Is ITIL Best Practice or Good Practice?

By definition, ITIL is a set of best practices (refer to glossary and section 1.2.3 of any of the books) It is also considered a "source" of good practice. While this may be confusing, it is important to understand the distinction.

There are many sources of good practice but not all of those sources are validated as "best" practice. While the term is loosely used, best practices should be repeatedly proven to demonstrate tangible value in actual organizations. In fact, today's documented best practice could be tomorrow's good or common practice. That's how service management evolves, improves and becomes institutionalized. Building a service management program can also involve other sources of good practice (i.e., other frameworks, standards, and proprietary knowledge).

ITIL makes it clear that it's best-practice guidelines are not intended to be prescriptive. Each organization is unique and must 'adapt and adopt' the guidance. This will involve taking into account the organization's size, skills/resources, culture, funding, priorities and existing ITSM maturity. The guidance can then be modified as appropriate to suit the organization's needs. I do not know of an organization that has adopted "pure" ITIL best practices. The end result will be a set of practices that are "good" for the organization given its level of maturity.

Four Service Characteristics

Recently I came across several articles by researchers and experts that laid out definitions and characteristics of services. ITIL provides us with a definition that can help drive the creation of value-laden services: A means of delivering value to customers by facilitating outcomes customers want to achieve without the ownership of specific costs and risks. An area that ITIL is not so clear is in terms of service characteristics. Several researchers and experts put forth that services have four basic characteristics (IHIP): Intangibility—Services are the results of actions not things. They have no physical presence and represent a logical set of elements. One way to think of service is “work done for others.” Heterogeneity—Also known as “variability”; services are unique items because of the mechanisms used to deliver services, which is people. Because the people element adds variability, the service is variable. This holds true, especially for the value proposition—not eve...

What Is A Service Offering?

The ITIL 4 Best Practice Guidance defines a “Service Offering” as a description of one or more services designed to address the needs of a target customer or group. As a service provider, we can’t stop there! We must know what the contracts of our service offering are and be able to put them into context as required by the customer. Let’s explore the three elements that comprise a Service Offering. A “Service Offering” may include: Goods, Access to Resources, and Service Actions 1. Goods – When we think of “Goods” within a service offering these are the items where ownership is transferred to the consumer and the consumer takes responsibility for the future use of these goods. Example of goods that are being provided in the offering – If this is a hotel service then toiletries or chocolates are yours to take with you. You the consumer own these and they are yours to take with you. ...

What is the difference between Process Owner, Process Manager and Process Practitioner?

This article was originally published in 2015. With the Introduction of ITIL 4, some of this best practice has changed. See ITIL 4 and the Evolving Role of Roles . Updated Definitions in ITIL 4: Process Owner: In ITIL 4, the concept of 'processes' has expanded into broader 'practices.' Consequently, the Process Owner is now often referred to as the 'Practice Owner.'
