Large-Scale Requirements Analysis Revisited: The need for Understanding the Political Ecology of Requirements Engineering

This paper addresses the political nature of requirements for large systems, and argues that requirements engineering theory and practice must become more engaged with these issues. It argues that large-scale system requirements is constructed through a political decision process, whereby requirements emerge as a set of mappings between consecutive solution spaces justified by a problem space of concern to a set of principals. These solution spaces are complex socio-technical ensembles that often exhibit non-linear behaviour in expansion due to domain complexity and political ambiguity. Stabilisation of solutions into agreed-on specifications occurs only through the exercise of organisational power. Effective requirements engineering in such cases is most effectively seen as a form of heterogeneous engineering in which technical, social, economic and institutional factors are brought together in a current solution space that provides the baseline for construction of proposed new solution spaces.
