PUTTING REQUIREMENT MANAGEMENT INTO PRAXIS - DEALING WITH NONFUNCTIONAL REQUIREMENTS

Sound requirement management is the single most relevant technique to ensure that the need to provide customer-oriented solutions in a defin ed timeframe with limited budget can be matched with future safe evolu tion of system families. The last objective is especially closely rela ted to nonfunctional requirements, We will show in this paper how requ irement management for nonfunctional requirements is put into practice , thus integrating and exemplifying different key elements of requirem ent management, namely specification, conflict resolution, requirement tracing and progress tracking. Various practical examples are provide d from the application of these techniques to development of telecommu nication systems within Alcatel. The aspects of maintainability or rel iability are naturally discussed as such systems are built on re-used components. (C) 1998 Elsevier Science B.V.
