Management have ultimate responsibility for your team - staffing, training, resources, workload and everything else. If one of those is wrong, it's their fault.

Management have ultimate responsibility for your team - staffing, training, resources, workload and everything else. If one of those is wrong, it's their fault. The alternative is pure scapegoating. Blaming a team or an individual doesn't get to the root cause - why did that employee underperform, why was that team badly led, why did nobody identify or report these problems until it was too late? The answer might be as simple as "we hired a complete moron", but management have to take ownership of that error if they want to prevent similar errors in future.
