Business apllications consumed by multiple production sites

[sylvainbarr]

Hi, I need to solve a problem with one of my customer, they want to represent what production site (divisons or BU) uses what business application, this is the conceptual model we have worked with the EA groups: 

we have created an M2M table to associate a service instance to multiple locations, but a location is not necessarly a production facility. Also I was thinking about using BSO, one BSO per site, and create the relation within the CSDM view of Service instances. so my questions are:
1- does the model above make sense, anything missing, is it in line with CSDM?

2- Does the BSO approach a valide one?

Any suggestions are appreciated

Thanks

Hi Silvain, 

you can have 1 BSO for an Application Service Instance that is Subscribed by a production site (location of location_type Site).  There can be multiple locations (Production Sites) subscriptions to the same Application Service Instance.
If there are multiple Application Service Instances then you will have multiple BSOs as well.
If there is 1 Application Service Instance but you have multiple Service Levels in your offering, than you might have multiple BSOs as well. 

There is not a need to make a BSO per location, you can do so with subscriptions as well. 

BR,
Barry

Hi @sylvainbarr 

I agree with @Barry Kant - resist the temptation to twist the model to fit a use case. If your solution isn't what a CSDM object was designed for, find an alternative. In this case, the reality is that these sites use (subscribe to) the Service Instance, so a Subscribed by Location makes most sense to me.

It is however not 100% clear what a production facility is in your question. Does it represent a single user base that consumes that service differently? If so, and especially if different levels of service apply, then you could make a case for separate BSOs.

I hope this helps!
