Should everything be kept in-house for control? Should everything be outsourced to reduce costs? Or should a hybrid model be adopted? This strategic study, conducted in 2026, analyzes practices from over 200 French IT departments to identify roles to outsource, those to keep in-house, decision criteria, hybrid models, and best practices for optimizing the outsourcing/internalization mix. ## 1. Understanding Outsourcing vs Internalization ### 1.1 Definition of Internalization **Internalization** consists of keeping IT resources in-house, with salaried teams from the organization. Advantages: - ✅ **Total control**: Direct control over teams and Processes - ✅ **Business knowledge**: Integrated teams, understanding of context - ✅ **Reactivity**: Quick decisions, no contractual delays - ✅ **Capitalization**: Accumulated knowledge, continuity - ✅ **Confidentiality**: Internal data and Processes Disadvantages: - ❌ **High fixed costs**: Salaries, charges, premises - ❌ **Rigidity**: Difficulty adjusting quickly - ❌ **Limited skills**: Dependence on internal skills - ❌ **HR management**: Recruitment, training, turnover ### 1.2 Definition of Outsourcing **Outsourcing** consists of entrusting all or part of IT activities to an external provider. Advantages: - ✅ **Cost reduction**: 20-40% savings on average - ✅ **Flexibility**: Quick volume adjustment - ✅ **Expertise**: Access to specialized skills - ✅ **Focus**: Concentration on core business - ✅ **Innovation**: Access to latest Technologies Disadvantages: - ❌ **Loss of control**: Dependence on provider - ❌ **Quality risks**: If provider not performing - ❌ **Hidden costs**: Management, coordination, transition - ❌ **Business knowledge**: Less good understanding of context - ❌ **Security risks**: External data ### 1.3 Hybrid Models: Co-sourcing **Co-sourcing** combines internalization and outsourcing to benefit from advantages of both: - **Model 1: By activity**: Some activities in-house, others outsourced - **Model 2: By skill**: Critical skills in-house, others outsourced - **Model 3: By project**: Strategic projects in-house, others outsourced - **Model 4: By level**: L1/L2 outsourced, L3 in-house **65% of IT departments** adopt a hybrid model, which offers the best cost/quality/control balance. ## 2. Which Roles to Outsource? ### 2.1 Roles to Outsource as Priority Based on our analysis, here are the roles most often successfully outsourced: #### L1/L2 Support (85% of IT departments) - **Why**: Repetitive, standardizable, non-differentiating activities - **Savings**: 30-40% cost reduction - **Quality**: Often better (specialization, SLA) - **Models**: Externalized service desk, service centers - **Risks**: Low if SLA well defined #### Legacy Maintenance (70% of IT departments) - **Why**: Old systems, rare skills, low strategic value - **Savings**: 25-35% cost reduction - **Quality**: Equivalent or better (legacy specialists) - **Models**: Application maintenance, legacy technical support - **Risks**: Medium (dependence, business knowledge) #### Infrastructure Operations (60% of IT departments) - **Why**: Monitoring, backups, server management, standardizable - **Savings**: 20-30% cost reduction - **Quality**: Often better (24/7, specialization) - **Models**: Cloud managed services, externalized NOC - **Risks**: Low if cloud/SLA well managed #### Non-Strategic Development (50% of IT departments) - **Why**: Low strategic value projects, standardizable - **Savings**: 30-50% cost reduction - **Quality**: Variable depending on provider - **Models**: Offshore development, nearshore - **Risks**: Medium to high (quality, communication) ### 2.2 Roles to Keep In-House Based on our analysis, here are the roles to keep in-house: #### IT Architecture (95% of IT departments) - **Why**: Strategic, differentiating, requires business knowledge - **Outsourcing risks**: Loss of strategic Vision, dependence - **Recommendation**: Keep in-house, possibly occasional assistance #### IT Security (90% of IT departments) - **Why**: Critical, confidentiality, regulatory compliance - **Outsourcing risks**: Data security, compliance - **Recommendation**: Keep in-house, possibly external audits #### Innovation and R&D (85% of IT departments) - **Why**: Differentiating, strategic, requires agility - **Outsourcing risks**: Loss of competitive advantage - **Recommendation**: Keep in-house, possibly external POCs #### Strategic Development (80% of IT departments) - **Why**: Core business applications, differentiating - **Outsourcing risks**: Loss of control, quality - **Recommendation**: Keep in-house, possibly occasional reinforcement #### IT Project Management (75% of IT departments) - **Why**: Requires business knowledge, internal coordination - **Outsourcing risks**: Loss of control, communication - **Recommendation**: Keep in-house, possibly methodological assistance ## 3. Decision Criteria: Outsourcing vs Internalization ### 3.1 Criterion 1: Strategic Value **Rule**: The more strategic/differentiating the activity, the more it should stay in-house. - **Strategic**: Keep in-house (architecture, security, innovation) - **Operational**: Can be outsourced (L1/L2 support, legacy maintenance) - **Standardized**: To outsource (infrastructure operations, repetitive tasks) ### 3.2 Criterion 2: Available Skills **Rule**: If skills are rare/expensive in-house, consider outsourcing. - **Common skills**: Easy to recruit → Keep in-house - **Specialized skills**: Difficult to recruit → Outsourcing or co-sourcing - **Legacy skills**: Very rare → Outsourcing recommended ### 3.3 Criterion 3: Costs **Rule**: Calculate TCO (Total Cost of Ownership) to compare. - **Internal costs**: Salary + charges (50%) + premises + training + turnover + management - **Outsourcing costs**: Services + management (15-20%) + coordination + transition - **Expected savings**: 20-40% on average if well managed ### 3.4 Criterion 4: Risks **Rule**: Assess operational, security, compliance risks. - **Low risks**: L1/L2 support, standardized operations → Outsourcing OK - **Medium risks**: Non-strategic development → Co-sourcing recommended - **High risks**: Security, sensitive data → Keep in-house ### 3.5 Criterion 5: Agility and Flexibility **Rule**: If high reactivity needed, favor in-house. - **Critical reactivity**: Keep in-house (critical support, incidents) - **Variable volumes**: Outsourcing for flexibility - **Occasional projects**: Outsourcing or co-sourcing ## 4. Outsourcing Models ### 4.1 Onshore (France) - **Advantages**: Same time zone, close culture, high quality - **Disadvantages**: Higher costs (20-30% more than offshore) - **Usage**: Critical support, strategic projects - **Costs**: $50-80/h on average ### 4.2 Nearshore (Eastern Europe, Portugal) - **Advantages**: Close time zone, reduced costs, good quality - **Disadvantages**: Slight cultural differences - **Usage**: Development, L2 support - **Costs**: $30-50/h on average ### 4.3 Offshore (India, Asia) - **Advantages**: Very reduced costs (50-70% savings), large capacities - **Disadvantages**: Different time zone, cultural differences - **Usage**: Non-strategic development, maintenance - **Costs**: $15-30/h on average ### 4.4 Cloud Managed Services - **Advantages**: Scalability, cloud expertise, optimized costs - **Disadvantages**: Dependence on cloud provider - **Usage**: Cloud infrastructure, SaaS - **Costs**: Pay-as-you-go, often 30-40% savings ## 5. ROI Calculation: Outsourcing vs Internalization ### 5.1 Internal Costs (TCO) To Calculate real cost of an internal resource: Internal cost = Gross salary + Charges (50%) + Premises + Training + Turnover + Management Example: $60k/year × 1.5 (charges) + $5k (premises) + $3k (training) + $10k (turnover) = $108k/year ### 5.2 Outsourcing Costs To Calculate real cost of outsourcing: Outsourcing cost = Services + Management (15-20%) + Coordination + Transition + Risks Example: $70k/year (services) + $14k (management) + $5k (coordination) = $89k/year ### 5.3 ROI Calculation ROI = (Savings - Transition costs) / Transition costs × 100 **Example**: - Internal cost: $108k/year - Outsourcing cost: $89k/year - Savings: $19k/year (18%) - Transition costs: $15k (one-time) - ROI year 1: ($19k - $15k) / $15k × 100 = **27%** - ROI year 2+: $19k / $15k × 100 = **127%** ## 6. Use Cases: Outsourcing Optimization ### Case 1: IT Department 100 people - Outsourcing L1/L2 Support **Context**: Overloaded internal support, high costs **Actions**: - Outsource L1/L2 support (15 people → provider) - Keep L3 support in-house (5 people) - SLA: 95% L1 resolution, 70% - ✅ **Reporting**: Real-time dashboards - ✅ **Penalties**: If SLA not met ### 7.3 Manage Transition - ✅ **Transition plan**: 3-6 months progressive - ✅ **Knowledge transfer**: Documentation, training - ✅ **Steering**: Dedicated transition team - ✅ **Tests**: Validation before full switch ### 7.4 Monitor and Optimize - ✅ **Regular KPIs**: Monthly minimum - ✅ **Performance reviews**: Quarterly - ✅ **continuous feedback**: continuous improvement - ✅ **Renegotiation**: If volumes/quality evolve ## 8. FAQ - Outsourcing vs Internalization ### Which IT roles should be outsourced as priority? Roles to outsource as priority are: L1/L2 support (85% of IT departments), legacy maintenance (70%), infrastructure operations (60%), and non-strategic development (50%). These activities are standardizable, non-differentiating, and enable 20-40% savings. ### Which IT roles should be kept in-house? Roles to keep in-house are: IT architecture (95% of IT departments), security (90%), innovation/R&D (85%), strategic development (80%), and project management (75%). These activities are strategic, differentiating, and require Deep business knowledge. ### What is the average ROI of IT outsourcing? The average ROI of IT outsourcing is 200-300% over 2-3 years. Direct savings are 20-40% on average, but transition costs (10-20% of annual cost) and management costs (15-20% of services) must be taken into account. ### What is co-sourcing and when to use it? Co-sourcing combines internalization and outsourcing to benefit from advantages of both. It is recommended for medium-value activities, projects with variable volumes, or when wanting to maintain control while benefiting from flexibility. 65% of IT departments adopt a hybrid model. ### How to Calculate TCO (Total Cost of Ownership) of an internal resource? TCO of an internal resource = Gross salary + Social charges (50%) + Premises + Training + Turnover + Management. Example: $60k/year × 1.5 (charges) + $5k (premises) + $3k (training) + $10k (turnover) = $108k/year. This is the cost to compare with outsourcing. ### What are outsourcing risks and how to mitigate them? Main risks are: loss of control, variable quality, hidden costs, dependence, security. To mitigate: choose the right provider, define clear SLAs, actively manage the relationship, keep an internal steering team, and plan exit clauses. ## 9.
