You have conducted two group meetings on the subject of telephone answering devices. In each group there were seven prospective users of such devices, and in the two groups there were four users of telephone answering services. (These services use an operator to intercept calls and record messages.) When the client's new-product development manager heard the tapes and read the transcripts of the two meetings, the first reaction was, "I knew all along that the features I wanted to add to our existing model would be winners, and these people are just as enthusiastic. Let's not waste any more research effort on the question of which features are wanted." What do you say?
