Outlines to be discussed…..
• ITSCM-DRM
• Information Security Management
• Change Management
• Service Transitions
ITSCM – DRM
• IT Service Continuity Management
• Ensures resumption of services within agreed
timescale
• Business Impact Analysis informs decisions about
resources
• E.g. Stock Exchange can’t afford 5 minutes downtime but 2
hours downtime probably wont badly affect a
departmental accounts office or a college bursary
Standby for liftoff...
• Cold
• Accommodation and environment ready but no IT
equipment
• Warm
• As cold plus backup IT equipment to receive data
• Hot
• Full duplexing, redundancy and failover
Information Security Management
• Confidentiality
• Making sure only those authorised can see data
• Integrity
• Making sure the data is accurate and not corrupted
• Availability
• Making sure data is supplied when it is requested
Change Management
• A change is a modification, addition, or removal of anything that
could impact IT services.
• This includes
• Addition
• Modification
• Removal of approved, supported or base lined H.W
• Network
• software
• application
• environment
• system
• desktop build or associated documentation
Reasons for Changes
Purpose of Change Management
• Control the lifecycle of all changes
• Help in making beneficial changes with minimum disruption to IT
services
Objectives of CM
• Respond to business and IT requests to ensure alignment of services
with business needs
• Ensure that changes are introduced in a controlled manner, thus
optimizing business risk
• Implement changes timely and successfully to meet business needs
• Use the standard processes and record every change
Scope of CM
• Any changes to all architecture , tools, metrics, processes and
documentation
• Addition, removal or modification of a service or a configuration item
or an associated documentation
• Changes to any of the five aspects of service design
• Build
• Deployment
• Testing
• User acceptance
• Bed-in (optimize)
Change Model
• A change model refers to pre-defined set of steps, policies and
procedures for assessing, authorizing and executing a specific type of
change. Change models should include the following:
• The steps to handle the change
• The chronological order of the steps
• Defined roles and responsibilities
• Thresholds and timescales for completion of the actions
• Escalation procedures
Change Management
 Respond to customers changing business
requirements
 Respond to business and IT requests for change that
will align the services with the business needs
 Roles
 Change Manager
 Change Authority
 Change Advisory Board (CAB)
 Emergency CAB (ECAB)
 80% of service interruption is caused by operator
error or poor change control (Gartner)
Change Types
• Normal
• Non-urgent, requires approval
• Standard
• Non-urgent, follows established path, no approval needed
• Emergency
• Requires approval but too urgent for normal procedure
Change Advisory Board
 Change Manager (VITAL)
 One or more of
 Customer/User
 User Manager
 Developer/Maintainer
 Expert/Consultant
 Contractor
CAB Considers 7R’s of Change Management
For proper impact assessment and understanding of benefits to risk,
answers to the following seven questions are important.
• Who raised the change?
• What is the reason for the change?
• What is the return required from the change?
• What are the risks involved in the change?
• What resources are required to deliver the change?
• Who is responsible for the build, test and implementation of the change?
• What is the relationship between this change and other changes?
Key Terminologies of CM
• Remediation planning: it refers to a recovery plan to a known state
after a failed change or release
• Service change: refers to the addition, modification or removal of an
authorized, planned or supported service component and its
associated documentation
• Request for change: it is a formal request for a service change and it
can be raised or issued by anyone involved in the service.
• Change proposal: it is raised for major changes with significant
organizational or financial effects
Change Proposal
Change management process-Change flow
Change Manager- Responsibilities
• Ensures process is followed and authorizes minor changes
• Identifies key stakeholders, coordinates and runs CAB Meeting
• Produces change schedule
• Coordinates change, build, test and implementation
• Reviews or closes changes
• Initiates post implementation review meetings.
Change Metrics
Service Transition
• Build
• Deployment
• Testing
• User acceptance
• Bed-in (optimize)
Good service transition
 Set customer expectations
 Enable release integration
 Reduce performance variation
 Document and reduce known errors
 Minimise risk
 Ensure proper use of services
 Some things excluded
 Swapping failed device
 Adding new user
 Installing standard software
Thank You
For Your Patience
