Commercial packages usually do not create optimal schedules when resource leveling is necessary. The problem is that no single heuristic scheduler is consistently best, and optimizers sometimes take excessive time. Yet using a sub-optimal schedule is inconsistent with the new ethic of competing on time as espoused, for example, by Stalk |6|. The impact of unnecessarily slow projects on a business is often underestimated: particularly losses from getting to market later and subsequently losing market share. The more easily estimated lateness costs of over-budget labor and equipment, and late penalties are only some of the consequences. This suggests commercial software vendors should provide optimal scheduling as an option.

The author's solution to the problem of obtaining, optimal resource-levelled schedules is a FORTRAN . program that takes a commercial package's exported data, computes an optimal schedule using an optimizing algorithm, then provides the optimal schedule in a form that the commercial package can import—thus providing an optimal schedule within a commercial package.
