Software organizations aim to improve their processes to increase their productivity, competitiveness and performance. Although numerous standards and models have been proposed, their adoption among small organizations is hard due to some size mismatches and to lack of experienced process engineers, which forces them to hire (expensive) external consultants. This article describes the Tutelkan SPI Framework, which proposes a three-fold approach to this problem: (1) providing a library of reusable process assets, (2) offering composition tools to describe small organizations processes using these assets, and (3) systematically training small organization focused consultants for these library and toolset. The framework has been successfully piloted with several Chilean small companies, and the library and tools are open and freely available.
