Introduction: The IT Skills Management Challenge

In a context of accelerated digital transformation, IT departments face a major challenge: maintaining and developing their teams' skills in the face of emerging new technologies (cloud, AI, DevOps, cybersecurity) while managing existing skills (development, infrastructure, support).

This strategic study, conducted in 2026, analyzes practices from over 180 French IT departments of various sizes (from 20 to 500+ people) to identify best skills management strategies, gap identification methodologies, and optimal approaches for skills development.

1. Identifying Skill Gaps

1.1 Mapping Current Skills

The first step is to establish a complete inventory of skills present in your IT department:

• Technical skills: Programming languages, frameworks, tools, certifications
• Business skills: Areas of expertise (e-commerce, finance, healthcare, etc.)
• Transversal skills: Project management, leadership, communication
• Proficiency levels: Beginner, intermediate, advanced, expert

Mapping Methods

• Skills matrix: Excel spreadsheet/dedicated tool with skills × people
• Individual interviews: Self-assessment + manager validation
• Technical tests: Practical assessments to validate levels
• Project analysis: Skills actually used vs declared
• Capacity planning tools: Workload enables tracking skills by project

1.2 Identifying Future Needs

To identify gaps, project skill needs at 12-24 months:

• Project roadmap: What skills will be needed for planned projects?
• Technological evolution: What emerging technologies will need to be mastered?
• Business strategy: What new business domains will be addressed?
• Planned departures: What critical skills are at risk of leaving?

Gap Matrix

Create a matrix comparing Current Skills vs Required Skills:

• Critical gap: Skill absent and needed short-term
• Important gap: Skill present but insufficient level
• Moderate gap: Skill to develop for medium-term
• Overcapacity: Skill present but little used (risk of loss)

1.3 Prioritizing Gaps

Prioritize gaps according to two criteria:

• Criticality: Impact on strategic projects (high/medium/low)
• Urgency: Time before need (immediate/3-6 months/6-12 months)

Prioritization Matrix

• Priority 1 (Critical + Urgent): Immediate training/recruitment
• Priority 2 (Critical + Not urgent): Training planning 3-6 months
• Priority 3 (Not critical + Urgent): Temporary outsourcing
• Priority 4 (Not critical + Not urgent): Long-term training

5. ROI of Training vs Recruitment

5.1 Calculating Training ROI

Training ROI is calculated as follows:

Training ROI = ((Gains - Costs) / Costs) × 100

Gains = 
  - Savings on recruitment (costs avoided)
  + Additional productivity
  + Turnover reduction
  + Innovation created

Costs = 
  - Training costs (courses, certifications, time)
  + Opportunity costs (non-productive time)

Calculation Example

Cloud training for 5 developers:

• Costs:
  • Training: 5 × $3,000 = $15,000
  • Training time: 5 × 160h × $50/h = $40,000
  • Total: $55,000
• Gains:
  • Recruitment savings: 1 × $80,000 = $80,000
  • Productivity: +20% × 5 × $50,000/year = $50,000/year
  • Retention: -1 departure × $50,000 = $50,000
  • Total year 1: $180,000
• Year 1 ROI: ((180,000 - 55,000) / 55,000) × 100 = 227%

5.2 Calculating Recruitment ROI

Recruitment ROI is calculated as follows:

Recruitment ROI = ((Gains - Costs) / Costs) × 100

Gains = 
  - Immediate productivity
  + Expertise brought
  + Innovation

Costs = 
  - Annual salary
  - Recruitment costs (15-30% of salary)
  - Integration costs (3-6 months)
  - Turnover risk (30-40%)

Calculation Example

Recruitment of a Cloud expert:

• Costs:
  • Salary: $80,000/year
  • Recruitment: $20,000
  • Integration: 3 months × $6,700 = $20,000
  • Total year 1: $120,000
• Gains:
  • Productivity: $80,000/year
  • Expertise: +30% cloud projects = $30,000/year
  • Total year 1: $110,000
• Year 1 ROI: ((110,000 - 120,000) / 120,000) × 100 = -8% (negative first year)
• Year 2 ROI: ((110,000 - 80,000) / 80,000) × 100 = 38% (positive from year 2)

5.3 Training vs Recruitment Comparison

Our study reveals that:

• Internal training: Average ROI 200-300% over 2 years
