21. A Software Development Processs scales if (and only if) the effort it takes to manage a project increases at a slower pace than the amount of work being managed!
22. Relative Effort needed to manage a project when the project size increases Effort to Manage Does not Scale Neutral Scales Work being managed
24. Experiment Count “things” to manage Assess effort needed to manage those “things” If work to manage them increases faster than the number of things => process does not exhibit the property of Scalability
25. Growth in effort to manage those “things” Growth in number of “things” >
39. N Requirements organization in Agile 1 Portfolio Items – Customer marketable Epics Longer term planning (more than 1 iteration) 10 Features Where the rubber meets the road – what we do in one iteration User Stories 100
40. Different content abstractions for different stakeholders Product Marketing and Portfolio Portfolio Items – Customer marketable Epics Longer term planning (more than 1 iteration) Product Owner + Architect + UX Features Where the rubber meets the road – what we do in one iteration User Stories Team + Product Owner

42. As a Project Manager I want … 1 Epics 10 Features Less stuff to manage, so that I can keep my sanity!
43. Effort to manage N requirements with an Agile Requirements model Nx/102 Where N = number of requirements/user stories
44. The mental sanity graph…(BTW: lower = better) Waterfall Effort to Manage This is the difference between Agile and Waterfall The bigger the project gets… Where you want to be: Work being managed
