"If you dont know where you are going, any road will get you there." Alice from Alice in Wonderland was told this obvious piece of wisdom when she asked for directions. We all know this wisdom from navigating through the fog of insufficient requirements when working on projects. Clear goals can be achieved; unclear goals are sure to be missed. Requirements engineering (RE) is the disciplined and systematic approach (i.e., "engineering") for elicitation, documentation, analysis, agreement, verification, and management of requirements while considering market, technical, and economic goals. "Disciplined" is about culture, and "systematic" demands process and tools, which is our focus here.
