The Value of Change Models


In ITSM as in life change is inevitable.  In order for us to continually deliver services that are meaningful and bring value to our customers, we must frequently update and upgrade not only the services we deliver but also the underlying infrastructure, technology and applications that are utilized and managed to deliver these services.  The ITIL definition of a change is “the addition, modification or removal of anything that could have an effect on the delivery of an IT service.
The purpose of the change management process is to control the lifecycle of all changes, allowing us to make beneficial changes with minimal disruption to our current IT services.  The objective is to be able to respond to these changing requirements while safeguarding value and reducing rework.   Additionally ITSM must ensure that services continue to align to overall business strategy and that we have the processes and mechanisms in place to guarantee that all changes and the configuration items (CI) are being recorded and overall business risk is being assessed and optimized. This can be a daunting task in any size organization.
Organizations can utilize predefined change models in helping them to manage this process.  A change model is a technique of predefining the steps and the sequence of those steps, which should be taken to carry out a particular type of change in an agreed manner.  They can be built around the three different types of changes, Standard, Emergency and Normal.
All change models should include the following:
  • Steps to be taken to handle the change, including issues and unexpected events.
  • The chronological order in which the steps are to be taken, with dependences or co-processes defined.
  • Responsibilities – who does what! Accountable and responsible parties should be defined.
  • Timescale and thresholds for each of these action items to be undertaken.
  • Escalation procedures.
  • These models can be integrated into the support tool for automated handling, management and reporting.
The value that can be realized by employing change models will be a greater and more effective ability to protect the business from the negative impact from disruptions and delays, ability to meet governance requirements, the reduction of failed changes, reduction of risk and being able to meet the ever increasing demand for timely and accurate changes.

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 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 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 ...

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.      ...
