The Relationship
TBM needs ITAM data (SaaS inventory) and FinOps data (cloud costs). FinOps needs TBM context (which business unit benefits from this cloud cost reduction?). ITAM needs TBM (what is the total cost of ownership of this asset?). All three are necessary; none is sufficient.
Common Mistakes
- Buying a FinOps tool and expecting it to solve TBM problems (it won't).
- Building TBM without cloud cost integration (your biggest cost category goes unmeasured).
- Running ITAM without TBM (you know you own the asset but not what it costs to maintain).
All three are necessary TBM needs ITAM data and FinOps data. FinOps needs TBM context. ITAM needs TBM for total cost of ownership. None is sufficient on its own.
“TBM, FinOps, ITAM. If you're only doing one, you're missing 2/3 of the picture.”
