Until relatively recently, design was commonly perceived as a predominantly individual activity; the designer, trained in his or her (>) craft, was expected to identify, frame, and solve a design problem more or less in isolation from others. In the twenty-first century, however, this perception of the (>) design process is becoming increasingly removed from actual practice. Designers today routinely work in teams, collaborating to create processes and products that reflect the different kinds of expertise amongst the team members—and designers who are not skilled as collaborators are increasingly unlikely to be successful.
