For agile methodologies to succeed, there needs to be maximum transparency and planning. A number of agile artefacts have been developed to ensure that the team and the stakeholders have a clear understanding of what's happening. Burndown chart For each sprint, the development team commits to developing the features described in a number of user stories . Each story is assigned a number of points during the estimation meeting . In order to ensure that all the promised features are developed during the sprint, the scrum master keeps a burndown chart to measure the team's velocity. On day one, the total number of story points is marked on the top left of the chart. The next data point represents the remaining story points after the stories completed on day one have been subtracted. The ideal trajectory is a straight line. If the team slows down (indicated by the "actual tasks remaining" line being above the "ideal tasks remaining" line) then they need to spee...
Usability testing is a useful tool in the developer's toolbox, but needs to be done consistently and fairly in order to make sure that everyone's expectations are met.

In this article on User Experience Prototyping , Paul Boag, who has been in the field of user experience for over a decade, writes about the benefits of prototyping. When most people think of prototyping they are thinking about mocking up a user interface. There is no doubt that prototyping can help in this area. Organisations use prototyping to define and test experiences using all kinds of interfaces. Interfaces from mobile apps to enterprise systems. He identifies three key benefits of prototypes: they are inspiring , and allow people to understand what is being proposed, because they show stakeholders what it will look like; they ensure a common vision - it is much easier to agree to something and come away with a shared understanding of it if you have actually seen what it will look like; they are testable - you can actually do usability testing with them and fix any usability issues b...
