Abstract: To raise precision and dynamics of Activity and its Process(ProA)time estimation in product development process, the concept of equivalent was firstly introduced, and equivalent attributes of ProA input and output item were studied. Furthermore, the concept of growth curve was proposed. Growth curve of atomic ProA and synthetic relationship of growth curves were also discussed in detail. Then, time estimation method and estimation model of product development were established. Finally, the feasibility of the method and model was illustrated by application example.

Key words: product development, time estimation, equivalent, growth curve
