This lesson examines the quality management frameworks that are integrated into modern performance management systems. It covers Total Quality Management, Six Sigma, and the Cost of Quality framework, all of which are specified in the US CMA syllabus and represent essential knowledge for management accountants .

• The Link Between Quality and Performance Management: Quality management is an integral part of performance management because it directly impacts customer satisfaction, operational efficiency, and profitability. The US CMA syllabus specifically includes “Quality management: TQM, Six Sigma, cost of quality” as part of the Performance Management section .

• Total Quality Management (TQM): TQM is a management approach to long-term success through customer satisfaction. It is based on the participation of all members of an organisation in improving processes, products, services, and the culture in which they work. TQM focuses on continuous improvement, process management, and customer focus.

• Six Sigma: Six Sigma is a set of techniques and tools for process improvement that aims to reduce the probability of an error or defect to 3.4 defects per million opportunities. It uses statistical methods and creates a special infrastructure of people within the organisation who are experts in these methods. Six Sigma projects follow a defined sequence of steps with quantified financial targets, often using the DMAIC (Define, Measure, Analyse, Improve, Control) methodology.

• Cost of Quality (COQ): This framework categorises quality-related costs into four groups:

  1. Prevention Costs: Costs incurred to prevent defects (e.g., training, quality planning, process improvement).

  2. Appraisal Costs: Costs incurred to detect defects (e.g., inspection, testing, quality audits).

  3. Internal Failure Costs: Costs resulting from defects discovered before delivery to the customer (e.g., scrap, rework, downtime).

  4. External Failure Costs: Costs resulting from defects discovered after delivery to the customer (e.g., warranty claims, returns, lost reputation).

  • By understanding these costs, organisations can make informed decisions about investments in quality improvement programmes, aligning quality management with financial performance.
