What Is a Technology Total Cost of Ownership (TCO) Study?
A technology TCO study establishes what your technology actually costs — all of it, including the spend that never reaches the IT budget line — and identifies where that cost can be reduced without reducing capability.
At DAG Tech, the technology total cost of ownership study is a CxO™ Virtual CTO deliverable. It is frequently the one that pays for the rest of the programme, because most organizations are carrying more duplicated and unused spend than they expect.
Why the Real Number Is Always Higher
The IT budget is not the cost of technology. It is the portion of it that happens to be administered by IT:
- Departmental spend is invisible. Marketing, finance and operations each buy software directly, and none of it appears in the IT line.
- Internal labour is uncounted. Hours your staff spend on workarounds and manual reconciliation are real cost with no invoice.
- Downtime is never priced. Outages are discussed as incidents rather than as a recurring cost figure.
- Licences outlive users. Subscriptions renew for staff who left, at a rate nobody reviews.
- Overlap goes unnoticed. Three products covering the same capability, each bought by a different team.
How DAG Tech Runs a TCO Study
1. Build the Complete Cost Inventory
Objective: Find every line of technology spend, wherever it sits.
- IT budget lines, contracts and purchase orders.
- Accounts payable review by vendor and by category, to surface spend outside IT.
- Corporate card and expense analysis for departmental subscriptions.
- Cloud consumption by tenancy and by service, including idle resources.
- Licence entitlement against actual assigned and active usage.
2. Separate Direct and Indirect Costs
Objective: Count what is paid and what is absorbed.
Direct cost is straightforward: licensing, hardware, cloud, connectivity, support contracts, project spend. Indirect cost is where the study earns its keep — internal labour on manual processes, time lost to slow or failing systems, downtime, rework from data quality problems, and administrative burden. Indirect cost is estimated rather than invoiced, so the method and confidence level are stated for every figure.
3. Normalize the Figures
Objective: Produce numbers you can compare and forecast with.
- Cost per user, overall and by role type.
- Cost per site, adjusted for size and function.
- Cost per business capability rather than per vendor.
- Fixed versus variable split, so growth can be modelled honestly.
4. Identify and Quantify Savings
Objective: Turn analysis into a run-rate reduction.
Overlapping products, unused licences, over-provisioned cloud, out-of-date contract terms, support arrangements that duplicate a managed service, and manual processes with a clear automation case. Each opportunity is quantified with the effort and risk of realizing it, because a saving that requires a disruptive migration is not the same as one that requires cancelling a subscription.
What the Deliverable Actually Looks Like
The study is a document a CFO reads, so its structure matters as much as its arithmetic. Ours runs in eight sections.
Sections 1–3: Purpose, method and the cost inventory
What is in scope and the cost model used, where the figures came from and how they were validated, then the full inventory including shadow spend — which is usually the section that produces the first difficult conversation.
Sections 4–6: Direct costs, indirect costs and normalized figures
Direct and indirect cost broken out separately, then cost per user and per site. Every cost line carries the same fields:
- Category and vendor — what it is and who is paid.
- Annual cost — normalized to a yearly figure regardless of billing cycle.
- Cost owner — which budget it currently sits in.
- Entitlement versus active usage — what you pay for against what is used.
- Business capability served — so overlap becomes visible.
- Contract end date and notice period — when it can actually be changed.
- Direct or indirect — and for indirect, the estimation method and confidence.
Sections 7–8: Savings opportunities and the decision page
Each opportunity quantified with effort, risk, dependencies and the earliest date it can be actioned given contract terms. Then a decision page listing every numbered opportunity so leadership can select what to pursue, with the cumulative run-rate impact shown.
The decision page states the saving as an annual run-rate change rather than a one-off, because that is the number that matters at the next budget cycle.
Where the TCO Study Fits
The technology total cost of ownership study is a CxO™ Virtual CTO deliverable that pairs naturally with the technology assessment and vendor evaluation work, and provides the cost baseline for the digital transformation plan. It is most valuable ahead of a budget cycle, a renewal cluster or a consolidation decision.
Most organizations do not have a cost problem they refuse to fix. They have one they cannot see.
