What do I need Taxonomy Layers for?

[Eva Klaus]

I am starting off to create our IT Portfolio. What is the benefit of creating different Taxonomy Layers? To me, it seems they are rather getting into my way. When I create a node on Layer 2 or 3, I always need to create a parent node - that would be by Layer 1 or 2, though (which does not work). Is it good enough to work with only one layer?

Hi Spike, no, I gave in. Created 2 layers after all (including an "auxiliary layer" if I could not come up with any second layer making sense). Guess taxonomy nodes are useful for multi-company providers.

I did something similar. Mine went:

Portfolio -> Portfolio
Taxonamy layer -> Our main application
Taxonamy node -> Our Products
Service -> Categories where people raise stuff
Service Offering -> Subcategories

We already had all the categories and subcategories set up so it worked out OK. I don't think it's how it's meant to be used but with reporting I can now attribute incidents and request to one of our products or portfolios.

I'm also struggling with this and whilst browsing some of the resources on CSDM I noticed Service Now do recommend considering aligning with TBM taxonomy and it's possible this is why their Taxonomy module is designed like this.

TBM and CSDM are both currently at version 4 but there are some resources showing how it might map to Service Now for the previous versions which aren't massively different.

This video from a SN solutions provider also came out last month:

How to Get More Out of ServiceNow - CSDM and Service Taxonomy

Also on the off chance you hadn't tried it. You can install a plugin on a Non Prod to see an example of how SN might use layers\nodes: Service Portfolio Management Taxonomy Content Pack

I thought the last video was going to be helpful but then ended up glossing over what I really wanted to know.

I installed the Content pack on my PDI but again I didn't think it was that helpful if I'm honest. At least not to direct me for what I'm trying to achieve.
