All of the "Belts" play various roles in the Six Sigma project. Green Belts and Black Belts are allowed to commence, expand and lead projects in their functional areas.
Green Belts are those employees who are trained to implement Six Sigma projects under the guidance of the Black Belts to achieve the desired goals. They carry out these activities along with their regular responsibilities. Green Belts spend around 25-50% percent of their time involved in the Six Sigma projects. They are aware of all the important activities that they have to carry out.
They should be able to explain the importance of the y=f(x) formula to the business and the processes. They are trained in the various tools needed to carry out the data collection and for validating the measurement system. They are also well-trained on DMAIC methodology and statistics.
The Black Belt coach imparts detailed instructions on the statistics and creation of histograms and pareto diagrams. This experience is valuable, and their prowess with Six Sigma methods helps them in getting promotions and incentives within the organization.
Upper management also reviews the Six Sigma Green Belts projects and provides the necessary feedback on developments and shortfalls in the project path.
Monitor Project Progress
Six Sigma Green Belts are selected by the management team to receive either Six Sigma online or classroom training, or a combination of both on Six Sigma methods, tools and techniques. However, the Six Sigma training they receive on these tools is generally less than what Black Belts receive. The Black Belts carry out cross-functional responsibilities.
Green Belts carry out the project for their own areas of operations. Each company has its own set of Six Sigma certification requirements, which may include the completion of Six Sigma online training, written or online exams and completion of a project. Green Belts may be given incentives by companies to complete a project or even Six Sigma certification.
However, another company most likely will not recognize the certification of one company. Some companies require one project to be carried out to maintain the certifications. They need to carry out meetings with Black Belt coaches to review the project progress and seek improvements.
With the Green Belts training, they are able to understand the benefits and gains out of the project success. They understand the relevance of the project to make the processes easier and the overall effect of it on the team and the organization as a whole.
Timely completion of the Six Sigma project is necessary before the tollgate review. Green Belts have to plan properly and stay in control of the progress of the project. The project should be strictly based on data; if Green Belt has no knowledge of finance, the Green Belt project will give them an opportunity to learn it, know about the issues faced by management, and to quantify the benefits.
Carry Out Tests
Six Sigma Green Belts know that tools exist, though they may not be using them. They will be able to calculate the average and standard deviation from the set standards of the various metrics; however, they are business professionals and not quality controllers. They will be able to carry out statistical tests using software such as Minitab and JMP.
Green Belts should be aware of the importance of preparing the Fishbone diagram to understand the basis of process defects. They will be able to help their bosses and co-workers by preventing defects. This will also help them in winning support for the Six Sigma project. Green Belts should be able to form a base for change with less resistance from co-workers, if they have shown visible improvements in the processes and the output.
Green Belts should start their projects only after top management commits to the necessary resources for improvement. They should share information with others above them, their co-workers and others who have a stake in the growth of the company.
These are a few things that the Green Belts should know. The list, though, goes on and on.
