Diagnosing Snap-Fit Problems

Understanding failure modes and their relationship to the most likely root causes can help with a quick and accurate diagnosis. This minimizes the cost and time impact but it also helps ensure that the proposed changes will indeed fix the problem. Nothing is worse than making changes to a product and finding that the problem still exists or has even gotten worse. (Yes, this does happen.) Accurate diagnosis is particularly valuable during product development when prototype testing may indicate the need for improvements, yet time and cost constraints limit the available options.
