Therefore, you will need to write your User Manual for persons not as deeply involved in the system's development as your Client. Some products may indeed have broader markets and therefore may need more carefully constructed User Manuals, but the default assumption is that the Client and unknown colleagues of the Client will be the principal users of your product and the target readers of your documentation. Growing a Document Writing a user manual shares several properties and objectives with the writing of many other kinds of documents. A document should begin as an outline. Even if the outline lacks detail and will require changes later, the outline helps to organize ideas and format presentations.
Form is liberating.
The User Manual should be structured so that a sequential reader can understand the system in one pass through the document. Many students write documentation as if the whole truth must be revealed from the outset. They include excessive, extraneous detail from the first paragraph. This is not an effective writing strategy. Often it is most effective to sneak up on Truth.
