Second level of certification in the 6 Sigma hierarchy, the Green Belt is in charge of piloting problem-solving projects using most of the statistics tools.
The function of the Six Sigma Green Belt
The Green belt works on smaller projects or under the responsibility of the black belts. Generally, budgets for Green Belt projects are from 30 000 to 80 000 $.
Part-time on these missions, the Green Belt has the role of:
- Drive problem solving projects.
- Define and manage projects
- Document and present the results.
The human qualities of the Green Belt
Methodical: The 6 Sigma consists of a multitude of tools that all have defined processes… and not at random. Reversing or forgetting steps can lead to the failure of the project.
Spirit of Synthesis: situations are often complex, in order to avoid getting lost in the workings of change and problem solving, hindsight and the ability to synthesize is necessary.
simplicity and pugnacity: These are attitudes often cited as essential to facilitate contact and achieve adherence to these ideas.
Perfectionist : seeking Perfection is the ultimate goal of the process and projects.
The components of the Green Belt training
In addition to knowing at a higher level the knowledge of the Yellow Belt, the Green Belt is formed on the elements below.
For the levels, the scale is as follows:
- E: Expert, knows how to use and transmit
- C: Good knowledge, knows how to use
- I: understands what it is but not or little use it
