I’m currently reading ‘Critical Chain‘ by Eli Goldratt, which is a book on project management disguised as a business novel. It is interesting enough to warrant its own blog post later, but I couldn’t keep myself from citing it on this particular subject right away. I’m an opponent of multitasking (although I don’t always manage to practice what I preach), and here’s another reason why (images adapted from the book):
Suppose you are working on three things A, B and C, and each takes 10 days (or hours, or minutes) to complete. Your lead time for each task is 10 days, right?
Now, what happens to the time you need to check these tasks off your to do list, if you interrupt each task when you’re half way through?
It doubles!
So here you go, another good reason to stay focused, demand prioritization and stop multitasking.
