ABSTRACT
The project used for the case study is the garage project. The data preparation details varied between the programs used, but the information split logically into the two groups, namely control data and activity data. All good network scheduling programs contain comprehensive error detection routines, designed to recognize particular types of mistakes and report them to the planner for correction. Errors might result from transpositions or other reading errors, keyboard mistakes, omitted data, entering non-valid control data, or some basic flaw in the network diagram logic itself. Error reports will be generated, for example, if the planner has tried to enter a target project completion date which precedes the specified project start date. Network plots are useful both as management control tools and for checking that the correct logic exists in the computer model. Most software will allow materials costs to be entered as a total material cost for each activity.
