  8. 8. Feature Injection<br />Feature Injection helps us incrementally and Iteratively:<br />Discover the real business value<br />Explore the problem domain<br />Explore the roles, incentives and required product capabilities<br />Evolve’s everyone’s understanding of the problem as the solution also evolves<br />

  13. 13. “Users ultimately dictate solutions to us, as a delta from the previous set of solutions we’ve delivered them. That’s just human psychology <br /> – writer’s block when looking at a blank page, as compared to the ease with which we provide ‘constructive criticism’ on somebody else’s work.” – Udi Dahan<br />

  21. 21. Aim to understand…<br />That which helps achieve the business value:<br />Who will use the product? (roles)<br />What do we need them to do? (behaviours) <br />Why would they want to do it? (incentives)<br />How are user behaviours exhibited? (examples)<br />As these things solidify, we can pull “business value increments”<br />into a structure that makes it easy <br />to incrementally deliver these in our product<br />
  22. 22. What-if<br />Example<br />Discussing the resulting evolution to the model may<br /> then inspire more examples<br />Reflect – in scope?<br />Evolving<br />Model<br />Elaborated Example<br />(Test)<br />Feature<br />Group of cohesive examples<br />
  23. 23. Exploring the solutions<br />Business Value<br />Feature<br />Feature<br />
  24. 24. We now have an understanding of…<br />Value: What is our motivation?<br />Roles: Who will use our product?<br />Behaviour: What do we need them to do?<br />Incentives: Why would they want to do it?<br />Examples: How are user behaviours exhibited?<br />
  25. 25. <some business value sought><br /><some solution increment><br /><some role><br /><some product capability><br /><some benefit to the role><br /><some solution increment><br /><some role><br /><some product capability><br /><some benefit to the role><br />
  26. 26. User Stories <br />Grouping of cohesive examples<br />Explains the role, capability and incentive<br />As <some role><br />I want <some capability><br />So that <some benefit to the role><br />XP Day 2001 session “Tuning XP” - Rachel Davies and Tim McKinnon<br />
  27. 27. <Value sought><br />As <some role><br />I want <some capability><br />So that <some benefit to the role><br />As <some role><br />I want <some capability><br />So that <some benefit to the role><br />Should <achieve some<br /> outcome for<br />some stimulae><br />Should <achieve some<br /> outcome for<br />some stimulae><br />Should <achieve some<br /> outcome for<br />some stimulae><br />Should <achieve some<br /> outcome for<br />some stimulae><br />Examples<br />
  28. 28. Example<br />PrintCo – a Printer Manufacturer<br />We need mandatory registration on our website<br />
  29. 29. Why? Because we need more e-mail addresses<br />Why? Because we want to e-mail more customers<br />Why? Because 3% of them buy consumables and this will increase our consumable sales figures<br />So ,we will increase revenue by increasing our mailing list<br />
  30. 30. Role: PrintCo Customers<br />Behaviour: Give us their e-mail addresses<br />Incentive: Get special deals on consumables<br />Printer Driver & Management Software Update?<br />Reminder e-mail page?<br />

  32. 32. Increase PrintCo Consumable Sales<br />As PrintCo Customer<br />I want to be asked for my e-mail address via the website<br />So that I can get monthly e-mails with special deals on consumables<br />As a PrintCo Customer<br />I want to be e-mailed with deals specific to my printer<br />So that I don’t have to wade<br /> through irrelevant info<br />Should capture valid email address:<br />name[+comment]@somwhere.com<br />Should reject <br />black-hole addresses: *@example.com<br />Should contain <br />Single ownership consumable deals<br />Should contain multiple ownership consumable deals<br />Examples<br />
