What are the functional differences between ITIL V2 and ITIL V3 10

a) Introduce the life cycle.

ITIL V3 introduces the concept of "life cycle". That is, the entire process of IT services from the beginning to the end, including activities such as decision-making, planning, design, development, testing, release, operation, and improvement. With the help of the "life cycle", ITIL V3 organically integrates the various processes in V2, and through the PDCA (Plan, Do, Check, and Action) model, it can be continuously improved in a cyclical manner, so as to keep ITIL alive.

And in ITIL v2. At its core, there is only service support and service delivery, and the modules are relatively isolated from each other and do not have much connection.

b) Increase implementation guidance.

With the introduction of many industry cases, implementation methodologies for small and medium-sized enterprises, and interfaces with other industry standards (e.g., IT governance control frameworks, PMP project management methodology), users can easily implement IT service management in the enterprise.

ITILV2 focuses on implementation and process, while V3 elevates ITIL to the level of enterprise business strategy and biases management. At present, most of the domestic implementation is based on V2. You can go to the ITIL Pioneer Forum to find out more information.

Asda is the name of the legendary Danjun capital of North Korea, also referring to the British Asda company, founded in 1949 and acquired by Walmart in 1999, it was the first supermarket in the United Kingdom to ban the use of artificial colors and flavors in its own food and soft drinks, committed to the production of "pollution-free" food, and is one of the giants of the British retail industry.

Service management is a complete set of organizational capabilities provided to customers in the form of services. This organizational capability is in the form of functions and processes throughout the whole life cycle of strategy, design, transformation, operation and continuous improvement, reflecting the organization's ability and confidence in action, and the action of converting resources into valuable services is the core of service management. Without this organizational operational capacity, the service organization can only provide the relatively low value inherent in the customer's resources.

What is a service?

Service is a method that brings value to customers by providing them with the results they want to achieve conveniently without bearing special costs and risks.

In the definition of service in ITIL V3, two meanings are expressed: the "outcome" that the customer wants and the "special cost and risk" that the customer does not want, and the combination of the two reflects the value that the service brings to the customer. A function is an organizational unit that specializes in performing a certain type of work and is accountable for the specific results produced.

Functions define roles and associated delegation of authority and are accountable for clear performance and results. Functions can have their own knowledge through the accumulation of experience, forming a stable organizational structure. Coordination between functions needs to be achieved through processes.

The process model helps to improve cross-functional coordination and control, thus avoiding functional-level issues. Well-designed processes can lead to increased productivity within and between functions. The structure of the ITIL service lifecycle includes:

Problem Identification, Evidence Collection, Experimentation and Documentation Service Strategy, Design, Transition, Operations & Continuous Improvement **Collect, Procure, Configure, Monitor & Replace Service Address, Follow-up, Corrective Action, Monitoring & Continuous Improvement.

ITIL (IT Infrastructure Library) was originally developed by the British Computer and Telecommunications Bureau (CCTA) (now merged into the British Business Office OGC) in the 80s of the 20th century a set of IT service management standard library, it is a best practice framework for IT service management, and has now become the de facto standard in the field of international IT service management. ITIL emphasizes the IT management concept based on "customer-centric and process-oriented", reorganizes the traditional IT management activities according to the way of process, and emphasizes the provision of reliable quality and reasonable cost IT services according to the business needs of customers.

Hello In the late 80s of the 20th century, the British Department of Commerce (OGC, Office Government Commerce) released ITIL. The initial goal of the OGC was to improve the efficiency of the business through the application of IT; The goal is to be able to minimize the lack of communication between the different IT functions. OGC recognizes the need to manage different IT components such as hardware, software, and computer-based communications to improve the effectiveness and efficiency of the IT program, which will ensure optimal IT usage.

OGC enlisted help from IT management industry experts and began documenting their experiences.

Initially a best practice guide for the IT sector, ITIL was soon introduced to the private sector in the UK, then across Europe, and then in the US. Since 1980 to the present, ITIL has gone through three main editions:

Version 1 — 1986 The original 1999 edition, based primarily on functional practices, developed more than 40 volumes. Version 2—1999 2006 ITIL V2 is based on process-based practices and consists of 10 books with 7 systems: Service Support, Service Delivery, Implementation Service Management Planning, Application Management, Security Management, Infrastructure Management, and ITIL Business Landscape.

It has become a globally recognized framework for best practice in IT service management.

Version 3 — 2004 2007 ITIL v3 based on the service lifecycle combines the best of V1 and V2 and incorporates current best practices in IT service management. The 5 Lifecycle Books form the core of ITIL V3, which focuses on supporting the implementation of ITIL best practices and the details that need to be paid attention to in the process of improvement.

So this is not a panacea, it's just a guide.
