The backlog of work in Accounts department gets bigger by the day. There are many staffing issues (numbers, training etc.) causing this. The upshot is that most of your junior colleagues are now regularly missing each week's target deadline. As the team leader, you must prioritise resolving this situation before it turns into an even bigger crisis.
What would be the most effective reaction to this situation?
Remind your team of the problems and the clear need to meet every deadline.
Communicate to your team that you are resolving the problems personally.
Stay positive - and ask your immediate superior for additional resources.
Meet with the team to tell them what you believe is causing the problems.
Correct answer is C
The MOST effective option is (C). This is because missing deadlines is a major problem which needs to be escalated to your manager. You need to know where they stand on this issue.
(A) is in fact the LEAST effective option since it only pays lip service - without taking any direct actions to address the growing problem.
Answer option (B) is slightly better than the LEAST effective option (A). You are indeed resolving the issue personally and reminding the team that this leadership responsibility falls within your managerial responsibilities.
Answer option (D) starts with the good idea of holding a team meeting. The aim here needs to be keeping the team on board and asking for their thoughts/opinions on what's causing the issues. Telling them can easily be misinterpreted as blaming them. In which case they will be less likely to help you with the problem resolution.
