In this article I’m going to share something with you about sequential – and parallel tasks. During the implementation at customer X we encountered some challenges. Some processes are using sequential tasks and some needed a parallel approach. In this document you can find a solution for this.

Sequential tasks

We are using the sequential approach in the request fulfillment process.
Below you will find an example of these sequential tasks.


  • The end user is ordering a laptop by using Self Service portal
  • After he has filled in his requirements and clicks on the Order Now button, the following 6 tickets are created:
    • REQ12345; cart with 1 article in it
    • RITM56789; the requested item
    • TASK90121; approval by manager of the end user
    • TASK90122; order the laptop by the supplier
    • TASK90123; prepare the laptop to deliver to the end user
    • TASK90124; deliver the laptop and let him sing the delivery papers
  • The progress can be tracked-and-traced using the Self Service portal with the REQ and RITM number.
  • The TASK numbers are used internally by the IT department. We call them sequential tasks; after task 1 is completed, task 2 can start etc.

Note: when the 4 TASKs are completed the RITM and REQ tickets will automatically be closed.
