3 OBJECTIVES
The role of Change Management is to ensure that all changes are recorded and then evaluated,
authorised, prioritised, planned, tested, communicated, implemented, documented and reviewed
in a controlled manner. Implementing change allows the organisation to weigh the risks of not
implementing the process properly at the planning stages.
The Change Managers are also responsible for standardising the methods and procedures for
efficient and prompt handling of all changes recorded in the standard ITSM tool. The goal is to
respond to the customers changing business requirements while maximising value and reducing
incidents, disruption and re-work.
A change is an event that is:
 approved by management
 implemented with a minimised and accepted risk to existing IT infrastructure or operation
 results in a new status of one or more configuration items (CIs)
 provides increased value to the business (Increased Revenue, Avoided Cost, or Improved
Service) from the use of the new or enhanced IT systems.

4 POLICIES
This section outlines the policies which must be enforced as part of the operation of the process.
Example: The following Change Management policies must be enforced across IS and its suppliers:











WBA Group IT policy
All Changes to Development, test or Production environment shall be recorded
Supporting documentation should be available
Procedures shall be adopted to identify, minimise or avoid the impact of Changes. They
shall define the recording, classification,assessment, updating and closure of all
Changes

Including impact on dependencies assessment
Coding practices will be adopted and adhered to - Evidenced
Changes required to correct the underlying root-cause of problems will be implemented
through the change management process
Change completion shall be monitored, reviewed and reported for effectiveness

Including all change records being closed within 30 days of planned end date
Some specifics for Common Infrastructure (CINF) are embedded in the appendix

9 PROCESS ACTIVITIES
This covers each of the activities /steps that are in scope for the process and which deliver the end-toend process.
The process flow has been streamlined to include only the most important activities and can be seen

9.2

Relation with Incident and Problem Management

As shown on the Change Process Overview (Section 6), there are inputs into Change from both
Incident and Problem. The only output from Incident into Change will be where an Incident
resolution requires an Emergency Change to be raised, for example a bug fix to an application in
production. The output from Problem Management is more frequent, as many Problems will require
a Change to be made to resolve the cause of the Problem.

9.3

Selection Criteria

A change request is a formal communication seeking an alteration to one or more configuration
items. This could take several forms, e.g. Request for Change document, service desk call or a
project request. Different types of change may require different types of change request, not all
require the same levels of bureaucracy.
For expediency as much use as possible should be made of devolved authorisation, both through
the standard change procedure and through the authorisation of minor changes by Change
Management.

Change Management Process – USM-CHG-D01

IT Shared Services
9.4

Ownership of a Change Request

Change requests raised will be reviewed by Change Management to ensure that the tickets are
necessary, fit the selection criteria, and are of correct quality. All requests for change must be raised
in the ITSM tool and in-line with WBA IT policy, regardless of whether the raiser has logged the
change in a separate system.
Once a change request has been raised it will be assigned to the change raiser\owner who will be
responsible for progression of the request through the change process. It is up to the raiser\owner to
assign change tasks where appropriate and to engage the relevant technical teams linked to the
request into the change approval process. The change request will remain with the raiser\owner until
the point of closure.
The majority of change requests will be raised and owned by technical team members and some by
Project managers.
On closing a change request, the owner will assign the correct closure categories that describe the
correct outcome of the change request. This forms a part of the general Change management KPI’s.

9.5

Change Classifications

The classification is determined based on the impact and risk on the organisation and the effort
required to implement the change. The range of possibilities includes everything from changes
which barely require the involvement of IT personnel and which hardly affect the quality of service,
through to changes requiring a lot of resources and the direct approval of top management.
The classification of a change will be driven by two factors:
 Impact – Number of Users / Stores / Sites affected
 Risk – Configuration Item

IT Shared Services
The Impact is about things that will happen such as the use of resources or downtime and is taken
from the Number of Users / Store affected by the Change, which indicates the scale of the Change.
The higher the number of Users/Stores impacted is, the greater the impact of the Change.

CBP impacting
Back out can be completed without major impact to service /
users within change window.
Back out is within agreed change window.
5 teams or more to implement or multiple partners. OR more
than 5 days to implement.
CBP impacted
Back out has potential to seriously impact service / users.
Back out could be outside of the agreed change window.

9.8

Approvals

The Approval process has been split into two separate steps for approval:
 Technical Approval & Change Management


9.9

Service (IT Owner / CAB)

Technical Approval and Change Management Approval

Once the Change is fully built including Implementation Tasks, the Change will move to Technical
Approval. The technical approver’s approval covers the approval for the entire change as well as
their task detailed within it.
Extra approvers may be automatically or manually added to the Change technical approval
depending on the information entered. This is to ensure that all of the relevant and approvals are
added at an early stage.
The Change should undergo a review process between the Change Owner and the technical teams
before it is approved. Technical teams have a manager defined regardless of their location or
managing org, the managers receive an approval email to ensure that the approval process is
successful.
Rejection of a Change at the Technical Approval stage will result in the Approval Status being set to
Rejected but will not result in the Change itself being rejected. Notification is sent to the Change
Owner, who will be responsible for deciding whether the Change will now be reworked or cancelled.
Change Owners have the option to put the Change back into Build status to edit the Change and
add any missing information or tasks and resubmit.
A conscious decision has been made to not allow the Change Owner to withdraw and edit the
Change once it has been submitted for Technical Approval. Only once a Technical approver has
rejected the Change can it be amended or cancelled by the Change Owner.
A Change cannot be set to ‘Closed’ status unless is rejected at technical approval, in create or Build
state or completed.

9.10 Status – Change Requests and Change Tasks

9.11 Change Exceptions
If an Exception is created by the Change dates breaching Lead Time, a Pre-Approval is sent to the
Change Exception group before the Change can be progressed to the Technical Approval stage.
Note: Lead times are defined by each business division to correspond with their appetite to risk and
impact, IT define lead times for centrally hosted services.
If the Change is rejected at the Pre-Approval stage, a notification is sent to the Change Owner and
they can either amend the Change by taking it back to Create / Build status to make necessary
amendments or they can Close the Change as cancelled.
There are 3 different types of exceptions:

Exception
Emergency

Retrospective

Definition
Emergency classification should only be used in the event of an open Severity 1
incident with the concept to resolving the open issue.
Retrospective change is used when the proposed activity has already been carried
out and requires documenting. All retrospective change requests require preapproval from the relevant WBA the re Service Manager and in theory should only
be on the back of an open Severity 1 incident.
