Format: Peer-reviewed article

Type: Research — Non-experimental

Experience level of reader: Fundamental

Annotation: Description of a design and evaluation process for a new device that integrates input from the intended users in all phases of the process. The article first identifies and scopes the problem, then reviews existing literature and proceeds directly to development and testing.

Setting(s) to which the reported activities/findings are relevant: Large business, Small business (less than 500 employees), University

Knowledge user(s) to whom the piece of literature may be relevant: Manufacturers, Researchers

Knowledge user level addressed by the literature: Individual

This article uses the Commercial Devices and Services version of the NtK Model

Primary Findings


  • User input involved an initial focus group to establish the development plan, consumer testing of the alpha prototype, and then again field testing of the beta prototype. All to ensure the device fully met the needs of the target audience.
    Paper describes device design, prototype construction and testing with consumers involved at all levels.
    Occurrence of finding within the model: Step 4.11, Step 6.3, Step 5.3
  • Systems for addressing the problem have been investigated widely in both commercial and research literature. The findings cover requirements for the general population as well as for the target user group. The presence of this body of knowledge provided sufficient basis for moving directly to development activity.
    Device design, development and testing project described in detail.
    Occurrence of finding within the model: Gate 2
