This paper outlines a framework for the analysis and evaluation of product development or improvement decisions based on product attributes and utilizing techniques such as Conjoint Analysis to provide data on customer preferences for product attributes, Activity Based Costing to cost product attributes and computer simulations to project results over time. The importance of speed and resource availability in project evaluation and the use of development projects to analyse, plan and control strategies is discussed. The paper also discusses how market simulations of the organizations own product and competing products through future time periods can be integrated with project plans, product attribute performance and attribute costs in a computer modelling system.
