Imagine you are head of human resources at Casual Contracting Co. Every month you hire a lot of temporary staff who spend 1-4 months with CCC before leaving. Sometimes you hire the same people again. Of late, you have noticed a strange process gap. You are paying same person two (or more) salaries.
This is because you are hiring a person for new temp role even before their current one ended. See above picture.
So how to avoid making such hiring boo-boos.
Simple, using Excel of course.Continue »

Outside of a dog, a book is a man’s best friend. Inside of a dog it’s too dark to read. -Groucho Marx
We don’t have a dog (yet), but we have a lot of books. Anytime I am in a bookshop, I feel like a mosquito in fat-camp. So you can imagine me smacking my lips when I saw your suggestions for favorite Excel books recently. There were more than 50 different books recommended by our readers. Of course I cannot buy all the 50 in one go. That would make Jo (my wife) angry. So I bought one that most of you recommended.
It is a book about array formulas, advanced formulas and data analysis techniques. I am eagerly waiting for the delivery to devour it. Once I am done with it, I will post a review here.
What about you? What Excel book are you reading now? Please share in comments.Continue »

Peppe added priorities to this. With his new version, progress is measured based on how much priority we assigned that particular task. Pretty neat eh?!?Continue »
