A consistency assessment system for assessment of consistency of a software product includes a mapping module to obtain a plurality of configuration elements associated with the software product being developed, where each of the plurality of configuration elements influence software product development. Each of the plurality of configuration elements pertains to one of a plurality of element categories influencing software product development. The mapping module further identifies based on one or more identifiers, association of at least one configuration element from among the plurality of configuration elements with at least one another configuration element from among the plurality of configuration elements. Upon identification, an assessing module determines a requirement consistency index (RCI) for assessment of consistency of the software product. The RCI indicates an overall consistency of the software product.
