Extract

Occasionally, in the midst of satisfying customer requirements, we have to assess whether or not we are really making progress in terms of achieving more effective helicopters. We should identify both the areas which offer the greatest potential for improvement and those in which improvement is the most required. Then, we must decide on the amount of effort we will put into improving these areas.
