ISO/IEC 20000 Introduction — Lesson 4: Performance Evaluation, Internal Review, Nonconformity, and Continual Improvement

Learning Objectives

• Interpret the requirements, principles, roles, and dependencies shaping performance evaluation, internal review, nonconformity, and continual improvement.
• Apply a practical workflow and create a reviewable SMS performance improvement plan.
• Evaluate the exception where performance measures do not support improvement priorities and determine proportionate follow-up.

Detailed Topics

• Performance Evaluation applied to the course scenario and expected evidence.
• Internal Review applied to the course scenario and expected evidence.
• Nonconformity applied to the course scenario and expected evidence.
• and Continual Improvement applied to the course scenario and expected evidence.

Instructor Demonstration

The instructor traces a case involving an IT service provider aligning support, change, supplier, availability, and customer reporting practices. The demonstration links decisions to objective evidence, records the result in SMS performance improvement plan, and tests the condition where performance measures do not support improvement priorities.

Hands-On Exercise

Complete a controlled exercise covering Performance Evaluation, Internal Review, Nonconformity, and Continual Improvement. Confirm scope and responsibilities, examine the stated exception, reach a supported conclusion, and preserve the outcome in SMS performance improvement plan.

1. Define the objective, boundaries, stakeholders, criteria, and expected work product.
2. Perform the activity while recording assumptions, observations, evidence, and decisions.
3. Test normal operation, the exception, and an escalation or follow-up condition.
4. Document conclusions, owners, deadlines, verification methods, and review triggers.

Scenario Analysis

• Identify the requirement or control with the strongest influence on the scenario outcome.
• Compare two defensible responses and explain their risk, operational, and evidence trade-offs.
• Decide how the SMS performance improvement plan should be approved, retained, reviewed, and updated.

Troubleshooting Guidance

Start where expected practice and observed evidence first diverge. Separate a missing record from an ineffective process, distinguish unclear ownership from a control failure, and treat “performance measures do not support improvement priorities” as a hypothesis until tested against the applicable criteria and intended outcome.

Validation Checklist

• Scope, roles, criteria, stakeholders, dependencies, and intended outcomes are explicit.
• The SMS performance improvement plan connects conclusions to objective, reviewable support.
• Normal operation, the stated exception, escalation, and follow-up were evaluated.
• Owners, due dates, verification methods, review triggers, and improvement actions are clear.

Lesson Outcome

Learners can apply Performance Evaluation, Internal Review, Nonconformity, and Continual Improvement, explain the reasoning used, and defend the result through SMS performance improvement plan.
