To apply ISO/IEC 20000, you need to follow a systematic process that involves defining the scope and objectives of your ITSMS, establishing and implementing your ITSMS, monitoring and reviewing your ITSMS, and improving your ITSMS. When defining the scope and objectives, you should determine which IT services, processes, and functions are covered by your ITSMS, as well as the goals and outcomes you want to achieve. When establishing and implementing your ITSMS, you should design and document IT service management policies, processes, and procedures according to the requirements of ISO/IEC 20000-1. You should also ensure that you have the necessary resources, roles, and responsibilities to support your ITSMS. When monitoring and reviewing your ITSMS, you should collect and analyze data on the performance and quality of your IT services, processes, and functions. You should also conduct audits and assessments to verify that your ITSMS conforms to the standard and meets your objectives. Finally, when improving your ITSMS, you should identify opportunities for improvement based on the results of monitoring and review activities. You should also update and maintain your ITSMS documentation and records.
