“you may ignore economics, but economics won’t ignore you” — Don Reinertsen “The measure of execution in product development is our ability to constantly align our plans to whatever is, at the moment, the best economic choice.” — Don Reinertsen

decision theory The analysis of complex decisions with significant uncertainty can be confusing because 1) the consequence that will result from selecting any specified decision alternative cannot be predicted with certainty, 2) there are often a large number of different factors that must be taken into account when making the decision, 3) it may be useful to consider the possibility of reducing the uncertainty in the decision by collecting additional information, and 4) a decision maker's attitude toward risk taking can impact the relative desirability of different alternatives.

decision tree

value of information • information reduces uncertainty about decisions that have economic consequences • information affects the behavior of others, which has economic consequences • information sometimes has its own market value Douglas Hubbard, How to Measure Anything (3rd edn), p145

measurement A quantitively expressed reduction of uncertainty based on one or more observations Douglas Hubbard, How to Measure Anything (3rd ed.), p31

perfect information Value of perfect information = EV after - EV before = $100k

not normally binary decisions — a continuum humans are risk averse when the stakes are high use utility functions; reduce stakes don’t capture time dependence use calculus monte carlo analysis problems with decision trees

opportunity cost In microeconomic theory, the opportunity cost of a choice is the value of the best alternative foregone, where a choice needs to be made between several mutually exclusive alternatives given limited resources. Assuming the best choice is made, it is the "cost" incurred by not enjoying the benefit that would be had by taking the second best choice available. Wikipedia

cost of delay Task A: upgrade package to support credit card encryption CoD: fine of $50,000 per day we’re not in compliance. Duration: 2 weeks Task B: Complete a feature for a key customer CoD: we’ll close $100,000 per week with this feature Duration: 1 week

cost of delay Task A: 2 weeks, CoD $250k / week Task B: 1 week, CoD $100k / week

urgency profiles

exercise Should I wait for the feature? We have completed sufficient features for 85% of our target customers. We can: a) Launch what we have, add last 15% in next release, 6 months from now b) Take 2 more months to finish last 15% Cost of delay for project: $200,000 / month
