There are only four basic kinds of work in organizations. There are activities, processes, projects, and systems. Activities are one-offs, or things that are done for which there is very little precedent and that will only be done one time. So for example, if auditors show up in your office and a superior asks for someone to get them lunch, one or more people will have to invent a good way to do the job. However they do it will never be written down, will never be repeated, and will soon be forgotten. This is a classic activity, in that its work method is spontaneous and invented. It is guided by few rules, 1 there will be no repetition, and there is no need to learn and improve.
