"Either [the designer] struggles to reduce the system to comprehensibility and wins, or else he loses control of it." - Conway #readingToday  

It is a natural temptation of the initial designer -- the one whose preliminary design concepts influence the organization of the design effort -- to delegate tasks when the apparent complexity of the system approaches his limits of comprehension. This is the turning point in the course of the design. Either he struggles to reduce the system to comprehensibility and wins, or else he loses control of it. The outcome is almost predictable if there is schedule pressure and a budget to be managed.
