ABSTRACT
A job develops gradually over the years as activities are put together and modified to fit better with other jobs and with changes in the environment. Inevitably many valuable job modifications depend on the involvement of managers. They have power to make things happen and they also have a broader view of implications in combination with other jobs. In designing new information systems and job content the opinions and needs of users should always be considered. Some people tolerate a disliked job simply as a necessary nuisance, while throwing themselves enthusiastically into other kinds of activity. The general point is that thoughts about a job are certainly based on its content, but perceptions are not completely fixed. Part of the change comes from individuals themselves, as they shift job activities slightly to suit their preferences. Sometimes it's because people in a group allocate tasks between themselves to suit their different strengths.
