Figure 4.32 Example of a validation and testing process

The testing process is shown schematically in Figure 4.32. The test activities are not undertaken in a sequence. Several activities may be done in parallel, e.g. test execution begins before all the test design is complete. The activities are described below.

Validation and test management

Test management includes the planning, control and reporting of activities through the test stages of Service Transition. These activities include:

• Planning the test resource s
• Prioritizing and scheduling what is to be tested and when
• Management of incident s, problem s, errors, non-conformances, risks and issues
• Checking that incoming known error s and their documentation are processed
• Monitoring progress and collating feedback from validation and test activities
• Management of incidents, problems, errors, non-conformances, risks and issues discovered during transition
• Consequential changes, to reduce errors going into production
• Capturing configuration baseline
• Test metrics collection, analysis, reporting and management.

Test management includes managing issues, mitigating risks and implementing changes identified from the testing activities as these can impose delays and create dependencies that need to be proactively managed.

Test metrics are used to measure the test process and manage and control the testing activities. They enable the test manager to determine the progress of testing, the earned value and the outstanding testing, and this helps the test manager to estimate when testing will be completed. Good metrics provide information for management decisions that are required for prioritization, scheduling and risk management. They also provide useful information for estimating and scheduling for future releases.

Plan and design test

Test planning and design activities start early in the service lifecycle and include:

• Resourcing
• Hardware, networking, staff numbers and skills etc. capacity
• Business/customer resource s required, e.g. component s or raw materials for production control services, cash for ATM services
• Supporting service s including access, security, catering, communications
• Schedule of milestones, handover and delivery dates
• Agreed time for consideration of reports and other deliverable s
• Point and time of delivery and acceptance
• Financial requirement s – budget s and funding.
