Good user interface design can be very crucial to the acceptability or otherwise of a software product. It can spell the difference between acceptance of a software product and its failure in the marketplace. If the end−users find the software to be too cumbersome or difficult to understand, then an otherwise excellent product could be doomed to failure. While the developer looks to make the software as professional as possible, he/she should also as much as possible and as matter of importance consider user friendliness.
Unfortunately, it has been observed that many companies pay little attention to the mechanics of good user interface style. "As long as it works, that's what matters!" seems to be their mantra, with little regard for the inconvenience that this imposes on the user.
Some important factors to be considered in design of good user interface include
- Ease of use: A software product that always force the user to consult manuals cannot be considered as user friendly.
- Flexibility: A software should allow users to perform tasks quickly and efficiently without sacrificing power and flexibility
- Aestheticism: Aestheticism simply put means pleasing appearance, an interface should be that to which the user is attracted.
Design considerations such as the use of buttons and list boxes for data entry, instead of typing it in by hand, pop−up dialog boxes, to guide the user along the way, use icons and other graphics can go a long way in achieving user satisfaction.
A system designer must strive for excellence by paying close attention to the elements of software usability and flexibility. These are critical elements of software excellence, and they are worth pursuing.
