Impact Mapping: Making a big impact with software products and projects

Mapping step 2: Find alternatives

Is it realistic that the feature will contribute to the impact? Is the impact valid for the actor? Will the impact really contribute to achieve the goal?

Mapping step 1: Draw the map skeleton

Preparation step 3: Plan your first milestone

Experiment with names

Challenge everything, in particular targets and constraints. Make sure that the targets are realistic and deliverable within the allocated time frame.

what we'll measure (Gilb calls it ‘scale’) how we'll measure it (‘meter’) what the situation is like now (‘benchmark’) the minimum acceptable value, the break-even point for investment (‘constraint’) the desired value (‘target’)

Tom Gilb has good advice on how to establish precise measurements for goals in his book Competitive Engineering.

Preparation step 2: Define good measurements
