ISO/IEC 20000 Lead Auditor Training — Lesson 3: Service Portfolio, Relationships, Resolution, Control, and Findings

Learning Objectives

• Interpret the principles, requirements, roles, and dependencies shaping service portfolio, relationships, resolution, control, and findings.
• Apply the workflow and produce service-practice evidence and finding matrix that another practitioner can review.
• Analyze “service targets are met while repeated disruptions affect customers” and recommend a proportionate, supported response.

Detailed Topics

• service portfolio
• service levels
• supplier management
• incident management
• change management
• configuration management
• service reporting
• finding classification
• Competence, communication, governance, documented information, risk, validation, and follow-up considerations

Instructor Demonstration

The instructor demonstrates the service portfolio, relationships, resolution, control, and findings workflow, identifies the applicable inputs and responsibilities, records checkpoints in service-practice evidence and finding matrix, and contrasts the accepted state with a condition where service targets are met while repeated disruptions affect customers.

Hands-On Exercise

Complete a controlled implementation, audit, assessment, or foundation exercise for Service Portfolio, Relationships, Resolution, Control, and Findings. Establish scope and criteria, collect or create evidence, examine “service targets are met while repeated disruptions affect customers,” reach a supported conclusion, and preserve the result in service-practice evidence and finding matrix.

1. Confirm objectives, scope, roles, criteria, stakeholders, and expected outputs.
2. Perform the planned activities while recording assumptions, evidence, and decisions.
3. Test a normal case, an exception, and a follow-up or improvement condition.
4. Document conclusions, owners, due dates, escalation, and verification requirements.

Scenario Analysis

• Identify the requirement or principle with the strongest influence on service portfolio, relationships, resolution, control, and findings.
• Compare two defensible responses and explain their governance, risk, and evidence trade-offs.
• Determine how service-practice evidence and finding matrix should be approved, retained, reviewed, and updated.

Troubleshooting Guidance

Separate missing evidence from ineffective practice, and distinguish a documentation issue from a control, process, governance, or competence failure. Use service-practice evidence and finding matrix to trace the earliest divergence. Treat “service targets are met while repeated disruptions affect customers” as a hypothesis until the response is validated against the applicable requirement and intended outcome.

Validation Checklist

• The scope, criteria, stakeholders, and intended outcome for service portfolio, relationships, resolution, control, and findings are explicit.
• The service-practice evidence and finding matrix links statements and decisions to objective, reviewable support.
• Responsibilities, competence, communication, risk, legal duties, and change impact were considered where relevant.
• Findings, corrective actions, monitoring, review triggers, and improvement ownership are clear.

Lesson Outcome

Learners can apply Service Portfolio, Relationships, Resolution, Control, and Findings, explain the reasoning used, and defend the result through service-practice evidence and finding matrix.
