Market driven requirements elicitation via critical success chains

Elicitation of requirements becomes more difficult as usually consumers do not explicitly know what they want and it is difficult for them to express their ideas. To support different views of product development, such as project management and design, the method should present requirements in a ´rich enough´ way to avoid overloading management but in the same time giving designers the detailed information they need. Requirements engineering should be easy to integrate to the software development process. To this end we have constructed a support environment for the method within Metaedit+ Meta CASE tool to present and manage the requirements. We have developed a new method that tries answering the complexities of development process. We based our method on critical success chains (CSC) method, that includes a top-down approach of planning but also wide participation of IS customers to get rich information. CSC aggregates the results of many individual interviews into meaningful graphical models of what is important about a potential system. CSC is extended with customer segmentation and lead user concepts from marketing.
