Software is in constant evolution and many approaches have been suggested to study software maintenance productivity. This research reports on a process to design and implement a productivity model of legacy software based on the meas- urement of small functional enhancements using the COSMIC ISO 19761 international standard. Two motivations in- fluence this research: 1) understanding the productivity of the software maintenance process to help manage the cost of maintenance; 2) understanding the cost drivers that affect the software maintenance productivity. This research reports on an empirical study of a productivity measurement program implemented in a large banking legacy system.

I am full professor of Software Engineering at the University of Québec in Montréal, in its Software Engineering faculty. I have more than 30 years of Helthcare, Finance/Banking and Telecommunications IT industry experience, especially in Cloud Computing, Big Data, software acquisition, contracts, software quality assurance and business process management. I am more comfortable with open source, practical applications and technology transfer to industry.
Currently I concentrate on research projects. In the past I was the recipient of the ISO award for higher education in standardization in 2011, as well as the chair of the Software Engineering gratuate program and of the Software Engineering departement. I also published Software Engineering Books: Software Maintenance Improvement and Software Quality Assurance.
