Suppose, an investment advisor gives you the following two options to invest in:

Fund A: 7.8% with volatility of about ± 0.6% Fund B: 11.7% with volatility of about ± 8%

Two biased coins.

You can choose the coin, and the call. If you call correctly, you get 100,000 tax free, 0 otherwise.

You choose coin B, and call “heads” and it lands “tails” up.

How good was your decision to choose coin B?Clearly Wrong 1---2---3---4---5---6---7 Clearly Right

Coin A: p(heads) = .45 Coin B: p(heads) = .55

A small business has to choose between two technologies, A or B, to incorporate in the planned new product development and launch.

Based on all information, technology A has a 52% chance of success and B has 48%.

If they choose the correct technology platform, they will get net after tax profit of 7.5m for the year, and nothing if they fail.

They choose technology A, and the product fails, and a competitor chooses technology B, and their product succeeds.

How good was the decision to choose technology A?Clearly Wrong 1---2---3---4---5---6---7 Clearly Right

What Influences Decision Outcomes

Decision Outcome

Chance

Executing the Decision

Source: Russo and Schoemaker, Winning Decisions

Good outcomes do not imply good processes, nor do good processes guarantee good outcomes.

Good processes give the best odds of good outcomes.
