This article presents QualDev-Software Process Improvement (SPI), a specific methodology to help mana- gers of small and emerging business or internal software development departments to implement the Capability Maturity Model Integration (CMMI). The aim of this methodology is to increase competitive- ness of these groups by letting them offer more quality in their products, and have better productivity. QualDev-SPI is based on three principles: (i) small steps for improvement aligned with the develop- ment projects; (ii) lightweight processes supported by tools, and (iii) short term view of the benefits. The methodology includes an organizational improvement model, a matrix of levels of achievement of practices, and a road map with a standardized definition of processes and support tools to facilitate its implementation.
