Impact mapping and agile impact management is a high-impact collaborative and visual technique to
IMPACT MAPS: This is one of the most high-impact and simple methods I have come across in years to "bridge the goal-results gap" between business goals and delivering results that actually achieve those goals, and that "bridges the communication gap" between business people and R&D.
QUPER: During this workshop, I also introduce (and we apply) the QUPER model for requirements -- another great "tool" that I've found that is a simple, skillful, collaborative, and visual approach to discussing and quantitatively defining the "...ilities" of a product or feature. QUPER helps us identify and visualize the axes of cost, value and quality, and estimate cost-benefit breakpoints and barriers of quality and expose them for discussion. We combine the QUPER and impact map modeling together.
Evo, Planguage, Value Management: I also introduce (and we apply) concepts from Tom Gilb's refined Evo management approach combined with his Planguage and "Value Management" methods.
During this workshop, I first introduce the ideas and method, and then facilitate an actual impact-mapping workshop for the next release of your product/system.
This is best attended by business leaders (senior managers, product managers, department leaders, ...) who have business/product goals or organizational change goals. Plus, attended by R&D/engineering or operational people who will implement solutions to achieve them.
