The 12 Days of Benchmarking - Day 7
On-budget project delivery
Yesterday we looked at delivering initiatives on time.
Today we look at the other side of delivery discipline:
đ Do you deliver digital initiatives within the budgets you commit to?
Because time and cost together define your credibility as a delivery organisation.
ďťż
What this metric is
On-budget project delivery measures the percentage of digital initiatives delivered within their agreed budgets.
In simple terms:
Of all your digital initiatives, how many stayed within budget?
It applies to projects, product enhancements, and major digital initiatives designed to deliver measurable business value.Â
ďťż
Why it matters
Budget discipline is not just about finance.
It reflects:
- how clearly you define requirements
- how effectively you manage risk
- and how mature your delivery capability is
Consistently going over budget can lead to:
- reduced trust from senior leadership
- pressure on future funding
- and increased scrutiny on IT investments
Strong on-budget performance shows that IT can be trusted to manage investment responsibly while delivering value.

What good looks like in practice
Organisations that perform well here typically show:
- Accurate and realistic cost estimates
- Budgets are based on clear requirements, good data, and realistic assumptions
- Strong financial governance
- Costs are monitored and controlled throughout delivery
- Changes are managed properly, with impacts to cost and time understood and agreed
- Teams have the technical and delivery expertise needed to avoid rework and inefficiency
- Transparent financial reporting
- Leaders have clear visibility of spend, risks, and forecasts
ďťż
Why projects go over budget
When performance is low, the root causes are often very consistent:
- Scope creep and uncontrolled change
New requirements added without adjusting the budget
- Inaccurate cost estimates
Caused by unclear requirements, limited historical data, or capability gaps
- Insufficient technical expertise
Leading to inefficiencies, rework, or redesign
- Unrealistic budgets
Set under cost pressure rather than based on reality
- Weak project or financial management capability
Particularly in areas such as resource, risk, and financial tracking
These are all identified as common drivers of poor on-budget performance in the PBM guidance.Â

How to improve it
If you want to improve on-budget delivery:
1. Strengthen cost estimation practices
Use historical data, reference models, and experienced estimators
2. Improve financial governance
Track costs regularly and act early when variance appears
3. Control scope and change rigorously
Ensure any change in scope is matched with a change in cost or timeline
4. Invest in delivery and financial capability
Develop skills in project, product, and financial management
5. Align budgets with reality
Ensure budgets reflect the true complexity and risk of the work
ďťż
A simple reflection
Look at your last 10 major digital initiatives.
How many were delivered:
- and delivered the expected value?
Because true delivery maturity means achieving all three.

Take part in the benchmarking
The ITIL Performance Benchmarking Model helps organisations understand how effectively they manage digital investment.
By contributing your data, you can:
- benchmark your financial delivery performance against peers
- identify where cost control is breaking down
- and improve how you plan and govern digital spend
