In certain cases, an application user may not be able to complete an assigned task, without collaborating with other users. For instance, in the case of BPO applications, agents working on BPO tasks must collaborate with their senior agents or clients before completing their tasks.
Collaborative tasks allows users to complete their work by collaborating with other users (or groups).
When a task performer chooses you (or your group) as a collaborator, the collaborative task appears in your Task List page.
