ABSTRACT
This chapter begins by demonstrating simple bar charts, which can be adequate for planning and progressing small projects. They are particularly useful during the early phases of even very large projects, when there is little or no detailed information available about the tasks that lie ahead, so preventing precise planning. The chapter looks into an aircraft component project to see how much more effective would be for the L-F controls company to plan its work with critical path networks. It shows that bar charts are very limited in their ability to show the constraints between interdependent activities. The linked bar chart could not show all the links clearly, even for the simple project carried out by the L-F Controls Company. The predicted timescale for a project is too long, and that was the case in this example, with the client specifying that he wanted to fly in and house his airplane between days 50 and 55 of this project.
