redesigns the root causes from m2 — not just generic simplification
- Ask the candidate to walk through the benefit estimate: how was the baseline waste measured and how is the improvement calculated?
- Verify the process owner attended the review — a presentation to a peer or the builder's manager is not valid
- Ask whether the implementation roadmap assigns named owners or uses generic 'team' responsibilities
