What are you're 3 Top Priorities at work? I mean what 3 things are most important to you and your organization? If you don't have a good and fast answer for this question you probably should do some work in that area. From a business point of view it is dangerous to not have an answer because if you don't know what your top 3 priorities are then how do you and your team spend your day at work? If you want to increase your teams and/or your own efficiency, engagement and focus you have to know what your 3 most critical business challenges are. Write it down and review it with your Key Stakeholders and the Team. Get agreement that these are the most important tasks to work on. Without agreement it will be challenging to get the necessary commitment from the Team to really own the tasks. These Key Tasks should be communicated regularly to everyone. Be transparent, show what you and your team are working on, review it regularly in your Project or Staff meetings.
Why 3 priorities? In general 3 priorities is a good guidance based on my experience because most people can remember up to 3 objectives. If you use more you're running the risk of diluting your objectives. Don't try to be everything to everyone.
