Multi-tenant Software-as-a-Service (SaaS) applications share a single runtime instance among multiple customer organizations (tenants). To account for differences in tenant requirements, they have to support run-time customization. The latter turns these types of applications into a dynamic software product lines involving a wide range of software artifacts such as user interfaces, databases, web-services and business process or workflow definitions. This paper analyzes and compares the quality

The customization strategies are selected from an existing survey and the comparison criteria are derived from two essential characteristics of SaaS: it is (i) a business model aiming at "economies of scale", and (ii) a software delivery model with specific automation requirements. The comparative study shows that there is no single best strategy, and provides SaaS architects with support for making appropriate trade-off decisions when adopting a workflow customization strategy. As a by-product of this study, a number of points for future improvement and innovations in existing workflow technology are identified, which are exclusively relevant for multi-tenant SaaS applications.
