Sometimes, a request might involve multiple technician work. In that case, the request can be divided into several tasks and each task can be assigned to a technician/group.
For example, consider a scenario where a new employee joins the organization. There is a list of tasks that need to be performed such as seating location, providing a computer/laptop, installing necessary software, connecting telephone links, entering his/her name in the active entry and so on. These operations can be considered as separate tasks and be can assigned to different technicians.
