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.  E...

The best practice approach and the Seven-step Improvement Process for Continual Service Improvement (CSI) begin with identifying the vision, mission, goals and objectives of the business.  In order to measure with appropriate targets these outcomes and objectives must be quantified. If you cannot measure it you cannot improve it.  First and foremost in order to perform ongoing CSI for a service we must identify the service.  That is just common sense right?  Yet how many discussions take place in Sales, in Development, and in Operations about whether something is or is not a service.  Collectively everyone in the lifecycle has a mission to meet the outcomes of the service or services that are being provided.  Measuring and Reporting For CSI to be successful we measure and monitor and report upon a service end-to-end.   When measuring and reporting IT managers will generally report availability in terms of percent with such things as ...

I was recently asked to comment on the importance of Demand Management for IT Services as it relates to the IT Business organization. Demand Management Demand Management is tied to the “Customer” or consumer demand. It is more about the market and what is the demand from that level. Strategic Example Strategic Demand Management might be a business strategy for how to influence user behavior. The telecom industry a few years back offered “Free nights and weekends”. This was a “Strategy” to manage the “Demand” until the provider could get all of the infrastructure laid down to support the demand for service. Tactical Example Within the activities of “Demand Management “ are those that are defined to monitor, manage, and report upon the patterns of business activities (PBA) and the activities of the varied user profiles (UP’s) . Demand Management would provide the UP’s and PBA’s and work very closely with Capacity management (managing workload at the component level to meet ...

This article was originally published in 2015. With the Introduction of ITIL 4, some of the concepts have changed in ways that are described below. ITIL 4 has also introduced new roles, as explained in our blog ITIL 4 and the Evolving Role of Roles . Before we dive into the difference between these roles, let’s first look at a key update in ITIL 4 – the shift from processes to practices. ITIL 4 has evolved to focus on holistic practices vs. isolated processes. By definition, a practice is a set of organizational resources designed for performing work or accomplishing an objective. For example, the purpose of the incident management practice is to minimize the negative impact of incidents by restoring normal service operation as quickly as possible. All organizations recognize the need to allocate resources to the management of incidents and mature their capabilities in that area. In ITIL 4, each practice includes resources based on the four ...
