"Software by Numbers" by Mark Denne, Jane Cleland-Huang
From the Back Cover
IFM is a perfect fit for ExtremeProgramming. Where XP addresses levels 1-3 on the LevelsOfSoftwareSuccess scale, Software by Numbers addresses levels 4-6. XP's simple approach to architectural dependencies (EvolutionaryArchitecture) looks like it'll make IFM even easier to implement.
Although some people may be turned off by the numbers-centric view, I loved the focus on DeliverValue and putting costs into context. I think this book offers guidance for OnSiteCustomers that XP lacks. Highly recommended. -- JimShore
