Performance Testing Tasks

You are overseeing testing for an existing distributed system that manages inventories of automobile and light-truck tires across multiple warehouses nationwide. The system is being enhanced to track incoming restocking shipments at the warehouse entry point and outbound sales shipments at the warehouse shipment point, all performed in real time. System load has traditionally peaked on Mondays because of demand accumulated over the preceding weekend.

You are creating an operational profile that simulates entities submitting large bulk orders of greater than or equal to 1600 tires per transaction. You believe the profile accurately represents this type of power purchaser.

Which of the following steps must you take to ensure that your operational profile is accurate?

Explanation

Operational profiles should model expected real-world system use and be validated with the business and technical stakeholders who understand the relevant user segment. Reviewing and refining the power-purchaser profile with those stakeholders before testing confirms that its transaction volumes and behavior represent actual operational use. The ISTQB Performance Testing syllabus identifies analysis of operational profiles and performance objectives that meet stakeholder needs as core performance-testing activities.
