Faced with this situation, we must first determine the specific direction of the task arranged by the boss. Don't be afraid of the boss blaming you for not understanding his meaning. Ask boldly, so that you can know which departments need to cooperate with your work, and at the same time, you can work out some budgets and expected results of the project. When you set a goal, you must call a simple meeting of relevant departments in the name of the boss to determine all the things that need to be completed. Under the premise of a clear division of labor, there will be no promotion from other departments. At the same time, you must make a copy of the meeting and report it to the boss.
In the process of completing the task, you must always pay attention to the progress. When faced with some difficulties, try to solve them by yourself. But when you really can't solve it yourself, let the boss come out to preside over it as soon as possible.
When the task is completed, the efforts of team members must get positive feedback.
