This paper presents two case studies performed by applying a strategy, named Joint Evolution of business Processes and software Systems (JEPS), for innovating business processes and their supporting systems. JEPS integrates measurement, decision-making, and critiquing techniques for analyzing business processes, identifying activities and software systems to be innovated, and mapping critiques onto specific innovation actions. JEPS is supported by a software environment, named WebEv+, for managing the assessment and evaluation tasks, and the modeling and critiquing of the business processes. The paper discusses two case studies regarding two different organizations in the Local Government domain. The analysis of the organization highlighted improvement goals and technological enhancement needs, and permitted the identification of the business processes and software systems to be evolved.
