IT Benchmarking
What is IT Benchmarking?
IT benchmarking is the practice of comparing an organization's technology costs, staffing, service levels and practices with those of peer organizations or industry standards to judge performance and find improvement opportunities.

IT benchmarking answers a question that internal data alone cannot: is our technology spending reasonable compared with others like us? Organizations compare measures such as IT spending as a percentage of revenue, IT cost per employee, the cost of specific services, staffing ratios and service levels with peer groups or industry data. The results show where the organization spends more or less than peers and where its practices differ.
Benchmarks are useful for setting targets, building business cases and testing assumptions, but they are easy to misread. Differences in business model, scale, strategy and how costs are classified can make a fair comparison difficult. For IT financial management, benchmarking works best when the organization's costs are classified using a standard model, such as the TBM taxonomy, and when results are treated as a starting point for questions rather than as verdicts.
Definition of IT Benchmarking
IT benchmarking is the systematic comparison of an organization's technology performance and costs with external reference points. These may include peer organizations of similar size and industry, published industry averages or best-practice standards.
Benchmarking can be performed at different levels: the whole IT function, specific cost categories or IT towers, individual services, or processes such as service desk operations.
Common Benchmark Measures
Top-level measures include IT spending as a percentage of revenue, IT spending as a percentage of operating expense and IT cost per employee. These give a broad view of how much the organization invests in technology relative to its size.
More detailed measures include the cost per unit of specific services, such as cost per service desk ticket, cost per server or cost per user for collaboration tools, along with staffing ratios and the split of spending between running the business and changing it.
Quality measures, such as service availability, ticket resolution times and user satisfaction, are important to include, since low cost alone does not indicate good performance.
Sources of Benchmark Data
Benchmark data comes from research and advisory firms, industry associations, consulting firms that run benchmarking studies, and peer networks where organizations share data directly.
Detailed benchmarking studies typically require the organization to submit its own data in a standard format, which is then compared with a peer group selected for similarity.
The quality of the comparison depends on how well the peer group matches the organization and how consistently costs are classified across participants.
Importance of IT Benchmarking in IT Financial Management
Without external comparison, it is difficult to know whether technology costs are high, low or reasonable. Benchmarks provide that context.
They are often requested by executives and boards when reviewing the IT budget, and they support decisions about where to invest or save. A CIO who can show how the organization's costs compare with peers, and explain the differences, is in a stronger position in budget discussions than one who can only describe internal trends.
Used well, they also help IT leaders explain their spending in terms that business leaders and investors recognize.
Identifying Opportunities
Benchmarks highlight areas where the organization spends significantly more than peers, which may indicate inefficiency, or significantly less, which may indicate underinvestment and future risk.
Comparisons at the service or tower level are usually more actionable than top-level ratios, since they point to specific areas to investigate, such as unusually high costs for storage or end-user support.
Benchmarks can also support IT cost optimization by setting realistic targets based on what peers achieve.
Limitations
Differences between organizations can make benchmarks misleading. A company that relies heavily on digital products will naturally spend more on technology than one in a less technology-intensive business, even within the same industry.
Differences in how costs are classified, such as whether technology spending outside IT is included, can distort comparisons. Benchmarks also show where an organization stands, not why or whether its position is appropriate for its strategy.
For these reasons, benchmarks should prompt investigation rather than automatic cost targets.
How to Run an IT Benchmarking Exercise
A useful benchmarking exercise involves defining its purpose, preparing consistent data, choosing appropriate comparisons and interpreting the results carefully.
The effort required depends on the level of detail, from a quick comparison of top-level ratios to a full study of services and processes. A full study can take several months and requires significant input from IT finance and service owners, so its scope should match the decisions it is meant to inform.
Preparing the Data
Decide what questions the benchmark should answer, such as whether infrastructure costs are competitive or how the IT budget compares with peers. This determines the measures and level of detail needed.
Classify costs using a standard model, so they can be compared with external data. Include technology spending outside the IT department where possible, since peers may include it.
Gather the volumes needed for unit costs, such as users, devices, servers and tickets, and check them for accuracy. Errors in volumes distort unit costs just as much as errors in spending, and are often harder to spot.
Interpreting Results
Compare results with a peer group that matches the organization's industry, size and business model as closely as possible. Look at ranges and medians rather than single averages.
For each significant difference, investigate the reasons. A higher cost may reflect a deliberate choice, such as higher service levels or a recent investment, rather than inefficiency.
Present results with context, explaining which differences are expected and which point to opportunities, and repeat the exercise periodically to track progress.
Examples of IT Benchmarking in IT Financial Management
The examples below show how benchmarks inform decisions.
Both use illustrative figures.
In each, investigating the reasons for a difference mattered more than the difference itself. The first uses a top-level ratio, and the second uses a service-level unit cost, which is usually more actionable.
A Top-Level Comparison
A board asks whether the company's IT budget is too high. IT spending is 4.8% of revenue, compared with a peer median of 3.9%. Further analysis shows that the company is two years into a major platform replacement, which accounts for most of the difference.
Excluding the program, spending is 3.7% of revenue, close to the peer median. The board accepts the explanation and asks for the comparison to be repeated after the program ends. Without the breakdown, the headline figure might have led to a cut in the program's funding.
A Service-Level Comparison
An IT organization benchmarks its service desk. Its cost per ticket is $28, compared with a peer median of $19, and it handles more tickets per employee than most peers.
Investigation shows that many tickets are password resets and access requests that peers handle through self-service. Introducing self-service for these requests reduces ticket volume by 30% and brings the cost per ticket closer to the peer range.
Conclusion
IT benchmarking compares an organization's technology costs, staffing, service levels and practices with peers or industry standards. It provides context for judging whether spending is reasonable and where improvements are possible.
In IT financial management, benchmarking supports budgeting, cost optimization and conversations with executives and boards. Using a standard cost model, choosing appropriate peers, including quality measures and investigating the reasons for differences help organizations get meaningful insights rather than misleading comparisons.

TBM Taxonomy
The TBM Taxonomy is the TBM Council's standard model for classifying technology costs. It organizes spending into cost pools, resource towers, solutions and consumers so costs can be compared and traced.
IT Towers
IT towers are groups of technology resources, such as compute, storage, network and end-user devices, used to organize IT costs in TBM. The current TBM Taxonomy calls them technology resource towers.
IT Cost per Employee
IT cost per employee is a measure of technology spending calculated by dividing an organization's total IT costs by its number of employees, commonly used to compare IT investment across organizations and over time.
IT Cost Optimization
IT cost optimization is the continuous practice of aligning technology spending with business value, reducing waste and inefficiency while protecting or increasing investment in the capabilities that matter most.
