Lecture Software engineering - Chapter 30: Software process improvement

Chapter 30 - Software process improvement. Software process improvement encompasses a set of activities that will lead to a better software process and, as a consequence, higher-quality software delivered in a more timely manner. | Chapter 30 Software Process Improvement Slide Set to accompany Software Engineering: A Practitioner’s Approach, 7/e by Roger S.

What is SPI? SPI implies that elements of an effective software process can be defined in an effective mann an existing organizational approach to software development can be assessed against those elements, and a meaningful strategy for improvement can be defined. The SPI strategy transforms the existing approach to software development into something that is more focused, more repeatable, and more reliable (in terms of the quality of the product produced and the timeliness of delivery). SPI Framework a set of characteristics that must be present if an effective software process is to be achieved a method for assessing whether those characteristics are present a mechanism for summarizing the results of any assessment, and a strategy for assisting a software organization in implementing those process characteristics that have been found to be weak or missing. An SPI framework assesses the “maturity” of an organization’s software process and provides a qualitative indication of a maturity level. Elements of a SPI Framework Constituencies Quality certifiers Quality(Process) --> Quality(Product) Formalists Tool advocates Practitioners Reformers Ideologists Maturity Models A maturity model is applied within the context of an SPI framework. The intent of the maturity model is to provide an overall indication of the “process maturity” exhibited by a software organization. an indication
