This is the Overview. Here you'll get a nice summary of your client's work. You'll find the color coding found throughout the system. Red means late, Green means on time, Yellow means about to become late, or was done a little late. Orange means an item recently became late. Blue represents newly assigned items or recently inputted Metric data.
Note that the Overview is meant for easy viewing -- you can't actually complete items here.
What's New
