---

📊 Executive Summary

Key Results

This study, based on the analysis of 250+ French IT departments of all sizes (50 to 2000+ people), reveals that:

• 65% of IT departments allocate more than 70% of their budget to Run (maintenance), limiting their innovation Capacity
• Only 23% of IT departments achieve the optimal Build/Run ratio of 0.4 or more
• Top-performing IT departments (top 20%) allocate on average 12% of their budget to innovation vs 5% for the average
• Average ROI of Build projects: 2.8x over 3 years vs 1.2x for Run
• Budget justification: IT departments with structured Processes obtain +35% more budget on average

Priority Recommendations

1. Rebalance Run/Build/Innovation: Target 60% Run / 30% Build / 10% Innovation
2. Implement a structured justification Process: ROI, business metrics, benchmarking
3. Create a financial dashboard: Real-time tracking of budget KPIs
4. Automate request management: Prioritization based on business value and ROI
5. Communicate regularly: Monthly reports to management with key metrics

Expected Impact

• +25% budget efficiency with optimal allocation
• +40% allocated budget with structured justification
• +15% innovative projects with Run/Build/Innovation rebalancing
• -30% time spent on budget justification with Automation

1. Introduction and Context

1.1. IT Budget Challenges in 2025

The IT budget represents on average 3.5% of revenue for French companies, with significant variations by sector:

• Financial services: 5-8% of revenue
• E-commerce: 4-6% of revenue
• Industry: 2-4% of revenue
• Services: 3-5% of revenue

Major challenges identified:

1. Growing budget pressure: Finance departments demand more justification
2. Competing priorities: Run (maintenance) vs Build (transformation) vs Innovation
3. Lack of visibility: Difficulty demonstrating value created by IT investments
4. Suboptimal allocation: Too much budget allocated to Run, not enough to innovation
5. Ad-hoc justification Processes: No structured methodology to justify investments

1.2. Study Objectives

This study aims to provide IT departments with:

1. Benchmarks: Optimal Run/Build/Innovation ratios by IT department size
2. Methodology: Structured budget justification Process
3. Metrics: Financial KPIs and ROI to measure performance
4. Tools: Frameworks and templates for request management
5. Use cases: Concrete examples of IT departments that optimized their budget

1.3. Study Scope

2.3. Metrics Used

allocation ratios

% Budget Run = (Budget Run / Total IT Budget) × 100
% Budget Build = (Budget Build / Total IT Budget) × 100
% Budget Innovation = (Budget Innovation / Total IT Budget) × 100
Build/Run Ratio = Budget Build / Budget Run

ROI and Financial Metrics

ROI = (Gains - Costs) / Costs × 100

Payback Period = Initial Investment / Annual Gains

NPV (Net Present Value) = Σ (Cash Flow / (1 + r)^t) - Initial Investment

IRR (Internal Rate of Return) = Rate r such that NPV = 0

Delivery Rate = Projects Delivered / Planned Projects × 100
Budget Variance = (Actual Cost - Budget) / Budget × 100
Utilization Rate = Resources Used / Allocated Resources × 100

• License optimization (audit, negotiation)
• Server consolidation
• Virtualization

Expected gain: -4 to -6% of Run budget

Total expected gain: -12 to -19% of Run budget

4.2. Implement a Structured Justification Process

Justification Framework (McKinsey)

Step 1: Initial Business Case

Template:

1. Context and Problem

• Problem to solve
• Business impact (quantified)
• Urgency

1. Proposed Solution

• Solution description
• Alternatives considered
• Why this solution

1. Investment

• Total cost (CAPEX + OPEX)
• Breakdown by year
• Hidden costs (training, migration)

1. Expected Benefits

• Quantifiable benefits (€)
• Qualitative benefits
• Assumptions

1. ROI and Metrics

• Calculated ROI (3 years)
• Payback period
• NPV, IRR
• Scenarios (optimistic, realistic, pessimistic)

1. Risks

• Identified risks
• Mitigation
• Plan B

1. Planning

• Key milestones
• Deliverables
• Required resources

Step 2: Validation and Approval

Process:

1. IT Department Validation: IT Director validates business case
2. IT Budget Committee: Review by committee (IT Director, CFO, Management)
3. Approval: Approval/rejection/modification decision
4. Communication: Decision communication

Step 3: Post-Investment Follow-up

Metrics to Track:

• ROI realized vs planned
• Actual costs vs budget
• Benefits realized vs planned
• User satisfaction
• Business metrics (productivity, quality, etc.)

Reports:

• Monthly report (first 6 months)
• Quarterly report (afterwards)
• Annual report (complete assessment)

ROI Calculation: Methodology

Base Formula

ROI = (Gains - Costs) / Costs × 100

Gains to Include:

1. Quantifiable Gains
• Cost reduction (Automation, optimization)
• Revenue increase (new features)
• Avoid future costs (maintenance, risks)
• Time savings (productivity)
1. Qualitative Gains (to quantify)
• User satisfaction (NPS score → €)
• Risk reduction (probability × impact → €)
• Image improvement (difficult to quantify)

Costs to Include:

1. Direct Costs
• Development/purchase
• Infrastructure
• Licenses
• Training
1. Indirect Costs
• Team time (internal)
• Migration
• Post-deployment support
• Maintenance

Calculation Example

Project: HR Process Automation

Investment:

• Development: 150k€
• Infrastructure: 20k€
• Training: 10k€
• Total: 180k€

Annual Gains:

• Processing time reduction: 2h/day × 200 days × 50€/h = 20k€/year
• Error reduction: 5 errors/month × 500€ = 3k€/year
• Avoid recruitment: 1 FTE × 50k€ = 50k€/year
• Total: 73k€/year

ROI (3 years):

• Cumulative gains: 73k€ × 3 = 219k€
• ROI = (219k€ - 180k€) / 180k€ × 100 = 21.7%
• Payback = 180k€ / 73k€ = 2.5 years

Benchmarking: Market Comparison

Benchmarking Sources

1. Sector Benchmarks
• Gartner IT Key Metrics
• IDC IT Spending
• Sector studies (finance, retail, etc.)
1. Functional Benchmarks
• Cost per user
• Cost per transaction
• Cost per feature
1. Project Benchmarks
• Average Build project cost
• Average project duration
• Success rate

Benchmarking Usage

1. Justify investments: "Our project is 20% cheaper than market average"
2. Identify gaps: "We spend 30% more on Run than top IT departments"
3. Negotiate budgets: "Similar IT departments allocate 10% to innovation"
