Example of a Scrum of Scrums scenario

Now let us take an example of a scenario where scrum of scrums can be used. This is a very small example consisting of only three teams for keeping it simple.

Let’s assume that the task has to fulfilled which says that any kind of reports prepared in clinical labs should be received by the doctors automatically for the patients they register. Three teams strive to obtain this common goal.

TeamA: The source end , the clinical laboratory which will be sending the report (e.g. blood sugar ). They should send the message in a particular format with accepted healthcare standards of laboratory. TeamB: The team in between acting as a message bus to receive from source and send to destination. This team has to understand the source format of message and convert to the format understood by the destination. TeamC: The receiving end, the doctor’s desktop.The results in the message should be seen as a form on his machine.

Now all these teams need to meet on frequent basis to achieve this use case and not only make sure that their part is done but also ensure that the overall flow of the message is smooth. They meet on periodic basis and make sure to share their achievements and ask questions such as what is needed by other teams and working on what next will be most beneficial.
