This project involves developing methods for managing design projects. The work sits at the junction of project management (PM) and new product development (NPD). The conventional project management methods accommodate only one form of uncertainty: stochastic uncertainty in task duration, for which PERT is used. There is room to think of radically different ways of conceptualising project uncertainty, and the management thereof, in engineering design, research and development. This project seeks to enhance the management of new product development by developing novel conceptualisations of how to cope with the uncertainties, and implement these as project management tools.
