At IBM and Hewlett-Packard, Allen's students were typically systems engineers and project managers, not computer scientists.

Formal methods

He encouraged them to improve upon the informal approaches to computer performance analysis that were (and still are) in common use, applying more formal methods and using mathematical models to predict how the performance of a computer system would behave as workloads increased.
