But where are the laboratories for software engineering? They can and should be anywhere software is being developed. Software engineering researchers needs industry-based laboratories that allow them to observe, build and analyze models. On the other hand, practitioners need to build quality systems productively and profitably, e.g., estimate cost track progress, evaluate quality . The models of process and product generated by researchers should be tailored based upon the data collected within the organization and should be able to continually evolve based upon the organization’s evolving experiences. Thus the research and business perspectives of software engineering have a symbiotic relationship, From both perspectives we need a top down experimental, evolutionary framework in which research and development can be logically and physically integrated to produce and take advantage of models of the discipline, that have been evaluated and tailored to the application environment. However, since each such laboratory will only provide local, rather than global, models, we need many experimental laboratories at multiple levels. These will help us generate the basic models and metrics of the business and the science.
