Self-service is a support model that allows end users to solve their own problems or fulfill their own service requests without the need for direct assistance from a support agent. Self-service solutions are typically provided via a web-based portal or mobile application and allow users to access a range of resources and tools to help them resolve their own issues. 

Common examples of self-service solutions include: 

• Knowledge base articles: End users can access a library of articles and resources to help them troubleshoot or provide answers to frequently asked questions. 
• Chatbots: Chatbots can provide automated assistance to end users through natural language processing and machine learning, helping them resolve issues or fulfill service requests without the need for human intervention. 
• Self-service portals: These provide users with a set of tools and resources, including the ability to log and track their own incidents or service requests, view status updates, and access a range of self-help resources. 
• Video tutorials: Users can access video tutorials and other multimedia resources to learn how to use software applications, devices, or other technologies. 

Self-service solutions offer organizations a number of benefits, including greater efficiency, lower costs, and higher end-user satisfaction. By giving users the tools and resources they need to resolve their own issues, organizations can free up their support staff to focus on more complex issues. At the same time, the availability of faster and more convenient support options improves end-user satisfaction. 

In the IT and facility environment, requirements and solutions are constantly changing. Regular training ensures that service desk employees have up-to-date knowledge and are able to provide the best possible support - whether in the IT or facility sector. The training measures are complemented by the integration of knowledge management into day-to-day work.

Feedback tools enable service desks to learn directly from users. This provides valuable insight into areas that require improvement and encourages continuous improvement initiatives. This can be crucial for both IT and facility support measures.

Service desk outsourcing can offer cost savings, as well as access to specialized expertise and better scalability. In particular, it can allow companies to focus on their core competencies while external experts take care of IT and facility support issues. This can also lead to improved service concepts and higher IT service quality.

Service transition is a phase in the IT service management (ITSM) lifecycle that focuses on transitioning new or changed services into the live environment. It comprises the planning, coordination, and implementation of changes to the infrastructure and related services to ensure that the new or changed services are provided to the organization in a controlled and coordinated manner.

Service transition encompasses several key processes, including change management, asset management, and knowledge management. The service transition phase plays a critical role in the overall ITSM lifecycle. By following a structured service transition process, organizations can minimize the risk of disruption to existing services while ensuring that new services are delivered on time and within budget.
