The level of quality improvement with six sigma methodology will vary with each organization that uses it. It has a goal of allowing only 3.4 defects for every 1 million items that are produced. This goal is not realistic for most manufacturers to achieve, but it is a good goal to strive for.
The secret to the six sigma methodology is in its approach to running a project. This methodology sets up systems within the many processes of a project so they can be self improving all the time. This constant evaluation of all the processes involves everyone in the project team. This makes it easier to notice when there is an area of the process that can be improved.
Not every process can always be improved upon each time it is reviewed. The six sigma methodology approach to running an organization knows this. It is also known that the large flaws in an organization will be dealt with when this approach to running an organization is initiated. This is when the largest leaps towards the goal of only having errors in your product to the 6 sigma level. The challenge is keeping the program going after this point in time.
Every little improvement, no matter how small, will make a positive contribution in your organization’s effort to reach the goals of the six sigma methodology. Constant and continuous evaluation is a must by all project team members. The longer this methodology is in place, the closer you will be to your goal. What is beneficial along the way of achieving this goal is that fewer and fewer errors and defects will be produced by your organization. This will make your organization more profitable in your efforts of reducing defects.
The six sigma methodology has been around for over 30 years now. Very few organizations have achieved the final goal of only having 3.4 defects per 1 million items. What has been achieved by those that use this approach to running an organization is an improvement in their process, which has translated to greater profits.
