Ubiquitous computing is considered as enabler for linking everyday life with information and communication technology. However, developing pervasive and mobile applications that provide personalized user assistance still constitutes a challenge. Mobile application scenarios are diverse and encompass domains like healthcare, logistics, and sales. For their support two fundamental technologies with increasing maturity are emerging: development frameworks for mobile devices and light-weight process engines. Their integrated use, however, is in a rather premature state. Generally, the use of a process engine for supporting mobile collaboration raises many challenging issues. This paper picks up some of these challenges and shows how we have coped with them in the MARPLE project. MARPLE targets at a tight integration of process management technology with mobile computing frameworks in order to enable mobile process support in advanced application scenarios. We give insights into the MARPLE architecture and its components.In particular, we introduce the MARPLE process engine, which enables light-weight as well as flexible process support on mobile devices. This will be key for mobile user assistance in advanced application scenarios
