A Look at Application Prototyping with easyPilot

This application tool allows non-programmers to produce working prototypes of Windows, or Web-based, database-driven applications. Read on to find out how this new tool makes protoyping a viable part of the IT software development process.

Are You Listening?

Chances are you won't be able to deliver on everything your customer wants. Asking good questions at the beginning of a project can help you determine where your customer wants to go. Although you may not be able to give them everything they want, if you are able to deliver the top ten things on a list of fifty items you've still delivered value. Keeping the lines of communication open is essential to helping you achieve your project goal.

A Look at Rational's RequisitePro

Creating requirements involves tracking and documenting all of the criteria for a system's success. A requirements management tool, such as IBM Rational's RequisitePro, can support this effort. While the tool won't verify that the requirements are consistent, correct, complete, relevant, coherent, and testable, it can help manage the task more efficiently by allowing you to document, track, and maintain the requirements in an automated fashion.

Ellen Gottesdiener on Requirements Exploration and Modeling

Translating customer requests into software requires exploration, learning, and discovery. As such, this Reference Point lists resources you can use to learn more about requirements exploration and modeling. Ellen Gottesdiener—a recognized authority on software requirements—provides her top recommendations for books, journals, and online resources on the subject.

Gathering Users for Great Requirements

If you buy a hammer, you are not considered a master carpenter automatically. The same holds true for tool knowledge alone solving requirements problems. Kelley Schmidt shares the biggest lesson she learned on a project: commercial process and tools alone cannot lead to project success.

Analyzing Requirements Bugs

Analysis of bug reports from previous projects tells us about our most frequent errors, and can help us improve. But very few companies spend the time to analyze bugs from completed projects. Otto Vinter and Soren Lauesen explore using bug reports to improve the software development process.

Visual Modeling with Rational Rose

Darren Pulsipher looks at Visual Modeling with Rational Rose. He concludes: "Rose is far from the perfect Visual Modeling tool, but it is definitely one of the best OO tools on the market, and the most popular. Rational Software has done a great job in supporting its tools with user conferences, training, professional services, and seminars."

Are Your Requirements Complete?

Every system contains at least one (and probably more) set of requirements that fits into one of these categories: the functional who, what, where, when, why, how, and the nonfunctional design and project constraints. No one method or technique captures all requirements, but this approach can assist quality engineers in identifying missing requirements. Our objective is to spot the gaps in the requirements sets—just as a Tetris player spots gaps in those moving blocks—as soon as possible.

Learning from Pathfinder's Bumpy Start

Steve March discusses problems experienced by the Mars Pathfinder. He imparts the following lessons: 1) design defensively in the face of complexity; 2) design defensively for post-shipment problems; and 3) beware of best cases.
