Abstract: “Software Process Improvement (SPI) can help the software practitioners to enhance their capabilities in the field of software engineering. Various models have been proposed in order to improve software process framework. However, implementation of such modules often requires huge cost involvement. Small and Medium sized Software Enterprises (SMEs), in Bangladesh, naturally fail to introduce or adapt such frameworks. So it has become a need of time to observe the Software Process scenario as a part of research activity which will ensure smoother transition to improved Process Framework. In this paper, various practical models and their practices in various SMEs and the importance of SPI system are highlighted and analyzed. Survey has been conducted to assess Real life practices with a view to compare with Benchmarks like Capability Maturity Model Integration (CMMI). This attempt also suggests a direction for minimum best practice that might be helpful for small and medium sized companie”
