Application lifecycle management (ALM) systems, used to support software development processes, can be composed from various components depending on the need of company. In this paper we focus on benefits of establishment of cross-tool interoperability with specific regard to heterogeneous platforms. We discuss how the different components can be connected for systemic tool collaboration with the help of Open Services for Lifecycle Collaboration (OSLC). This helps to improve traceability and consistency. Furthermore, workflow can be generated to correct the traceability gaps, consistency problems and even to implement modifications. Moreover, we present how the workload of developers can be decreased by integrating revision control system and development environment with the existing ALM system.
