Weak Point Analysis

Weak point analysis furthers the development of a product by gathering information and analyzing weak points of previous products.
Thus it shows flaws and their origins in previous products and allows for quantitative deductions for future products.
It is important to differenciate between weak point analysis, the processing of complaints and the handling of mistakes with existing products.


  1. Define task: which product are the requirements or alternate solutions meant for? Which previous product or variant can be of use for the analysis?
  2. Identification of weak points: which problems or mistakes have occurred? In what way? Possible aspects: economical or technical aspects, quality, logistics, ...
  3. Identification of cause: isolation of activities or elements that are believed to be the reason for the weakness
  4. Analysis of cause: analysis of the elements' influencing factors or the activities' paramters. Possible starting points: interface, method, authority, working materials, time, space, reason.
