QuestionQ15

Create, deliver and support services

An internal service provider for a large retail organization is undertaking a major update to the self-checkout terminals used in its supermarkets. The update includes new hardware, software, and integration with a new card payment system.

How should the service provider make sure that the update is tested sufficiently?

  • A Delegate to the vendor testing of the terminals and the card payment system
  • B Include user experience and perception in the scope of testing and involve multiple teams
  • C Limit testing to the pre-agreed technical criteria and use a dedicated team of testers
  • D Focus testing solely on user experience and delegate it to operational teams
Explanation

Testing should involve multiple relevant teams and cover user experience and customer perception as well as technical functionality. A self-checkout and card-payment change is an end-to-end service change, so technical acceptance criteria alone do not adequately validate usability, operational readiness, or the customer impact.
