Defining Six Sigma Projects
Six Sigmaโs impressive bottom-line results normally flow from Six Sigma projects. Properly defined Six Sigma projects meet certain criteria:
Six Sigma Criteria
- They have clearly defined deliverables.
- They are approved by management.
- They are not so large that theyโre unmanageable nor so small that theyโre unimportant or uninteresting.
- They relate directly to the organizationโs mission.
The project definition is made explicit in the project charter, which is a document issued by senior management, usually the project sponsor (not the project manager or Black Belt), that provides the project manager with the authority to apply organizational resources to project activities. The Six Sigma project charter typically includes:
- A description of the business need addressed by the project (i.e., the opportunity or threat presented to the organization that provided the stimulus to undertake the project)
- The product that will be produced by the project, that is, characteristics of the value (product or service) that the project will create
- The relationship between the business need and the product. The product should be described at a high level, but with sufficient detail to support subsequent project planning.
- The authorization to apply organizational resources to the project
The problem statement answers the question โWhy is it essential that this project be done now?โ It should be specific enough to help the team identify the projectโs scope and major stakeholders. Although the project team will develop a work-breakdown structure that will break large projects into smaller subprojects, problems of gargantuan proportions should be subdivided into smaller projects before assigning them to Six Sigma teams. Senior leadership should put the problem statement in writing.
The Six Sigma project charter should include a statement indicating the mission of the project team and linking the project to the larger organizationโs mission via the charter. Avoid the following pitfalls in developing mission statements:
- The mission is unclear or undefined (e.g., “Get a team together to work in the shipping departmentโ).
- The mission is too broad (e.g., “Reduce customer complaintsโ).
- The problemโs nature and severity arenโt defined (e.g., “Are scratches really a big problem?โ).
- Projects have little or no affect on the organizationโs success. (Even if theyโre successful, no one will really care.)
- Missions overlap the missions of other teams (e.g., team Aโs mission is to reduce solder rejects, team Bโs mission is to reduce wave solder rejects and team Cโs mission is to reduce circuit board assembly problems).
- Projects improve processes that are already scheduled for extensive redesign or discontinuation.
- Missions cover a huge system (โpatient admittingโ) rather than a manageable process (โoutpatient surgery preadmissionโ).
- Missions focus on symptoms rather than root causes (e.g., โReduce touch-up of defective solder jointsโ instead of โEliminate wave solder defectsโ).
- Project deliverables are undefined (e.g., โStudy TQMโ rather than โReduce waiting time in Urgent Care to an average of 10 minutesโ).
The mission statements of various teams should identify the boundaries between them. Where confusion exists, project sponsors should meet to clarify responsibilities.
Six Steps in the Chartering Process:
- Obtain a problem statement.
- Identify the principal stakeholders.
- Create a macro flowchart of the process.
- Select the team members.
- Identify the training to be received by the team.
- Select the team leader.
Note that these steps are done at a high level. As the project proceeds, the project team will refine and elaborate on each of these items. The refinement will require frequent communication with the project sponsor. Project charter revisions must be documented and approved by the sponsor. Six Sigma project charters are formal documents that become part of the project plan.
