3. Requirements engineering consists of activities that deal with the gathering, analysis, validation, documentation and maintenance of the set of requirements for a system and implements them into the software development process (Pandey, Suman, & Ramani, 2010; Siddiqi, 1996). Requirements are the properties, i.e. features or qualities, that must be possessed by the system or system component that is to be delivered, in order to satisfy customer needs (Jalote, 1997).

7.  After the publication of the requirements engineering process model, the three authors cooperated on:  A Framework for Modelling Software Requirements  An Approach to Information Requirement Engineering  Security Requirement Engineering Issues in Risk Management  The proposed RE process is general  In some situations a more specialized and detailed approach is required.  There are no publications available that describe the application of the RE process.

8.  Suitability for a specific software development context is not described by Pandey et al.  Is the RE process appropriate for Market Driven Requirements Engineering (MDRE)?  Analysis of relevant papers show that only parts of the process are usefull in MDRE context:  Karlsson, L., Dahlstedt, A., och Dag, J.
