Abstract An ever-increasing demand for information systems in the last few decades brought many new opportunities but also presented new challenges for companies in the landscape of doing business globally. In these terms, software systems need to adapt almost instantaneously to new requirements, opportunities, and customer expectations. Process-aware systems have become integral part in business information system solutions, finding their place at different locations. This paper presents a workflow engine - NewWave , created with the goal to enable an extensible workflow management system, to facilitate easy specification and implementation of application business logic with focus on simplicity and immediate feedback. Through seamless integration with Pharo applications, libraries, tools, and leveraging Pharo's live environment, the NewWave enables users to create dynamically adaptable process models to facilitate the flexible adaptation of business logic.
