Software Process Improvement (SPI) is the modification of current software process methods in many software development organizations. Its aim is to improve the organization's ability to produce better software products (Humphrey, 1990).
Competition has become more and more fierce, customers are demanding higher quality at lower prices and profit margins seem to be falling especially in times of crisis. An efficient and effective strategy to become more competitive is to adopt continuous improvement methodologies. Quality is more than making things without errors. It is about making a product or service meet the individual perception of a customer about the quality or value. (Dumitrescu & Dumitrache, 2011)
