Liddell has spent almost twenty years working with clients at the shop floor level uncovering the many myths that surround MRP based planning systems and his findings are staggering.

Liddell found that even today, most ERP vendors are selling and implementing planning modules that are based on technology that was developed in the early 1980’s. Because these systems are fundamentally a materials centric view of the world, they have little, if any, ability to deal with time constrained events. Liddell concludes that selling planning systems that can’t handle time is one of the greatest con games ever perpetuated on the unsuspecting minds of manufacturing management.

Liddell feels that the damage to manufacturers who use these systems is far worse than anyone can ever imagine. Its not just the cost of adding buffers at every level and the constant confusion its also the dichotomy between planning systems that are constantly trying to increase waste and techniques such as LEAN that are attempting to eliminate waste.

The Little Blue Book on Scheduling tries to simplify these issues so that managers and executives can understand what they are really dealing with. Hopefully this information will not only stop them from making important decisions based on faulty information it will also lets them know what steps they should be taking to fix these problems.
