Thats collaboration
Using Google Docs, especially spreadsheets for time- and project tracking. Also for some kind of regular reports. Big advantage in comparison to XLS e.g is, that teammembers can enter and change data everytime collaboratively without sharing a document via mail nor having troubles with inconsistent data. Were using validations and all exports work well ,-)
