By joining the two you really do get the best of both - as this study indicates. More short-term project goals, much more accurate work in progress limits, constant streamlining of the process and a good team-building stand-ups every day. If this seems like a good solution, why not try Kanban Tool?
It allows you to see a nice, graphic representation of the workflow, that will enable you to get an "at a glance" idea of the current status. It makes team collaboration easy and enjoyable (no matter how far apart the team members may be) and it provides extensive Analytics, which will be your base of finding what your team can improve upon. Together with Time Tracking, My Work widget and online attachments, this is the best place to take your first step towards a great productivity increase.
