4Objective
The objective of the change management processThe objective of the change management process is to minimize service downtime by ensuring that requests for changes are recorded and then evaluated, authorized, prioritized, planned, tested, implemented, documented and reviewed in a controlled and consistent manner.

8CAB & ECAB Composition
Change procedures need to specify how the composition of the CAB and ECAB are to be determined.
CAB composition needs to be flexible to ensure business interests are properly represented.
ECAB composition needs to provide the ability, from both a business and technical perspective, to make appropriate decisions in any situationappropriate decisions in any situation.
15
Change Process Models
Models provide the framework for defining the steps needed to handle changes consistently and ff ti l I l deffectively. Includes:
Steps to handle change (including exceptions) Chronological order of steps including dependencies Responsibilities Timescales and thresholds for completion of actions
E l ti d Escalation procedures Approval authority Quality or performance measures and objectives

Emergency Change
Emergency Change Authorization ECAB instead of CAB Levels of delegated authority need to be clearly Levels of delegated authority need to be clearly
documented and understood
Emergency Change Building, Testing and Implementation
Changes allocated to technical group for building As much testing as possible
Emergency Change Documentation Emergency Change Documentation Temporary records at the time with completed records
retroactively

Change Management Tools
Change Ticketing Tool All requirements collected Scheduled for implementation Scheduled for implementation Status updated communicated to stakeholders User generated reports
May be integrated with trouble-ticketing tools, problem-management tools, configuration database which helps to improve efficiencywhich helps to improve efficiency.

Process Improvement Program
Goal of PIP is to achieve the following CSFs: Repeatable process for making changes Make changes quickly and accurately Make changes quickly and accurately Ensure changes are driven by business needs Protect services when making changes Deliver process efficiency and effectiveness benefits
Main activities: Process measurement Process measurement Process reporting Process assessment Process improvement
29
Process Measurement
Performed on a weekly or monthly basis
KPIs established during change management process design collect and evaluate on a regular basis
30
-
16
Process Reporting
Performed on a monthly or quarterly basis
Reviewed by change management staff as well as service, IT and business management
Presents summary information (dashboard / balanced scorecard) based on KPIs
Include trend analysis and potential process issues
31
Process Assessment
Performed on a semi-annual or annual basis
Audit a sample of changes for compliance to process Audit a sample of changes for compliance to process Audit change management process for completeness,
efficiency and effectiveness Evaluate against previous assessment period Benchmark against industry best practices Compare current status with CSFs Establish improvement actionsp Re-evaluate CSFs for next assessment period

Process Improvement
Prepare a Process Improvement Plan which includes:
Deliverables Deliverables Due dates Implementation resources People responsible for completion
33
Examples of MeasuresOperational Metrics:
Number of incidents caused by unsuccessful changes Inaccurate change specifications Incomplete impact assessment Incomplete impact assessment Unauthorized changes & percentage reaction Percentage reduction in time, effort, cost to make
changes Reworks caused by inadequate change specifications Percentage improvement in predictions Percentage improvement in impact analysis and
scheduling
Workloads: Frequency of change Volume of change
34

18
Examples of Measures (cont)
Process Measures: Satisfaction with speed, clarify, ease of use
N b d t f h th t f ll f l Number and percentage of changes that follow formal procedures
Ratio of planned versus unplanned changes Ratio of accepted to rejected change requests Number of changes recorded and tracked using
automated tools Time to execute a changeg Staff utilization Cost against budget
35
Example KPIs
Used to measure the performance of the change management process:
Ch ffi i t Change efficiency rate Change success rate Emergency change rate Change reschedule rate Average process time per change (days) Unauthorized change rate Change incident rate Change incident rate Change labor workforce utilization Change management tooling support level Change management process maturity
36

19
Summarising Measures
Reported to management via a dashboard or balanced scorecard.
Examples:
KPI change success rate calculated as:
number of failed changes / total changes implemented
CSF Protect services when making changes calculated using the KPIs emergency change rate, unauthorized change rate, change incident rate
