Loss aversion Losses outweigh gains

I ’ ll toss a coin. Will you take this bet...?

Heads: I pay you R2000 Tails: You pay me R1000

Heads: I pay you R3000 Tails: You pay me R1000

It may be an old crock, but it ’ s my old crock. Endowment effect:

I my revenue stream We have a solid revenue stream. Why would we spend it on innovating an expensive new product which might fail?

But you must innovate to survive “ The longer-term effect of the capital markets ’ preference for remaining at the same knowledge stage is stagnation. At some point [...] the company will be outflanked by competitors taking more exploratory approaches. Earnings will stop growing and analysts will savage the company for its lack of innovation. [...] Freeing up time and capital to engage in new activities creates enduring competitive advantage. Roger Martin, Dean of Rotman Business School, Toronto

The IKEA effect We overvalue the things we make

If you ’ ve ever built self-assembly furniture you may have noticed that you valued it more. The “ IKEA ” effect.

Dan Ariely decided to test the IKEA effect. With origami frogs. They were hard to make and most people did a bad job. How much would people bid for their own frogs? And the frogs of others? And expert -made frogs?

So maybe that piece of software you worked on is not quite so perfect after all.

To deal with the IKEA effect, gather responses to prototypes

Usability testing gives you a blast of vivid reality Can people use it? Does it make people happy? What don ’ t they understand? And why?

Bonus item... Reframe: Assume you will fail “ Discovery-based planning suggests that managers assume that forecasts are wrong, rather than right, and that the strategy they have chosen to pursue may likewise be wrong.
