A manager cannot ever blame a product delay on individual developers in a team. That's the whole damn point of being a manager and getting the top brass, large office and colored parachute: you must take responsibility for the end result, the buck stops at you. If a critical path activity is not completed and delays the product, it may be that an individual developer failed in his task, but it your fault as a manager for the product delay: you should have dedicated more time or more experienced talent to that component, you should have tracked it closely and corrected the problem, you should have communicated to upper management the objective reasons outside your control and team for a delay, etc. Otherwise, what does a manager exactly do? Sits around at his desk waiting for task to be completed on time like some sort of plantation owner?
