If the first 10 percent of design effort accounts for 90 percent of project success, how might that reality change the design effort?

Most owners, as well as designers, builders, and consultant teams, agree that such an approach embodies success in delivering a building that not only improves life-cycle costs but also offers a greater potential to reduced first costs.
