How, then, shall teams communicate with one another? In as many ways as possible. • Informally. Good telephone service and a clear definition of intergroup dependencies will encourage the hundreds of calls upon which common interpretation of written documents depends. • Meetings. Regular project meetings, with one team after another giving technical briefings, are invaluable. Hundreds of minor misunderstandings get smoked out this way. • Workbook. A formal project workbook must be started at the beginning. This deserves a section by itself.
