Read more [CONTINUED] Whereas the traditional "waterfall" approach has one discipline contribute to the project, then "throw it over the wall" to the next contributor, agile calls for collaborative cross-functional teams. Open communication, collaboration, adaptation, and trust amongst team members are at the heart of agile. Although the project lead or product owner typically prioritizes the work to be delivered, the team takes the lead on deciding how the work will get done, self-organizing around granular tasks and assignments.
They have specific features that make them better suited to different situations, but in general, the different agile software development methodologies adhere to the same basic principles: Individuals and interactions over processes and tools Working software over comprehensive documentation Customer collaboration over contract negotiation Responding to change over following a plan You can read about the different agile methods and how they compare in our whitepaper: Along with XP, it is perhaps the most well-known of the Agile methods, and also the most precisely defined which means that there is a lot of documentation and pre-built process for teams that are willing to adopt the methodology completely.
When used for software development, the aim is to control and manage the flow of features represented by Kanban cards so that the number of features entering the process matches those being completed.
More Information on Kanban Extreme Programming The idea developed by Kent Beck was to use best programming practices but take them to the extreme — hence the name.
As such, none of the individual concepts of XP are really new, but their application and combination is what makes XP different. RUP is process-heavy, and although the AUP is intended to conform to all the principles of the Agile Manifesto, it debatable how well it succeeds.
For example, Agile methods should support self-organizing teams with no management hierarchy, however it is hard to ignore the fact that the AUP has, to some degree, inherited the process-heavy nature of its parent, RUP. The counter-argument is that the AUP does not enforce any of the process guidelines it offers.
As with some other Agile methods, initial requirements elicitation are excluded as is any delivery process at the back end. The Agile Unified Process is more up-front loaded than most Agile methods, requiring a considerable amount of modeling before implementation begins, which in turn demands some degree of early requirements analysis.
While this is not a bad thing, care must be taken not to go too far and do waterfall-like detailed requirements analysis. Further, the proposed incremental development releases between production releases are not necessarily production quality and so again, the lifecycle can appear more waterfall than Agile.
However, this requires early development of the GUI which can produce wasteful discarded versions and de-emphasize underlying functionality.
Like most agile development methods, DSDM Atern puts quality and schedule first, leaving functionality as the lone variable. The method of prioritization used is called MoSCoW, offering four simple requirements categories: Alongside all the standard principles that define Agile processes such as stakeholder involvement, and build early and often, DSDM Atern also advocates a degree of formal tracking and reporting which is not so common amongst Agile methods.
DSDM Atern addresses the narrow scope of some other methods such as Scrum by including pre and post-development phases in its purview making it a true project management process as opposed to a focused development process. It is also a method with a detailed process description and therefore it can take some time to embrace DSDM Atern fully.
RUP was a framework from which elements could be used for each project as necessary, which was a good job really as over the years it grew to be humongous and it is highly improbable that any single project used it all.
As with its early forbears, DAD offers more than any single project would want and, in some cases, even proposes a number of alternative solutions from which to choose. Even if it is not adopted in full, DAD offers ideas that can be integrated into other project environments.
Feature-Driven Development FDD Feature-driven development FDD is an iterative and incremental software development process that follows the principles of the agile manifesto.
The idea is to develop the high-level features, scope and domain object model and then use that to plan, design, develop and test the specific requirements and tasks based on the overarching feature that they belong to. The idea is that developers generally write their tests after the code is written and therefore are only testing the functionality as they wrote it, as opposed to testing it to make sure it works the way it was actually intended!Applying project methodology in agile development.

Overview of Agile Methodology Essay - Chapter 3 Agile Methodology Overview Agile software development is a group of software development methods based on iterative and incremental development, where requirements and solutions evolve through collaboration between self-organizing, cross-functional teams.
