What Is Cost Of Quality (COQ): Cost Of Good And Poor Quality

This comprehensive guide defines COQ, delves into the costs associated with high and low quality, elucidates the method of computing the quality cost, provides real-world instances, and outlines strategies for improving quality to leverage COQ:

The intense global market makes quality offerings essential for the IT sector.

Recent times have seen IT becoming increasingly crucial in supporting businesses, necessitating executives to carefully evaluate its operations for additional value, such as improved profit margins, cost-saving in operations, expedited software product team, and more.

While delivering a completely defect-free product is not feasible, the goal is to reduce anticipated failures in functional and non-functional requirements to the barest minimum. Expectations can encompass both tangible and abstract properties. Therefore, it’s critical to set clear expectations.

Quality Cost Formula

COQ = Control cost + Failure of control cost or

COQ = Superior Software Quality Cost + Subpar Software Quality Cost

Superior Quality Cost (COEQ) = Prevention Expenditures + Detection Expenditures

Subpar Quality Cost (COIQ) = In-house Failure Charges + External Failure Charges

While attempting to achieve all quality aspects seems desirable, each assessment incurs more cost. Therefore, it is vital to find a compromise and vividly communicate the quality coverage to all stakeholders.

Striking a balance in quality management is crucial in prioritizing high-quality aspects achievable within a favorable budget.
