Recent business environment development forces companies to speed up their new product development (NPD) cycle. The three-dimensional concurrent engineering (3DCE) offers chances to accelerate the process of new product development. However, to date there has been no formal guidelines for 3DCE NPD. This study tries to relate the imperative of concurrency into the stage-gate NPD, especially at the detailed design phase, in which the NPD team is presumed to conduct the decisions on product detailed specifications and production process design simultaneously. A mixed-integer non-linear programming (MINLP) mathematical model was developed to optimize operational manufacturing profit. The main features of the model are to select the best components from available alternative components, to take make-or-buy decision of the components, and to select its suppliers. In addition, the total quality of the components was evaluated and then compared to an expected total quality obtained from the competitors’ product or ideal expectation of the NPD team. A case from a leather bag company was used to demonstrate the model. In this case, sixteen components from 24 alternative components and seven suppliers for a new leather bag product case had to be decided and it was solved by the model. The sensitivity analysis provided evidence of model validity. Finally, a conclusion with several potential future works is provided
