SDLC, Process, and Methodologies

The main benefit of today’s Agile development methodologies such as Scrum or XP is the promise of delivering more in a shorter period of time and the value derived from having the flexibility to adjust your course mid-way through a development effort. But does this type of approach allow for requirements management? Is RM necessary given the shorte...

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 ...

Information System Development (or even the broader Information Technology field) is a relatively new discipline compare to matured disciplines like mathematics, physics or philosophy. It is difficult to find an agreed-upon definition on even a widely used term such as JAD. It can mean different things to different people, and it’s constantly evolv...

This article proposes innovative ways to combine three of the most important methodologies that have emerged in the past decade in the field of information systems architecture: UML, RUP, and the Zachman Framework. Over the past decade, the advantages of using the Unified Modeling Language (UML) for modeling software applications have become clea...
