SOFTWARE DEVELOPMENT = PROBLEM SOLVING
Successful problem solving requires
finding the right solution
to the right problem.
Russell Ackoff, 1974
We fail more often,
because we solve the wrong problem
than because we get the
wrong solution to the right problem.

SUMMARY
Every project has an expected outcome
• Hierarchical hypotheses of behaviour changes
• Often not made explicit/not aligned
Behaviour changes as guide posts for your project
• Smaller batches with measurable risks/potentials
• Strategic control for projects/portfolios
Impact Mapping is a visual method for making hypotheses
and solutions options explicit and aligning them
