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).
