TABLE OF CONTENTS It is easy to point fingers. Understand the causes before assessing blame.
There are as many nontechnical reasons for failure as there are technical ones.
The scheduling tool may be adequate, but the failure was caused by the way the project was executed.
If the tool is not used, the project is a failure.
Chapter 11 described five classes of APS success. Why does everyone not easily get these benefits? Why is it so hard to succeed with these tools?
There are thousands of scheduling systems in use with varying degrees of success. There are implementations that are everything that the factory ever dreamed of. There are other implementations that have not worked out so well. We suspect that many more thousands of implementations have been attempted and have failed. If you consider the number of vendors and the length of time scheduling systems have been marketed, there should be many more successful implementations many, many more. Compare the installed base of factory planning systems with the installed base of project planning tools. Is there a factory planning tool equivalent to Microsoft Project? There are hundreds of thousands of factories, but the number of factories using advanced planning tools is relatively small. In this chapter, we will discuss various reasons why scheduling systems fail and why they are so hard to install and use.
If the system is not being used or the implementation is not considered a total success,...
