Since conceptual integrity is the most important attribute of a great design, and since that comes from one or a few minds working uno animo, the wise manager boldly entrusts each design task to a gifted chief designer.7 Entrusting has many implications. First, the manager himself must not second-guess the design. This is a real temptation, because the manager is quite apt to be a designer, but one whose design gifts may not be as great as the best who report to him (design and management are very different jobs), and one whose attention is surely fragmented among other tasks.
