Agile Methods

Agile Modeling (AM) defines a collection of core and supplementary principles that when applied on a software development project set the stage for a collection of modeling practices. Some of the principles have been adopted from eXtreme Programming (XP) and are well documented in Extreme Programming Explained, which in turn adopted them from commo...

One of the unfortunate aspects of industry-level paradigm shifts, such as what we're seeing with the move to agile software development, is that the followers of the incumbent paradigm often get to set the tone of the conversation. A perfect example of this is that traditionalists will often claim that agile approaches are riskier than traditional ...

Extreme programming (XP) introduced the practice of expressing requirements in the form of user stories, short descriptions of functionality–told from the perspective of a user–that are valuable to either a user of the software or the customer of the software. The following are typical user stories for a job posting and search site: ...

We know that we must involve all the stakeholders if we want to discover a project’s requirements. But we need some guidelines on how to involve the right people and, given how busy everyone is, how to minimize the time and maximize the result. In this article, requirements expert Ellen Gottesdiener (www.ebgconsulting.com) shares her consider...

A fundamental reality of application development is that the user interface is the system to the users. What users want is for developers to build applications that meet their needs and that are easy to use. Too many developers think that they are artistic geniuses – they do not bother to follow user interface design standards or invest the e...

Just how important is it to fully develop your project’s requirements? After all, nailing down your requirements usually takes only 8% to 15% of your overall project effort. Truth be told, it’s not really something you’ll want to spend your resources and energy on—unless, that is, you care at all about the quality of your pr...

In the last few years, the agile software development movement has created a paradigm shift in how we work to understand system requirements. Agile teams shape software systems using a collaborative process, with executable software at its heart and documents marginalised to a peripheral role. This creates a fundamental shift away from tools for ma...

A few years ago I took a photograph an old wooden tombstone. The tombstone read, “Walter Crumbly, Hanged by Mistake – Sorry Walter.” It seems like the software industry wants to collectively hang the waterfall software development method and structured methods. In the not too distant future the software development industry will wake up and realize...
