TMF 656 - Service Problem - Estimated Time to Restoration (ETR)

    Hello,

    I was looking for guidance on adding an estimated time to restoration/resolution (ETR) value to the service problem. At the moment I don't see an easy way to fit an ETR for service problem resolution in the object.

    Why include this in the service problem object? Well, it looks like stakeholders that consume service problem would like to have this information available so that it can be communicated to downstream systems and ultimately customers during trouble handling. Having a support person have a line of sight to the ETR would be advantageous in his workflow. As the service problem instance evolves and more events/insights are gained through correlation and time, the ETR would be changing to something a bit more precise based on rules and what we get from the network.

    Does anyone see reasons not to include an ETR type field in TMF 656? To me it makes sense if you have such information once you have diagnosed the problem.
    Does anyone have any opinions on where the value could go in the existing payload? I am a bit new to it and am trying to find the best place.

    Thank you all for sharing your thoughts.
    Marc

    Hi @Marc Landry,

    Thank you for your input. Yes, this certainly makes sense.

    Would you be able to raise an enhancement JIRA request for this? Please provide as much information as you can in the JIRA. Let me know if you need help in creating one. The JIRA will help to add this as a backlog item for future enhancement of the API.

    Good morning,

    Thank you for the quick reply. I would be happy to create a ticket. This being my first time would it be possible to share what board to post on? I am assuming this is the link (https://projects.tmforum.org/jira/secure/ManageRapidViews.jspa)?

    In the meantime, I may have to extend the model myself until gratified by the community. Would you have any guidance on this? I was thinking of creating another subresource for estimatedResolutionTime or using the extensionInfo for now.  I guess extensionInfo would be better for now until the community thinks about my request.

    Thank you.

    Use this link: https://projects.tmforum.org/jira/projects/AP/issues
    and make sure that you open the issue on the API Project, I suggest to use issue type Improvement.
    Good luck

    I only see the following projects when clicking create from the link you provided. Am I missing some permissions or something?


    Thank you

    Hi Mark,  you need to be a member of the API project first.  When you sign to TMForum.org, select collaboration project and then API project, this will take you to a community page (don't ask!) from which again you need to select Core Project Area and then TMF Open API project.  Once you sign up, your Bell Canada TMF point of contact will receive an email and will need to approve (unless he/she selected an automatic acceptance).  Once that is done, you will have access to the API project Confluence page, from which the link from Jonathan should work!

    Sorry, it's a bit convoluted, and I strongly recommend you bookmark the Confluence page once you have access, so you don't need to go through this every time you try to access the project!

    Hi Mark , check out the Trouble Ticket model, it has an attribute of the Trouble Ticket.  I see no reason why it would not be an attribute of the Service problem , similar to the Trouble Ticket.   If you have an associated Trouble Tickets as part of the Service Problem, I would suggest you will need logic to verify the ETR of the Trouble Tickets if that is what is driving the resolution process (the Trouble Ticket(s)).  Remember that there is a 1 to many association to Trouble Ticket , so one would need to resolve all TT.  The longest ETR from the TT(s) would be essentially the ETR of the Service Problem unless .. there are other activities outside of the Resource issues etc.. to address the Service Problem and there are no associated TT with those activities for resolution.

    From the TMF API SP for Reference:
    A trouble ticket represents a record used for reporting and managing the resolution of resource problems.
