Reconciling system requirements and runtime behavior

Abstract

This paper considers the problem of runtime system deviations from requirements specifications. Such deviations may arise from lack of anticipation of possible behaviors of environment agents at specification time, or from evolving conditions in this environment. We discuss an architecture and a development process for monitoring system requirements at runtime to reconcile the requirements and the system's runtime behavior.This process is deployed on three scenarios of requirements-execution reconciliation for the Meeting Scheduler system. The work builds on our previous work on goal-driven requirements engineering and on runtime requirements monitoring.
