Suppose a manager at a small consulting rm is deciding who to promote.

Employees A and B currently both do some analysis and some project management.

Whoever gets the promotion will exclusively do project management, and the other

employee will exclusively analysis. Employee A can a project management

task in 30 minutes and an analysis task in 60 minutes. Employee B can a project

management task in 30 minutes and an analysis task in 90 minutes. If the manager is

interested in boosting overall productivity, who should they give the promotion to?
