Technology User Needs Assessment, TUNASS®

The Technology User Needs Assessment is a front-end design analysis technique. This methodology enables you to include in your project at an early stage all relevant themes relating to the Human Machine Interface and functionality to promote greater ease of use, health and functional efficiency.

The working environments and systems under consideration for application are Critical Human Machine Interfaces (CHMI).
In practice, ergonomics and many aspects of layout are often only considered towards the end of a project. This is a missed opportunity as it leads to a suboptimal design and thus a poorly functioning layout or working environment. And the dissatisfaction of end users.

To support this type of design projects for Critical Human Machine Interfaces, we developed the TUNASS® methodology.

Application of TUNASS® at an early stage prevents nasty surprises later on

Our ‘Technology User Needs Assessment’ (TUNASS®) methodology enables project managers to focus closely – at every project phase – on systematically realizing the intended functionality and ensuring the comfort and well-being of the user.

The method encompasses ‘Tools & Techniques’ to facilitate timely agreement on the suitable design, head off problems before they arise and arrive at a plan of action. TUNASS® ensures that this operational philosophy is then systematically implemented in the design process, resulting in a functional design. By applying TUNASS® within the project, HTDS Consultants function as the link between the designing party and future end users at every project phase.

TUNASS® is based on international and national standards and regulations and on more than 18 years of hands-on experience in (re)design projects.

TUNASS® design methodology for:

  • Realization of operations-centred design – how it's meant to be
  • Efficient Modus Operandi – reflecting current trends
  • High degree of functionality and operator acceptance

TUNASS® is based on front-end engineering principles:

  • Early signalling and handling of dilemmas and subjects for discussion
  • Shorter project lead times
  • Fewer meetings required



TUNASS® benefits:

  • Functional design that reflects the operating philosophy and operational process
  • Focused end-user participation leads to broad-based support
  • Facilitation of a multi-disciplinary design team leads to a better result
  • Fewer recovery actions required after project

TUNASS® integration leads to:

  • Increased project and operational performance
  • Higher degrees of functionality, health and safety
