The first thing i do in the am when i open Wrike, is to 'start' and 'pause' the time tracker for each task/project that i will be working on, as well as my generic Task - Daily Activities.
Daily Activities includes, email checking, phone calls, interruptions that take 5 minutes of your time, etc. This has been given 25% for Allocation in the Workload section as these have been pretty much adding up to 2 hours a day.
So, let's say i am working on TASK 1 and the timer is going. Someone walks in my office and interrupts, i move my mouse up to the time tracker at the top of the Wrike app, choose the drop down, select Daily Activities, and track that. This way, the time i spend with this person does not go toward TASK 1.
Plus, with all my Today Tasks already listed in the time tracker at the top, it's easy to select the next task and get working on it. Helps me plan my day.
I hope this helps everyone!
