Service Transition: Release Unit vs Release Package

A “Release Unit” describes the portion of a service or IT infrastructure that is normally released as a single entity according to the organizations release policy. The Release Unit can be thought of as a collection of infrastructure items that when packaged together could perform a useful function. The unit may vary depending on the type or item of service asset or service component. The actual components to be released on a specific occasion may include one or more release units, or may include only part of a release unit. Release Units should contain information about the service, its utilities and warranties and release documentation. These components can be grouped together into a Release Package for a specific release. In general the aim is to decide the most appropriate release unit level for each service asset or component.

A “Release Package” is a set of configuration items that will be built, tested and deployed together as a single release. Each release will take the documented Release Units into account when designing the contents of the Release Package. It may sometimes be necessary to create a Release Package that contains only part of one or more Release Units, but this would only happen in exceptional circumstances. Often there will be different ways of designing Release Packages. Consideration should be given to establishing the most appropriate method for identifiable circumstances, stakeholders and possibilities. Where possible, Release Packages should be designed so that some Release Units can be removed if they cause issues in testing. Releases should be uniquely identified according to a scheme defined in the release policy of your organization.

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.' This individual is accountable for the overall design, performance, integration, and improvement of a specific practice within the organization. They ensure that the practice achieves its intended outcomes and aligns with the organization's objectives. Process Manager: Now commonly known as the 'Practice Manager' in ITIL 4, this role is responsible for the day-to-day management of the practice. The Practice Manager ensures that activities are carried out as intended, manages resources assigned to the practice, and oversees the practitioners performing the work. Process Practit...
