The designer who voluntarily presents his client with a batch of layouts does so not out prolificacy, but out of uncertainty or fear. He thus encourages the client to assume the role of referee. In the event of genuine need, however, the skillful designer is able to produce a reasonable number of good ideas. But quantity by demand is quite different than quantity by choice. Design is a time-consuming occupation. Whatever his working habits, the designer fills many a wastebasket in order to produce one good idea.
