Having a leadership team that speaks and acts in one voice is a key component of a strong corporate culture. Japanese car maker Nissan took this management lesson to a new high this week. It had organised a multi-city launch for its new entry segment vehicle rediGO (under the Datsun brand). While the launch was backed by a huge amount of publicity, its public relations team overlooked a simple fact: two press releases that went out from two different city offices - Chennai and New Delhi - used the same statement to describe the car, but attributed it to two different spokespersons from the company. The Chennai event was held on Monday; the Delhi launch took place on Tuesday.
