Phillips takes this one step further and describes a project where the developer and tester roles are subsumed under the title of software engineer.

Other agile practices can also help challenge these negative prejudices; many of the case studies describe an approach termed pair testing (Sewell, 5; and Kingston, 15; for example). In this practice, developers and testers are paired (in a manner analogous to pair programming) to work together on software quality aspects of the development. This approach appears to have been particularly bene cial; in one such scheme, Thomas ( 6) reports that developers even began to actively seek out testers to bounce development ideas off them and to get their feedback.

. 24.4 Agile Requirements Management Without requirements h QR-Code for .NET ow do you know what it is you need to develop and how do you prove the software does what it is supposed to do These question are as relevant to agile projects as they are to traditional projects, except that the requirements elicitation process on traditional projects is often a long, complex, and notoriously dif cult task to achieve; it is estimated that as many as 75% of all projects fail because of issues with requirements [98]. The time taken to elicit requirements combined with the copious amounts of documentation that commonly need to be created and maintained seem completely at odds with the goals of agile development.

This section discusses a number of best practices employed in the case studies that enable requirements to be managed in an agile manner.. The Role of Use Cases and User Stories in Test Case Design A large number of the case studies (Sewell, 5; Wilson, 14; Kingston, 15; and Warden, 16; for example) report the bene ts of use cases [8] and user stories [20] in eliciting the customer requirements for the system. These approaches elicit simple and easily understood examples of how the user interacts with the system that is to be developed (or that is in the process of being developed) to produce some outcome of value to the customer. From a quality management perspective, the scenarios documented using these practices are not only useful in assisting the developers understand what they need to produce but also map very naturally into test cases.

Sewell, for example, describes how involving the testers in the requirements analysis alongside the analyst and customer representative enabled accurate and effective tests to be designed in parallel with use case capture, driving testing earlier into the project life cycle and ensuring that the customer was satis ed with the correctness of the resulting test case. Reducing Requirements Documentation Overload Keeping documentation and the need for document maintenance to the minimum level possible is a well-established agile principle, and a number of the case studies. Agile Testing: How to Succeed in an Extreme Testing Environment (Sewell, 5; and Evans , 19; for example) describe speci c practices that they have employed to achieve this. A great deal of documentation on projects is used for communication, such as passing requirements information to developers, testers, and other stakeholders. Sewell describes the value of daily stand-up meetings in improving communications and reducing documentation to manageable levels on a large agile project; the overhead of documentation is avoided because the team members are able to talk to each other about important issues, rather than having to type the information into an email or a change request tool, and can ensure that it is distributed to the people who need to know about it.

Sewell also describes the bene ts of having all the stakeholders co-located from the start of the project, and in particular the bene t of having testers work alongside the analyst and customer representative during the requirements elicitation task. In effect, this short-circuits the need to provide long, complex, and potentially out-ofdate requirements information to the test team. Evans ( 19) describes a number of techniques for improving communications that can provide direct, honest, speedy, and productive information exchange with the goal of producing fewer and less formal documents (such as the Weaver Triangle [72]).

The techniques that Evans describes can also be usefully applied to the process of requirements elicitation itself. Denning ( 8) makes an important point about the role of formal documentation in commercial projects, where it proved essential for a company contracted to perform a large and complex testing task on a commercially critical system to document the roles, responsibilities, and terms of reference for the project. Without this documentation, issues about the scope of the project and the responsibilities of the staff performing the work could have potentially put the pro tability of the contract at risk.

From a review of the case studies and the very different perspectives on the role and use of documentation that they provide, a useful approach is to not be dogmatic about documentation but to look for strategies to reduce the project documentation capture and maintenance load. Automation, such as requirements management tools, for example, could provide such a solution..

Look Beyond Requiremen QR Code ISO/IEC18004 for .NET ts to Real Customer Needs Gilb ( 4) makes the case in his Evo method [32] for delivering customer value rather than sticking slavishly to traditional requirements elicitation practices. A key principle of Evo states that you cannot know all the customer requirements in advance, but that you discover them more quickly during the process of delivering valuable working software.

Ensure All Requirements Have Tests Except on the most trivial of projects, without requirements how do you prove the software does what it is supposed to do Good testing practice demands that it.
