To make the business goals and strategies clear, the GQM Strategies add several extensions to the GQM model. Business goals like increasing customer satisfaction, gaining market share, cutting production costs, considering the context, and making assumptions are dealt with by developing strategies. The organisation defines and incorporates sequences of actions required to complete the goals into strategies to accomplish a particular aim. Links are made between every objective and the strategy it promotes. Models that are used to interpret data to identify whether the predetermined goals at all levels are met are called interpretation models. Assumptions must be taken into account while estimating unknowns as they may have impacts on how the results are interpreted (Basili et al., 2007; Trendowicz et al., 2014).
