What is Usability?

Usability engineering is an approach to product development that incorporates direct user feedback throughout the development cycle in order to reduce costs and create products and tools that meet user needs.

Two international standards define usability and human-centered (or user-centered) design:

"[Usability refers to] the extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of user." - ISO 9241-11

"Human-centered design is characterised by: the active involvement of users and a clear understanding of user and task requirements; an appropriate allocation of function between users and technology; the iteration of design solutions; multi-disciplinary design" - ISO 13407

NTS consciously works towards making its deliverables more usable.

Usability: Solution to a Problem
NTS detects the most common causes of problems in software development that are :
Technical developers are adept at understanding technical issues and, therefore, focus on what software should do rather than how the user will employ it.

Users' knowledge, skills and objectives often differ from technical developers' and, therefore, confuse their struggle with the software.

Usability Testing Services

Our designers offer a comprehensive range of usability testing services utilising the latest industry best practices, which include:

GUI Design Lab
Following the completion of usability testing, GUI Designers prepare a report that details our findings and provides recommendations on how to improve your user interface. NTS not only provides consulting, but also provides alternative design alternatives wherever required.

The guiding principals of Usability Design are a function of the changing times. Especially true for the web-based products, where we constantly update ourselves with user surveys conducted by authoritative agencies like GVU's WWW User Survey, Nielsen Media Research, Forrester Research etc.
