Today, in new product development projects, “NPDs”, time is the cutting edge. The time to market in new product development projects is a key factor in the competition between innovative companies. Research has shown that time can be managed, and speed too. Our concern in this paper is to study the time factor in the case of new product development projects based on a time-cost trade-off curve, which is important for the project success by delivering the product as fast as possible. We will explain the motivation behind delivering fast in NPD projects. In construction projects, a customer initially contracts for a project from a contractor based on specifications, budget and delay. Time to market is a key success factor in new product development projects. Does time to delivery have high importance in construction projects? We conclude by showing the significance of NPD projects’ speed with respect to management in construction projects.
