Effective participant recruitment is vital to collecting reliable data during usability testing of digital products and services. Not only should test participants reflect the characteristics of the targeted users of the product or service, but they must also be likely to use it. Only then will their experiences and opinions yield reliable data for identifying meaningful improvements.

Usability testing is a task-based process as well as a sampling process, this means we cannot test every possible task users can perform with a product. As UX practitioner we should structure tasks around business goals, product re-design and where applicable new features.
This episode is about the best practice to adopt when deriving tasks or formulating your tasks in preparation for a usability test.
It is very important to formulate actionable and reasonable tasks to avoid task misunderstanding.
