Key benefits of evidence‐based decision making

Effective decisions are based on the analysis of data and information. Other performance statistics or indicators, such as timeliness and conformance to the specification, user satisfaction survey results and supplier performance records should also be collected in the data and analysis process.

The information generated by the quality management system must be analysed; see data analysis and statistical process control (SPC). Key benefits of evidence‐based decision making include:

  1. Improved decision-making processes;
  2. Improved assessment of process performance and ability to achieve objectives;
  3. Improved operational effectiveness and efficiency;
  4. Increased ability to review, challenge and change opinions and decisions;
  5. Increased ability to demonstrate the effectiveness of past decisions.

Actions you can take enhance evidence‐based decision making:

  1. Determine, measure and monitor key indicators to demonstrate the organization’s performance;
  2. Make all data needed available to the relevant people;
  3. Ensure that data and information are sufficiently accurate, reliable and secure;
  4. Analyse and evaluate data, and information using suitable methods;
  5. Ensure people are competent to analyse and evaluate data as needed;
  6. Make decisions and take actions based on evidence, balanced with experience and intuition.
