Imprecise language makes understanding and, therefore, software verification more difficult. This article describes techniques for detecting and repairing vague and ambiguous software requirements.

Most people don't fully understand the complexities and scope of a software performance test. Too often performance testing is assessed in the same manner as functional testing and, as a result, fails miserably. In this four-part series we will examine what it takes to properly plan, analyze, design, and implement a basic performance test. This is not a discussion of advanced performance techniques or analytical methods; these are the basic problems that must be addressed in software performance testing.

A focused approach toward testing a product is important, but sometimes we discover information that we didn't anticipate at all. One of the key skills in testing is dynamically managing our focus; sharpening it sometimes and widening it at other times. If we vary our approaches, we might find something surprising and broaden our coverage.

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.
