Taschenbuch. Zustand: Neu. Neuware - Extreme Programming Refactored: The Case Against XP (featuring Songs of the Extremos) takes a satirical look at the increasingly-hyped extreme programming (XP) methodology. It explores some quite astonishing Extremo quotes that have typified the XP approach quotes such as, 'XPers are not afraid of oral documentation,' 'Schedule is the customer's problem,' 'Dependencies between requirements are more a matter of fear than reality' and 'Concentration is the enemy.'In between the chuckles, though, there is a serious analysis of XP's many flaws. The authors also examine C3, the first XP project, whose team (most of whom went on to get XP book deals shortly before C3's cancellation) described themselves as 'the best team on the face of the Earth.' (In a later chapter, the authors also note that one problem which can affect pair programmers is overconfidence-or is that 'eXcessive courage' ). The authors examine whether the problems that led to C3's 'inexplicable' cancellation could also afflict present-day XP projects.In the final chapter, Refactoring XP, Matt and Doug suggest some ways of achieving the agile goals of XP using some XP practices (used in moderation) combined with other, less risk-laden methods.…

Taschenbuch. Zustand: Neu. Neuware - APPLICATION DEVELOPMENT IS USUALLY faced with several critical factors: time to market, ever-increasing quality, and cost of development. Time to market is critical in that any project that an individual or company may have in mind is probably already in the works elsewhere. When that is the case, everything comes down to being the first to deliver . . . even if it falls short. A Gartner Research study showed that competing products offering similar features will take the most mar ket share if released sooner. The study further added that the product released first, even with fewer features, typically builds market share faster. The lesson of that study is that it is important to release a 1. 0 version of a new product concept as quickly as possible and then follow up with feature add-ons over time. Product consistency and quality are also critical to the success of products making their debut. Applications with modules that look differently can under mine the application user's confidence in the product. The lower their confidence in the application, the less they use the product and come to depend upon it. The same can be said at the code level. The more modules that are implemented con sistently, the easier different developers can step in to investigate and resolve problems. Cost of development is often measured by productivity, or how much code is created to accomplish specific application tasks.…
