Repost from the other community site :

I'm wondering what others would do or have done to address the following scenario:

You have technology cost transparency in place for showback and IT Planning on top and then another area of the business wants cost transparency and IT Planning as well. They're a separate division but they have technology spend within their books.

Do you:

1) Incorporate their spend into your CT costing for technology but identify the cost stream as a division or similar and then use a Division filter on all relevant reporting?

2) Stand up a separate CT project specific to the division so they can have the full scope of costing and reporting. Then use a cross-project reference to bring their contribution of application costs into your technology CT project for an inclusive app TCO perspective?

3) Some 3rd option I haven't considered?

Interested in pros, cons, and alternative approaches.  In this new forum space it appears I no longer have friends or followers <sad face> but fingers crossed you all have some fantastic ideas to share.

1 Con would be the operational overhead of running 2 separate projects. If the business has shared functions such as IT , Finance, HR etc then a lot of the data sources, config and reporting is potentially the same. You could setup datalink to transfer between projects, but you may still be duplicating a lot of very similar things. A better way might be a business unit identifier as a filter on the reports.
