ISO 20000 family of IT service safety management standards

What is the value of ISO 20000? Answer first, what is the value of your IT systems? Your IT systems are intrinsic to your success. The nervous system pulsing through your organization, IT systems affect how you operate and communicate. Emerging technologies are assuming decision making and defining operational goals, effectively becoming the mind of the organization. 
For most organizations, IT is in equal parts a competitive advantage and the Achilles’ heel. Therefore, it’s vital that your IT investments and services are well-planned, designed, managed and delivered. Without IT service management, IT projects go over budget and more often than not miss the mark entirely in customer service and productivity. Operational costs become unmanageable and entire businesses are at risk of failure with IT mismanagement.
ISO 20000 is designed for any organization of any size in any sector, which engages information technology. ISO consists of eight interdependent parts, two of which are more commonly used ISO 20000-2:2011 and ISO 20000-2:2012.
 ISO 20000-1:2011 defines the requirements you need to deliver IT services to meet your customers’ expectations. It includes:

Service Management System requirements
Design and transition of new or changed services
Service delivery processes
Relationship processes
Resolution processes
Control processes

ISO 20000-2:2012 is the code of practice for IT service management. It guides the implementation of service management systems. It interprets the requirements of the standard and defines the best practice management processes.
The value of ISO 20000 can be found in 
Your image and credibility – ISO 20000 is the only internationally recognized standard for IT service management. Achieving ISO 20000 certification is an indication to your customers, suppliers and other stakeholders that your IT practices are held against the highest standards in the world.
