Phil in his “Now even Toyota” comment identifies the need for more lean managers and giving the customers what they want.
To add further comment - the basic problem currently is that companies are not selling what they were. If the obstacle is price then more lean managers (taking waste out and reducing costs) is the answer since prices can be reduced whilst margins are protected.
But if the obstacle is not price then the answer lies elsewhere.
To often companies solely concentrate on reducing costs whilst a similar focus on increasing sales would reap greater returns. They should start by asking the question “what products, services or resources have we got that can satisfy a need in the market places?”
