After the root causes of a problem are identified, investigate methods to fix the problem. Evaluate several approaches to solve the problem. A thorough analysis of different approaches to eliminate a root cause is a critical part of the problem solving process.
The first approach to generate alternate solutions is to develop a cause and effect diagram. The team should brainstorm solutions. One alternative is to redesign the part or the manufacturing process. This approach should eliminate an opportunity for a problem to recur.
Communicate closely with the customer. How the root cause is eliminated might impact the customer in some unforeseen way. Customers should have a chance to input their needs into the problem solution.
