multiple tasks at the same time What if I’m working on two things at once? Not all tasks are best executed in isolation. Sometimes two tasks are related, and, because there is so much overlap, it’s actually more work to tackle one, and then the other separately. In these cases the most productive thing to do is work on those tasks at the same time... Sometimes working on both tasks at the same time IS the best option When you have two tasks that are closely related. then it’s not really a problem to work on them both at the same time. This is especially the case where the work completed in one task could inform decisions made in the work for another task. Rather than completing one task and starting the next, and then realizing that you need to do some work on the first task again, it is far more efficient to work both tasks at the same time. 120 Chapter 4 Task 3 MDE Create the schema for storing dates in a database Task 4 MDE Create SQL queries for adding, finding and updating date records 2 2 Download at WoweBook.Com � � Both these tasks involve writing database scripts, so in this case it might make more sense for Mark to be allocated both of these tasks at the same time. Rules of Thumb Try to double-up tasks that are related to each other, or at least focus on roughly the same area of your software. The less thought involved in moving from one task to another, the faster that switch will be. Try not to double-up on tasks that have large estimates. It’s not only difficult to stay focused on a long task, but you will be more confident estimating the work involved the shorter the task is.
