Human-centred design is based on a continuous dialogue between potential users
and the designers of the system. The best results are obtained when usability
and the user's perspective are fully acknowledged right from the beginning of
the design process. The starting point for human-centred design is in knowing
the future users and identifying the most important situations of use. This
makes it possible to ensure ease of use and usefulness of the product or
Reduced development costs: the overall development time and costs can be
reduced by avoiding over-design and reducing the number of late changes.
Reduced support costs: easy-to-use systems require less training, less user
support and less maintenance.
Reduced operating costs: systems better matched to the users' needs improve
productivity and the quality of user's actions and decisions.
Improved product quality: human-centred design helps bring more competitive,
high-quality products into markets which keep demanding more usable systems.
