Agile Modeling: Effective Practices for eXtreme Programming by Scott Ambler

By Scott Ambler

The 1st publication to hide Agile Modeling, a brand new modeling strategy created particularly for XP tasks severe Programming (XP) has created a buzz within the software program improvement community-much like layout styles did numerous years in the past. even though XP provides a strategy for speedier software program improvement, many builders locate that XP doesn't enable for modeling time, that's severe to make sure that a venture meets its proposed requisites. they've got additionally came upon that normal modeling strategies that use the Unified Modeling Language (UML) frequently don't paintings with this system. during this leading edge e-book, software program improvement columnist Scott Ambler offers Agile Modeling (AM)-a process that he created for modeling XP initiatives utilizing items of the UML and Rational's Unified method (RUP). Ambler in actual fact explains AM, and indicates readers tips on how to comprise AM, UML, and RUP into their improvement tasks with the aid of a number of case experiences built-in in the course of the book.AM was once created through the writer for modeling XP projects-an point missing within the unique XP designThe XP group and its author have embraced AM, which should still provide this ebook robust marketplace acceptanceCompanion website at good points updates, hyperlinks to XP and AM assets, and ongoing case reports approximately agile modeling.

Example text

To travel light requires courage, to trust that you’re not going to need a certain artifact but are prepared to create it if you are proved wrong in your assumption. Traveling light enables simplicity in your approach to development because your artifact maintenance efforts during development are dramatically decreased. Assume Simplicity As you develop, you should assume that the simplest solution is the best solution, and as the title suggests, this principle is clearly derived from AM’s value of Simplicity as well as the Agile Alliance’s principle of simplicity (2001b).

This takes courage. I believe that courage is a fundamental requisite of agile software development. First, courage is important because you need to choose to take an agile approach, and then stick with that approach when the going gets tough (and it always does). There will be people in your organization with other visions—you need to adopt the XYZ tool, you need to adopt a heavy-weight process, management needs to exert greater control, you need to outsource all of IT, you need to follow the dictates of this other department— and they will fight your efforts every step of the way.

He points out that you can’t always predict what you’ll need in the future and you’re just as likely to be wrong about it as you are to be right. Therefore, why develop, test, and maintain that extra functionality, functionality that you definitely do not need right now and may never need? Wouldn’t it be better to focus on fulfilling the current needs of your project stakeholders today, thereby keeping them happy (always a good thing), and instead have the courage to assume that you can solve tomorrow’s problems tomorrow?
