User manual

A field guide to running a DMAIC project end-to-end.

Define

Lock in the problem statement, scope, and team before you touch data.

Charter
Open the assignment, switch to the Charter tab, and fill the seven panes (Team, Overview, Drivers, Leverage, Risks, Stakeholders, Schedule). The header progress bar tracks how complete the charter is.
Schedule
Add DMAIC milestone dates beneath the charter. The schedule rolls up into the executive summary on the report.
VOC + CTQ
Capture customer voices (VOC) and translate each into a measurable CTQ with target + spec limits.

Measure

Map the process and put numbers on it.

Process detail
Add a process row, set its lower/upper spec, and either type measurements directly or import from Excel/CSV (one column per process).
SIPOC + VSM
Use SIPOC for high-level scope; switch to VSM when you need step-level cycle/wait times. The VSM efficiency tile turns red below 25%.
Live shadowing
Open a shadowing session to time real work in the field. The "End step + start next" button commits an observation; "Wait/blocked" tracks idle time.

Analyze

Find the vital few from the trivial many.

Capability charts
With ≥ 8 raw measurements you get the full pack: histogram with normal overlay, I-chart with control limits, and a sigma-level gauge.
Run / box / scatter charts
In the Toolkit, run-chart shows Nelson rule violations; box plot shows whiskers and outliers; scatter shows the fitted regression line.
Fishbone & 5-Whys
Hypothesise root causes by category (people, process, equipment, materials, environment, management) and drill with 5-Whys.
FMEA
Score Severity / Occurrence / Detection — the system computes RPN and flags the top items.

Improve

Pick solutions and pilot them.

Recommendations
Track each improvement from Proposed → Approved → Implemented; tag difficulty so leadership sees the lift.
Solution selection / Cost-benefit / PICK matrix
Toolkit entries that quantify trade-offs. Pin the winning analysis with the "Pin to report" toggle.
Piloting + Poka-Yoke
Document the pilot plan and any error-proofing you put in place.

Control

Hand it back to the operators with guardrails.

Control plan + Response plan
Spell out the metric, target, and the action when the metric drifts. Response plans surface in the report appendix.
SOP + Audit checklist
Keep a single source of truth for the new way of working and the audit cadence.
Report (HTML + PDF)
The report compiles charter, capability, pinned toolkit runs, recommendations, and any AI assessment. PDF rendering runs as a background job — the button shows progress and downloads automatically when ready.
