Too many user stories begin, "As a user …" Who is your user? Or, more accurately, who are they? Improving your understanding of the types of customers who use your software lets you see multiple products where previously, there was only one—and identifying dedicated products will help you prioritize and accelerate delivery.
Agile emphasizes just-in-time requirements rather than upfront preparation. The requirements person—be it the product owner, business analyst, product manager, or someone else—embodies the understanding of what is needed, and the user story represents the work that needs doing. This article details what user stories are (and what they are not).
Developing software correctly is a detail-oriented business. George Dinwiddie writes on how using the Three Amigos strategy can help you develop great user stories. Remember, the goal is to have the work done just in time for planning and development. It should be complete enough to avoid stoppages to build more understanding, but not so far in advance that the details get stale.
The needs to improve the time to market of a quality product and adapt to a changing business environment are driving organizations to adopt agile practices in order to be competitive in the marketplace. However, a project team is bound to face difficulties if it is not trained on the fundamentals of agile. Read on to learn how to design scenarios for agile stories using a structured framework.
Aspect-oriented requirements engineering (AORE) is a new methodology that can help us to further improve the analysis, structure, and cost of development of software requirements. The second part of this two-part series focuses on the AORE specification techniques.
Aspect-oriented requirements engineering (AORE) is a new methodology that can help us improve the analysis, structure, and cost of development of software requirements. AORE does not replace but rather complements any of the existing requirements methodologies. This two-part paper explains to software practitioners the AORE concept, illustrates how it can be applied on software projects, and discusses the benefits of AORE. Part I focuses on the AORE analysis techniques.
You don't have to be Giorgio Armani to fashion effective use cases. Use case patterns can provide you with a vocabulary to help you describe and judge the quality of your use cases. Find out how you can use these patterns to improve your requirements modelin
In this interview, Michael Harris, the president and CEO of David Consulting Group, explains his five-step Value Visualization Framework. He discusses how he came up with the idea, how it can help your team right now, and its similarities to the agile methodology.
Geolocation enhances the experience of many services and provides users with customized results based on their current location. Many people don’t realize what an important role geolocation can play in locating their favorite beer—and Untappd, a mobile application around beer discovery...
Although usability and user experience may seem synonymous, they are separate and much different concepts. While usability is well defined in standards, UX has no agreed upon definition because it relates to a more nebulous attribute-user satisfaction. Both are, however, key ingredients for successful system deployment. Because they don’t know how to measure and evaluate UX, many teams ignore this important attribute until the end of development. Philip Lew discusses how to model both usability and UX by breaking each attribute down into measurable characteristics-learnability, user effectiveness, user efficiency, content quality, user errors, and more. Phil shows you how to derive measurements and metrics that your development and team can employ to benchmark, analyze, and improve both usability and UX.
Use cases are hard to test because they do not have a standard format or style, and lack coherent structure. This is due in part to the need for a standard definition in UML, which defines the graphical part but not the textual part. In this session, Jim Heumann pinpoints the issues related to testability of use cases and introduces a testable style for writing use cases, a process used extensively and successfully by IBM Rational Software. Based on the testable use case writing technique, you will learn how to create test cases from these use cases.
How to make a use case more understandable and testable
