What is ITIL in ITSM?

Companies are accustomed to working with resources. For example, a company may have an electrician to fix wiring issues and address problems in the electrical network. In this case, the intended use of the resource is clearly defined – the business knows how much time and resources will be required for the electrician to complete the work. There is little room for surprises or uncertainties.

However, when it comes to using IT infrastructure, the situation becomes less transparent. Why does the restoration of an IT system, such as corporate email, take only 5 minutes in some cases, while in others it requires several days of waiting or acquiring a new server?

This is where ITSM services come into play – processes for managing IT services and providing them to customers at all stages. This approach goes beyond addressing individual user requests and becomes formalized service provision. It is manifested in the creation of a structured service catalog, the development of service level agreements (SLAs), and the systematic provision of services upon request.

ITSM services control all types of technology in the workplace, ranging from laptops and servers to business-critical software applications.

So, what role does ITIL play in technical support? Let’s dig deeper. ITIL, also known as IT Infrastructure Library, is a library of IT infrastructure consisting of a set of recommendations aimed at helping companies maximize the efficient use of IT by aligning IT services with business strategy.

In other words, ITSM is a kind of methodology for delivering IT services to the business, and the ITIL framework is designed to implement ITSM in the business through its practices.

5 stages of ITIL in SDLC

There is an IT product lifecycle designed for successful software deployment in the market. In order to deliver a high-quality product to users, it is necessary to go through all stages of the Software Development Life Cycle (SDLC). Some of these stages are repeated in the ITIL framework but have a broader scope related to managing IT services and infrastructure.

1. Service Strategy

  • In this stage, business and customer requirements are identified and analyzed.
  • Strategic goals and software development plans are defined to support these requirements.

2. Service Design

  • This stage involves designing IT services, including software.
  • Design concepts and architecture are created for the developed software.

3. Service Transition

  • This stage is related to the implementation of the developed software and transitioning from the current state to a new version or service.
  • It includes testing, change management, and deployment of new software.

4. Service Operation

  • At this stage, the developed and implemented software is actively used.
  • Support and management of IT services take place, including incident handling and problem management.

5. Continual Service Improvement

  • This stage involves monitoring, analysis, and continuous improvement of the quality and performance of IT services, including software.
  • Measures are taken to resolve issues and enhance the efficiency of software utilization.
Thus, ITIL service management defines the lifecycle of an IT product. It is important to adapt the ITIL approach in technical support to the business needs and software development tools.

Practices of ITIL support

Earlier, we understood that the ITIL framework implements the principles described in ITSM through practices. The concept of “practices” is broader than “processes” in SDLC and takes into account factors such as personnel, their key competencies, technologies, etc.

Here are some of the key ITIL service management practices in technical support:

1. Incident Management

  • A practice focused on detecting, registering, classifying, and restoring incidents affecting the functioning of IT services.
  • It includes managing incident priorities, communicating with users, and aligning with service level agreements.

2. Problem Management

  • A practice aimed at identifying and eliminating the root causes of recurring incidents or significant issues in the IT infrastructure.
  • It involves problem analysis, creating action plans to prevent future incidents, and improving service quality.

3. Change Management

  • A practice related to planning, controlling, and monitoring changes in IT services and infrastructure.
  • It includes processes for evaluating changes, implementing them, and managing associated risks and disruptions.

4. Release Management

  • A practice focused on planning, coordinating, and managing the release of new software versions or updates in the IT infrastructure.
  • It includes version control, testing, deployment, and change management processes within releases.

5. Service Level Management

  • A practice related to establishing, negotiating, and monitoring service levels according to user and business requirements.
  • It involves defining service levels, agreeing on service level agreements (SLAs), measuring and reporting on achieved service levels.

6. Configuration Management

  • A practice aimed at maintaining and managing the configuration and status of all IT infrastructure components and related services.
  • It includes processes and methods for identification, control, recording, and analysis of configurations to ensure system integrity and availability.

7. IT Service Continuity Management

  • A practice related to planning and ensuring the continuous functioning of IT services in the event of catastrophic events or emergencies.
  • It involves creating recovery plans, data backups, and testing systems in emergency situations.

8. Service Desk

  • A practice related to providing a user contact center for incident registration, requests, and customer service.
  • It includes processes for initial support, request management, and timely and quality resolution of user issues.
Applying ITIL service management practices in technical support enables more structured and efficient management of incidents, problems, and changes in software, as well as improving user service quality.

Through these practices, companies introduce standardization, automation, and optimization in software technical support processes, leading to increased user satisfaction and software stability.

Benefits of ITIL management in IT

🔴 Service Transparency

ITIL support provides a structured way of documenting and presenting IT services to customers, users, and stakeholders. This transparency allows them to understand the available services and their current status.

🔴 Lifecycle Management

ITIL support covers the entire lifecycle of IT services, from initial concept to development, deployment, and retirement. This comprehensive approach ensures structured service management from start to finish.

🔴 Risk Management

ITIL support helps organizations understand the service ecosystem, including any dependencies, enabling them to identify weaknesses, plan for potential failures, and develop appropriate action plans for unforeseen circumstances.

🔴 Customer-Centric Approach

ITIL support focuses on meeting the needs of customers and stakeholders, aligning services accordingly. This customer-centric approach enhances outcomes, experiences, and customer satisfaction levels.

What companies gain from ITIL service management:

⚪️ Unified system

By implementing ITIL service management, companies have a centralized repository where all registered IT incidents are stored. Each incident is carefully documented and accessible in a single repository, which the support team can utilize to swiftly resolve issues.

⚪️ Time and resource savings

IT incidents are automatically classified based on various parameters such as priority, urgency, impact, and the relevant department. This enables the IT team to focus solely on resolving the problem, bypassing the stages of troubleshooting and assigning priority.

⚪️ Guarantee and reliability

IT incident requests are matched with corresponding Service Level Agreements (SLAs) to ensure compliance with requirements. For example, a company has a signed SLA agreement with an outsourcing agency. New incidents are automatically included in the agreement, providing a guarantee for issue resolution.

⚪️ Improved responsiveness

Automatic assignment of technical specialist or support group for further investigation and consideration of the incident. For instance, a delay in addressing a software bug led to a decline in a company’s profit. With the ITIL system, incidents are promptly categorized by level and priority, then assigned to the appropriate specialists for quick resolution.

⚪️ Priority setting

Determining optimal solutions or temporary fixes for each incident. ITIL helps guide technical specialists on the decisions to be made to rectify software errors and failures while mitigating negative consequences.

⚪️ Leveraging past incident resolutions

Solutions are documented in a knowledge base, allowing for future utilization.

⚪️ Analytics

Creation of interactive dashboards and reports based on support data for incident resolution analysis. This enables companies to assess the current situation and evaluate the performance of technical specialists.
