IT Service Management roles and responsibilities

No IT Service Management (ITSM) initiative can ever work without people. In fact, the 4 P’s of ITIL® Service Design include People so that should say something about how important it is to structure and organize the people involved in delivery of IT services. People constitute part of the resources and capabilities required to deliver quality IT services to users and customer alike. And since quality service delivery is all about dealing with customers, users and suppliers, the value of instituting proper roles and responsibilities in IT cannot be understated.

A role is a set of responsibilities, activities and authorities granted to a person or team. A role is defined in a process or function. One person or team may have multiple roles – for example, the roles of incident manager and problem manager may be carried out by a single person. Roles are often confused with job titles but it is important to realize that they are not the same. Each organization will define appropriate job titles and job descriptions which suit their needs, and individuals holding these job titles can perform one or more of the required roles.

Organizational structures

There is no single best way to organize, and best practices described in ITIL® need to be tailored to suit individual organizations and situations. Any changes made will need to take into account resource constraints and the size, nature and needs of the business and customers. The starting point for organizational design is strategy, as it sets the direction and guides the criteria for each step of the design process. For strategy to be successful, an organization will need to clearly define the roles and responsibilities required to undertake the processes and activities.

An organization’s age, size, geographical spread and technology use affect its structure. As the organization grows and matures, changes in roles and relationships must be made or problems will arise. This is particularly important for organizations adopting a service orientation, as pressures for efficiency and discipline inevitably lead to greater formalization and complexity. In a small organization multiple roles may be combined under one person. In larger organizations there may be many different people carrying out each of these roles, split by geography, technology or other criteria.

The differences between small and large IT organization can be seen in the table below:

Small IT Organization Large IT Organization
Roles are combined Roles are separate
Segregation of duties limited Segregation of duties maximized
Generalization of skills Specialization of skills
Less complexity More complexity

Example of a small IT department structure

For a small department, multiple roles can be combined as shown. While the numbers are few, the people can be charged with owning multiple services and processes. This structure is simple in nature.

Example of a large IT department structure

For a large department, specialization can take place as dedicated service and process roles can be assigned to individuals and teams where necessary. Care must be taken to ensure a silo mentality does not arise and also complexity managed due to the various interlinkages between multiple units and persons.

Roles in IT Service Management

In ITSM, roles can be categorized or combined in a number of different ways, depending on the organizational context. There are roles that directly interact with people (front facing) while others deal directly with technology (back end). In addition some seem to be a hybrid of the two based on their specialist nature. There are also roles that are directly related to services and others related to processes.

Clear definitions of accountability and responsibility are essential for effective service management. To help with this task the RACI (Responsible – Accountable – Consulted – Informed) model or "authority matrix" is often used within organizations to define the roles and responsibilities in relation to processes and activities. According to ITIL® Service Strategy 2011 publication (pg. 337), the RACI matrix provides a compact, concise, easy method of tracking who does what in each process and it enables decisions to be made with pace and confidence. When using RACI, there is only one person accountable for an activity for a defined scope of applicability. Hence, there must be only one process owner for each process and one service owner for each service.

R - Responsible The person or people responsible for correct execution – for getting the job done
A - Accountable The person who has ownership of quality and the end result. Only one person can be accountable for each task
C - Consulted The people who are consulted and whose opinions are sought. They have involvement through input of knowledge and information
I - Informed The people who are kept up to date on progress. They receive information about process execution and quality

For the sample roles outlined below, some of them are based on ITIL processes while others are based on common IT practices, and the names and combinations may vary depending on the organization. Key thing for every IT organization is to ensure that based on their structure, service offerings and processes, relevant roles are identified, documented and assigned and constantly reviewed. The specific roles within ITIL service management all require specific skills, attributes and competences from the people involved to enable them to work effectively and efficiently. However, whatever the role, it is imperative that the person carrying out that role has the following attributes:
