Today the term "user friendly," as applied to EDP systems, has become fashionable in many circles. Considering some of the bad press given computer systems in recent years (e.g.. "To err is human, but to really foul things up takes a computer"), the suggestion that systems can actually befriend their users is attractive.
Over the last decade a change has been occurring in users' expectations of the services that EDP systems should provide. Many users have come to believe that data processing should be more than a passive tool for the solution of predefined problems. They want systems to provide the kind of active support that encourages new ways of solving problems. This can't happen without a new, comfortable, even friendly. relationship between systems and their users.
What exactly is this elusive quality and how can one determine which systems have it and which do not? There is no precise definition of user friendly since the features that a system can offer its users vary widely depending on the system's environment - online or batch - and its application - technical, financial, administrative, etc. Nevertheless, experience suggests that user friendly systems typically share some or all of the following characteristics:
In addition to these features, user-friendly systems must provide good performance, be reliable, and be available when the user needs them. User-friendly systems should also be well documented. A clumsy system, however, cannot be improved simply by documenting all of its idiosyncrasies.
Maintainability is, of course, an important issue, but it is not specifically addressed in this context since it is really related to a separate systems attribute, namely, maintenance friendliness. Strictly speaking, the end user is not concerned about the ease or difficulty of the service technician's job.
There are other user-friendly features that could be added to this list, but if you are fortunate enough to be introduced to a system that meets most of these basic criteria, take a few minutes to get better acquainted with it. You may have just found a new friend.
