This paper explores the performance of coupled development tasks subject to a deadline constraint
by proposing a performance generation model (PGM). The goal of the PGM is to develop insights
about optimal strategies (i.e. sequential, concurrent, or overlapped) to manage coupled design tasks
that share fixed amount of engineering resources subject to performance and deadline constraints.
Model analysis characterizes the solution space for the coupled development problem. The solution
space is used to explore the generation of product performance and the associated dynamic forces
affecting concurrent development practices. We use these forces to explain conditions under which
concurrency is a desirable strategy
