Six Sigma projects

We can speed up the projects by plucking the low hanging fruits and then taking action on the FMEA items as quickly as possible.

Girish,You speed projects up most significantly by giving a clean project to a BB or GB. If you give then some idea and then they have to develop the problem into a project then it drags out. Worse, you have them find their own projects.Setting some random target is a pretty poor idea. Assuming all projects are the same is even worse. There are types of projects and they take different time lines. I think you can find something in Deming’s 14 points on setting goals like this.If you don’t understand project stratification how do you manage the project pipeline?Just my opinion.

Hi,
My experience is that you should scope the project (GB/BB) as small as possible. I use the similarity of “how do you eat an elephant?” “By small portions”.
It is better to solve a part of a big problem is a short period of time (3-4 month) instead of working on a big issue for long time (9+ month).
The question is how to scope it. First it is important to discuss it your champion. Often it takes some more data collection and a brainstorming with the team to have a clear Pareto of the biggest possible causes. Focus then on the 1st or 1st+2nd biggest ones. You should even create a sub-charter for that. Carry out the DMAIC, and continue with the next biggies from your first Pareto. By doing so, you will keep the motivation of you and your team high. You also quickly deliver results for the company. At the end you have solved the big project.
I  hope this helps.
PS:> One thing left: keep communicating with your champion and steering committee about how you tackle the big issue, otherwise they will have a false expection because they expect you to solve their biggest problem in a few month time.
