Back to Phase 2: Conceptual Design
Testing early and often is the most certain way to ensure the ultimately implemented solution completely meets your users’ needs. To that end, testing should commence as soon as concepts are ready.
Start validating with end users as soon as conceptual designs are mature enough to demonstrate their intent. With this type of testing, early beats late in terms of benefit. Since the conceptual phase typically revolves around exploring a range of solutions, this phase of testing functions well as a means of identifying “best of breed” ideas that warrant further pursuit.
