Company A is well aware of formal cost of quality methods and it has clearly determined its CoQ definitions. It knows exactly what are its conformance and non-conformance costs; however, it struggles to find out the shape of its CoQ curves, and hence, an optimum CoQ tactic. The search for an optimum CoQ is difficult because the business cycle changes often (every 2 years or less); product lines are released in phases, and component obsolescence and multiple engineering changes are quite common. Every change causes a new search for an optimum CoQ; moreover, different product lines require separate review, and variable volumes reduce optimization opportunities.
