## 8. FAQ - IT Cost Optimization

### How to identify waste in my IT budget?

      To identify waste, perform a **complete audit of all costs**: map each expense, analyze actual usage vs Capacity, compare to industry benchmarks, and identify significant gaps. Capacity Planning tools like [Workload](/Capacity-Planning-dsi) enable automatically identifying over-allocations and under-utilizations.

### How to optimize costs without impacting quality?

      To optimize without impacting quality, follow these principles: **identify waste** before cutting, **optimize Processes** to reduce costs, **negotiate contracts** without reducing services, **maintain minimum SLAs**, and **measure quality impact** of each optimization. Progressive approach with tests on limited scopes.

### What is the typical IT cost breakdown?

      Average IT cost breakdown is: **Personnel (55-65%)**, **Infrastructure (20-25%)**, **Tools/Licenses (8-12%)**, **Outsourcing (10-15%)**, and **Other (4-6%)**. This breakdown varies by IT department size: small IT departments have more personnel (60-70%) and outsourcing (15-20%), large IT departments have more infrastructure (25-30%) and tools (12-15%).

### What are the main Types of IT waste?

      The 7 main Types of IT waste are: **Underutilized resources (15-20%)**, **Redundancies and duplications (10-15%)**, **Inefficient Processes (20-25%)**, **Over-sizing (10-12%)**, **Hidden costs (15-18%)**, **Excessive external dependencies (8-10%)**, and **Failures and rework (12-15%)**. Total average impact is 20-30% of IT budget.

### What KPIs to use to track cost optimization?

      Key KPIs to track optimization are: **IT cost per employee** (benchmark: €8,000-12,000/year), **Optimization rate** (target: 15-25% over 12 months), **Optimization ROI** (target: > 200%), **Identified waste rate** (benchmark: 20-30%), and **Cost reduction rate** (target: -5 to -10% per year). Track these KPIs monthly with dashboards.

### How to optimize cloud costs?

      To optimize cloud costs: **Right-sizing** instances (savings 20-30%), **Reservations** for stable workloads (savings 30-40%), **Automatic shutdown** of unused resources (savings 15-25%), **Storage optimization** (savings 20-40%), and **Multi-cloud negotiation**. Use cloud monitoring tools (AWS Cost Explorer, Azure Cost Management) to identify opportunities.

## 9. Capacity Planning: Link Between Workload Visibility and Cost Control

      The largest IT cost line is **personnel (55–65%)** — yet most IT departments lack real-time visibility into whether that spend matches actual project demand. Capacity planning closes this gap by connecting budget to utilization.

      CIOs who deploy capacity planning before cost-cutting report three measurable outcomes:

        - **15–20% reduction in underutilized resources** identified within the first quarter

        - **30% fewer overload incidents** (overtime, contractor rush fees, missed deadlines)

        - **40% better budget visibility** when presenting headcount and project trade-offs to the CFO

      Instead of cutting blindly, use capacity data to answer: Which projects can we defer? Where are we paying for skills we don't need this quarter? Which teams are at 110% load and driving hidden costs?
