Working software is delivered much more quickly and successive iterations can be delivered frequently, at a consistent pace.The Manifesto for Agile software development, written in 2001, shows the emphasis that Agile places on value. Feedback can then be incorporated into the next or future iterations.Īgile evolved out of a number of different lightweight software philosophies which developed in the 1990s in counterpoint to heavyweight methodologies like waterfall. The goal of each iteration is to produce a working product, which can be demonstrated to stakeholders. The emphasis is on efficient face-to-face communication and short feedback loops. These teams are self-organising, include a representative of the business (the product owner). The work is organised in to a backlog that is prioritised in to exact priority order based on business (or user) value. Instead of extensive planning and design up front, Agile methodologies allow for changing requirements over time by using cross-functional teams – incorporating planners, designers, developers and testers – which work on successive iterations of the product over fixed time periods (timeboxes). The process doesn’t have its own momentumĪn Agile software development methodology – such as Scrum – is one which eschews a linear, sequential approach in favour of an incremental, iterative one.like those resulting from new technologies, changes in a market or changes to business goals) can’t easily be incorporated with the waterfall method and there are often laborious change control procedures to go through when this happens Solution designers often aren’t able to foresee problems that will arise out of the implementation of their designs.This way of working doesn’t handle this well. Often the people we’re building software for (the client) don’t know exactly what they need up front and don’t know what’s possible with the technology available.Often teams feel more comfortable with this approach. Because the waterfall process is a linear one it is perhaps easier to understand, especially for non-developers or those new to software development.The development process tends to be better documented since this methodology places greater emphasis on documentation like requirements and design docs.

If appropriate meaning an alternate solution is selected before any code is written. Potential issues that would have been found during development can be researched and bottomed out during the design phase.

They also then have a series of processes for managing work packages, exceptions, reporting, risks and issues. In general these methodologies have stages that deal with what you need to do before a project, during a start up phase, a planning phase, an execution phase and a closing phase. These include PRINCE2 which was created by the UK government and remains popular in the UK public sector and PMI PMP which is more internationally recognised. There are several well known and widely implemented waterfall methodologies that are used on IT projects. In waterfall methodologies all the requirements gathering and design work is done before any coding takes place. Royce is commonly credited with the first formal description in an article from 1970 in which he described a flawed software development model.) The waterfall was only codified when people subsequently realised that it wasn’t the only way of doing things. Rather it was inherited by enterprise software developers from other industries where, once a particular phase of production is complete (like laying the foundations of a building for example), it was incredibly costly or impractical to go back and make changes. The waterfall model is one in which each phase of a product’s life cycle takes place in sequence, so that progress flows steadily downwards through these phases like a waterfall. But what’s the difference between the two – and is Agile always better? Traditional waterfall methods for developing software are rapidly declining in popularity as more recently developed Agile methodologies are increasingly adopted.
