Cons:
- Can lead to silos if communication between teams is not managed well
5. Matrix structure
The matrix structure combines functional and divisional approaches, allowing team members to report to multiple managers based on projects or functions. This can promote collaboration but may also create complexity in reporting.
Pros:
- Flexibility in resource allocation across projects
- Encourages teamwork among diverse skill sets
Cons:
- Potential confusion in reporting lines
- Can be challenging to manage effectively
What is ITOM? IT Operations Management Definition, Benefits, And Best Practices
Internal IT departments vs. alternative IT management models
Organizations have several options for managing their IT operations beyond just maintaining an internal IT department. While an internal IT team provides the advantage of dedicated resources that are fully integrated into the company culture and processes, many businesses are increasingly exploring alternative models such as outsourcing, managed services, and hybrid approaches.
Each option offers unique benefits and challenges, allowing companies to tailor their IT strategies to meet specific needs and objectives. Let's explore the differences between these various IT management models, helping you understand how they can complement or enhance your organization’s technology capabilities.
Internal IT
An internal IT team operates fully within the company, handling day-to-day support, network administration, cybersecurity, and more. The key advantages are complete control over the systems, direct alignment with the organization’s culture, and the ability to quickly address problems. Additionally, internal teams typically have a deeper understanding of internal processes and long-term goals. However, this model requires significant investment in employee salaries, ongoing training, and infrastructure.
Pros:
- Full control over IT operations
- Immediate response to issues
- Deep knowledge of company-specific needs
Cons:
- High costs related to salaries, training, and equipment
- Limited flexibility to scale without major investments
Outsourcing
Outsourcing shifts IT responsibilities to third-party providers. This can range from basic services like help desk support to more advanced functions such as cybersecurity or network management. Outsourcing IT can lower operational costs by reducing the need for internal hires and hardware investments. However, companies may face challenges in responsiveness and the ability to customize solutions according to unique needs.
Pros:
- Lower costs for staffing and infrastructure
- Access to external expertise
- Flexibility in scaling services up or down
Cons:
- Potential delays in support response
- Less control over IT operations

Managed services
Managed services take outsourcing a step further by providing ongoing, proactive IT support through subscription-based contracts. These services often cover essential IT functions like monitoring, data backup, and security. Managed service providers focus on preventing issues before they arise, giving businesses the ability to scale operations as needed without the burden of managing systems themselves.
Pros:
- Predictable monthly costs
- Proactive monitoring and maintenance
- Scalable services as business needs evolve
Cons:
- May not offer deep customization
- Dependence on third-party for critical services
Hybrid IT models
Hybrid IT models combine internal IT teams with external service providers. This allows companies to retain control over key systems while outsourcing non-core functions, like cloud services or technical support. Hybrid models provide flexibility, allowing businesses to optimize their IT strategy based on specific needs and budgets.
Pros:
- Flexibility to keep key operations in-house
- Ability to scale services externally when needed
- Control over critical systems with external support for specialized tasks
Cons:
- Managing multiple vendors can be complex
- Balancing in-house and external teams requires coordination

IT consulting: complementing IT departments
While consulting isn't a long-term IT department model, it plays an important role in supporting businesses during specific projects. IT consultants bring specialized knowledge and experience that internal teams might lack, particularly in areas like digital transformation, software implementation, or cloud migration. Unlike ongoing IT department models, consulting engagements are short-term and focused on helping businesses execute high-impact initiatives or make strategic decisions.
IT consulting typically works alongside internal teams, providing guidance and expertise for complex, project-specific tasks. For example, consultants might advise on the best infrastructure for a company’s growth or assist with integrating new technologies. After the project is complete, internal IT or external providers usually take over ongoing management.
Pros:
- Access to specialized expertise for complex projects
- Focused, short-term engagements without long-term commitments
- External perspective to support strategic decision-making
Cons:
- Can be expensive, particularly for large-scale projects
- Limited to advisory roles; doesn’t replace the need for daily IT operations
The role of IT governance
Regardless of which IT management approach a business adopts, effective IT governance ensures that all technology investments align with organizational goals. Governance provides the structure for decision-making, risk management, and accountability, which is crucial for managing technology efficiently, especially in complex environments with multiple providers or hybrid models.
Frameworks like COBIT, ITIL, and ISO/IEC 27001 are designed to help companies manage risks and maintain compliance. However, governance can look different depending on the IT model. For internal teams, governance may involve stricter controls and direct oversight, while for hybrid or outsourced models, it focuses on managing external vendors and ensuring that services meet performance standards.
In hybrid models, governance also helps ensure that internal and external teams collaborate effectively. For example, companies need clear policies on dividing responsibilities, such as who handles data protection or system recovery in case of a disruption.
Another consideration for businesses is the rise of shadow IT, which refers to employees using unauthorized software or tools without the approval of the IT department. Shadow IT can create significant security risks, especially in weak governance environments or where the IT department is stretched thin. In hybrid and outsourced models, managing shadow IT becomes even more difficult, as external providers may not have full visibility into internal practices.
