Managing Team - Best Practice

Hey All,

I'm a project manager for a team in a creative agency. The staff is spread out across the country. I'm trying to figure out the best way to manage projects for the team and be able to report to our clients. Should each team member have their own sheet to manage their participation in our projects, or should we have a single project sheet for each project with each persons assigned tasks included? If we go the first way, then the same projects are mentioned in multiple people's sheets and are difficult to track. However, each person feels more empowered to manage their own sheets. If we go the second way, with overall project sheets, then having weekly accountability meetings with my team is difficult as I may not know all the projects they're involved in without having to flip through each overall project sheet to look for their names on tasks. I know there is some type of reporting feature, but not sure how that works. 

Any advice would be appreciated!
