Specification by Example was very inspiring book I red several years ago. Finally I get in the point to read another book from Gojko - Impact Mapping.

I am glad to say that this book is also very good. It is kind of "Cookbook" for me and I like the way it is written - very easy to understand and summarizing all important things.

I can definitely recommend this book and here are some citations which I noted down:

• Gerald Weinberg defined quality as ‘value delivered to some person'. 
• The role of testing becomes to prove that deliverables support desired actor behaviours, instead of comparing software features to technical expectations. If a deliverable does not support an impact, even if it works correctly from a technical perspective, it is a failure and should be treated as a problem, enhanced or removed. 
• A common cause for the disconnect between business and delivery is that teams iteratively deliver items that are too small to make a difference from a business perspective. Projects become endless streams of small items going through the pipeline, with no big picture or big benefits. 
• Iterative not incremental. 
• Good goals should be translatable to money, so we can decide what the appropriate return on investment is. 
• Not costs, but investments. 
• Goals need to be measured. 
• The ideal group to define the goals and draw the initial roadmap is a mix of technical experts and business decisionmakers. Without decision-makers the exercise is pretty much pointless, because they have to define the key objectives and approve alternative solutions. 
• Criticising too early can kill the discussion before people have come up with good alternatives.
