Then, when problems do occur, we know exactly what steps to take to help ensure that our solution really will “make it go away.” While there are different variations to an SPS (, etc.), they all follow the same basic steps. Define the Problem It is important to write a problem statement that is easily understood and is stated purely in terms of measurable or observable symptoms.
At this point, there should be no mention of suspected causes or possible solutions. A good problem statement might look something like this: “High (greater than 8 ppb) trace metals in one of our hardmask products are causing unacceptably high defect counts with our most important customer.
You then analyze the problem once uncovered, discuss it, and write a Standard Operating Procedure (SOP) to eliminate this from happening in the future.
Example number II: A bicycle fender is very difficult to put into a plastic sleeve because of the contour of the fender.
First you define the problem, next you measure it, then analyze it, improve it, and the final step is to control/maintain the solution. Once you find the root cause of the problem and solve it, it must be controlled so it does not occur again.
In both of these methods finding the root cause of the problem and solving it is at the core of problem solving.We can test our theory by making a new batch with everything the same except for a new batch of the suspect ingredient.If the defect levels are back to normal, that’s a good indication that we have confirmed our root cause. Implement Solution After we’ve identified the root cause, we implement a solution to remedy the issue, standardizing our solution and making the change permanent.We will lose this business if we cannot correct the problem by the end of the year.” 2.Describe the Current Situation We do this by examining data that is readily available.This way you can get comfortable with the steps before you use them with more complex problems.Six Sigma Quality uses DMAIC: Define, Measure, Analyze, Improve and Control as their driving problem solving steps guide.By taking the steps above, you may be able to reduce your level of stress and maximize your effort in addressing problems in your life.As with any coping strategy, it is best to practice this skill first with a very basic or non-threatening problem.Did they all use the same lots of the raw materials?By identifying where the problem is occurring, and where it is not occurring, we begin to zero in on what is causing our problem. Identify Possible Causes To identify possible causes, we should gather the team and brainstorm all potential causes that come to mind.
