The planning phase setting project objectives,”in the planning phase broad goals of the entire project are set. In particular it most be determined if the system or only part of the system needs to be replaced. Whilst this does not seem to be significant step, it if very important to the overall project. It is through the setting of these broad system goals that the measurments of success can be determined. That is at the completion of the planning phase, a clear picture of what the problem is has been established and equally important, a clear pictyre of what outcome will resolve the process has also been established. It should be noted here that we have not identified what needs to built into the computer based information system there is a very good reason for this- at this stage it is not relevant. In the problem solving phase, the focus is on identifying the problem and what would solve not how the problem has arisen and how it should be so,ved. The solution is linked through the problem and trhough this a process for solving it developes. A computer based information system should never be created for the sake of creating it-it should be created to solve the problem that was identified. too often a computer based information system will be created but will not solve the problem that it was intended to solve. This can ussually be traced back to the initial planning phase. When the outcomes to solve the problem were established, they would focus on what the system could be made to do

Users are normally categorised by their level of knowledge of the operation system Novice need quick start guides, troubleshooting tips and user manuals that expalin basic processes in detials. Intermediate need more detailed user manuals which assume some prior knowledge troubleshooting guides and simple technical guides. Expert Need manuals with explanation of complex or advanced features Expert support specialist ussually software or hardware technicians whose role is to maintain the system. specialist those users depend on the use of interior monitor system to do their work. They may include data entry operations, web devleopters and graphic designers. Adjunctive people for whom information technology assissts in them work is not essential.

Read morescheduling and expediating,”projects rarely follow the plan (lard) out. During the project the project manager should access each step. If there are delays they should identify alternate actions to bring the project back within the time constraits often this is done by putting more resouces, time or money into a particular activity. THis course of action should be thought carefully. Time and costs need to be traded off to get the project completed. After the critical path and the slack time in other activities have been identified
