A Value-driven Approach for Software Process Improvement -- A Solution Proposal

Résumé : Software process improvement (SPI) is a means to an end, not an end in itself (e.g., a goal is to achieve shorter time to market and not just compliance to a process standard). Therefore, SPI initiatives ought to be streamlined to meet the desired values for an organization. Through a literature review, seven secondary studies aggregating maturity models and assessment frameworks were identified. Furthermore, we identified six proposals for building a new maturity model. We analyzed the existing maturity models for (a) their purpose, structure, guidelines, and (b) the degree to which they explicitly consider values and benefits. Based on this analysis and utilizing the guidelines from the proposals to build maturity models, we have introduced an approach for developing a value-driven approach for SPI. The proposal leveraged the benefits-dependency networks. We argue that our approach enables the following key benefits: (a) as a value-driven approach, it streamlines value-delivery and helps to avoid unnecessary process interventions, (b) as a knowledge-repository, it helps to codify lessons learned i.e. whether adopted practices lead to value realization, and (c) as an internal process maturity assessment tool, it tracks the progress of process realization, which is necessary to monitor progress towards the intended values.
