Cost of quality training is for organizations that want to translate their quality and improvement work into financial language.
The obstacle quality units most often run into is not technical but financial: an improvement proposal finds no traction in the budget meeting, because the cost of the current situation cannot be shown.
The cost of quality approach closes this gap. It makes visible what nonconformity actually costs the organization, and makes the return on prevention investments measurable.
Visible and invisible costs
Scrap and rework records are kept in most organizations. But these are the visible part of the iceberg.
In the invisible part there is: extra inspections, unplanned downtime, expedited shipments, additional inventory, management time spent on customer complaints, delayed collections, lost orders and reputational impact.
These costs don’t sit in a single account in the accounting system; they’re scattered across different line items. The purpose of this training is to gather these scattered costs and turn them into a management-ready table.
Who should attend?
- Quality managers and quality engineers
- Production and operations managers
- Cost accounting and finance teams
- Continuous improvement teams
- Middle managers who need to defend business cases
There are no prerequisites.

Frequently Asked Questions
Our accounting system doesn’t make this distinction — can we still apply it? Yes. In most organizations the data exists but is scattered. The approach is built on reclassifying existing records; it doesn’t require a new accounting system.
What percentage of revenue should the cost of quality be? It varies by sector and maturity. What genuinely matters is not the absolute ratio but your own trend and the balance between categories.
Is this an audit requirement? Management system standards expect performance evaluation; the cost of quality is a strong tool for making it concrete. In automotive, the relevant CQI guideline is also referenced.
Can it be applied in the service sector? Yes. The categories are the same; the elements are defined according to service processes. Equivalents such as repeated transactions instead of rework, or cancelled services instead of scrap, are used.
