En projektkontrakt (Project Charter) er en aftale mellem en projektsponsor og projektteamet, der definerer forbedringsproblemet, det tilsigtede resultat, scope og bemyndigelse til at udføre et Lean Six Sigma-projekt.
During DMAIC's Define phase, the charter establishes why the work merits resources and what the team is accountable for delivering. It identifies the sponsor and project leader, sets boundaries around the process, and states a measurable goal. Approval gives the team a shared basis for resolving scope disputes. A charter should leave room for investigation rather than commit the team to an untested solution.
For eksempel kunne en projektkontrakt for fakturabehandling foreslå at reducere den gennemsnitlige sagsbehandlingstid fra 12 minutter til 9 minutter pr. faktura inden for fire måneder, samtidig med at den eksisterende fejlmængde opretholdes. Scope kunne dække indenlandske leverandørfakturaer og udelukke omtvistede betalinger. Measure-fasen vil teste, om baseline og fejldefinitionen understøtter det mål. Hvis empirien ændrer problemformuleringen, kræver den reviderede projektkontrakt sponsorens godkendelse og en registrering af årsagen.
The charter frames the work documented in an A3 problem-solving account. A SIPOC helps clarify its process boundaries, while Voice of the Customer work informs the requirements behind its goal. The Styringsplanen assigns monitoring and response responsibilities after implementation. In a project portfolio, the approved charter establishes the original commitment against which reviewers can assess delivered results.
