I never do exercises when reading either, but I did this time. Great post!

As I worked through the exercises, I started thinking about how much each option is worth. Interestingly, it seems that the value of the options depends on the volatility of the price, not the absolute price. Does that imply that the less certain we are about the future of our software, the more we should invest in design?

This is the most user-friendly explanation on options I've seen.

I like this one a lot! And that includes the (not so) subtle kick up the backside about doing the exercises 😉

Nice! And yet another display of the effectiveness of your writing style, based on small morsels of text, hand drawn pictures, humor and acknowledgement of the reader's frame of reference.

Interesting analysis. I don’t think of it in those terms but I will now.

I love the connection between economics and the technical knowledge needed in order to put the theory into practice. You start with the concept, and finish talking about decoupling in a natural flow. Great post!
