We address the assessment and improvement of the software maintenance function by proposing a maturity model for daily software maintenance activities: the Software Maintenance Maturity Model (SMmm). The software maintenance function suffers from a scarcity of management models to facilitate its evaluation, management, and continuous improvement. The SM mm addresses the unique activities of software maintenance while preserving a structure similar to that of the Capability Maturity Model integration (CMMi). It is designed to be used as a complement to that model. The SMmm is based on practitioners' experience, international standards, and the seminal literature on software maintenance. We present the model's purpose, scope, foundation, and architecture, followed by its initial validation.
