Time management:
Many times project managers who are overloaded seem to be constantly fighting one crisis after the other. It just doesn’t seem to stop. You need to quickly determine what to do when and how much time you have. You cannot micromanage every single task as a program manager, and you’ll have to start focusing on managing your time among all your projects.
Checklist for managing multiple projects: You should create a portfolio checklist for managing multiple projects. You could use a life-cycle checklist to help (e.g., Have I received all the specs? Have I involved QA on each project team?).

Prioritization of projects:
You need to determine which projects are more important than the others. When faced with multiple projects, it’s important to decide what to do and in which order it gets done. It’s no use simply selecting any project you like and paying attention to that project alone. Careful analysis is needed to ensure that each project meets your company’s strategic objectives and that you are aware of target dates.

Categorize your work:
This strategy reduces complexity. You have to make progress on all fronts when managing multiple projects. Don’t leave one until next week and expect results. Check the progress of each project on a daily basis.

Sequence work tasks:
Ensure that for every project the tasks have been properly sequenced and that they make sense. I have seen managers run from project to project, grabbing at straws. It’s imperative that each project be clearly broken down into manageable tasks and that they be correctly sequenced.
Create a dashboard: Use a digital dashboard to effectively capture and report on all the projects within your portfolio.
