Introduction
• Structure– Not a presentation but interactive– Stop for discussion and questions after each
section
• Business Case Activities– Baseline Current Service Management– Define Future Service Delivery and Support– Plan ITIL Implementation– Estimate Benefits and Costs
• Production of the Business Case• Next Steps
Business Case Activities
www.npia.police.uk
Baseline Current Service Management
www.npia.police.uk
Baseline Current Service Management• Identify who will conduct the assessment
– Internal Staff– Use of an external assessor or specialist resource
• Conduct assessment– Gather documentation
• Procedures, Reports, Meeting minutes
– Initial assessment using source material & available documentation
– Confirm using Surveys/ Interviews / Workshops
www.npia.police.uk
ISS4PS Alignment Catalogue
• Service Management section only– Identifies ideal to be achieved (unrealistic to
expect complete conformance)– Describes evidence that is required– For example question 1 asks
• Whether roles and responsibilities are defined for ITIL activities
• To provide job descriptions which align with ITIL responsibilities as evidence
• If this cannot be provided then it is recorded as a deficiency
www.npia.police.uk
itSMF Self Assessment
• Download from http://www.itsmf.com/bestpractice/selfassessment.asp
• Simple questionnaire but more difficult to apply
• Identifies process maturity– Documentation & procedures must not only be
in place but used correctly
• Identify deficiencies
www.npia.police.uk
Process maturity
www.npia.police.uk
Maturity level Requirement
1 Acknowledgement of problems / issue but no procedures available. Prerequisites exist to support the procedure
1.5 Governance and management intent exists for the procedure
2 Procedure available which covers minimum set of activities
2.5 Procedure available which includes integration with other activities
3 Procedure available and repeatable which includes production of required output information
3.5 Working repeatable process includes adequate quality control
4 Adequate timely management information available
4.5 All external and internal interfaces with the process defined and working
5 Fully optimised process which meets customer needs
Impact Assessment
• Assess each deficiency noted– Consequence of deficiency e.g. additional
resource, increased risk, poor customer satisfaction
– Identify related deficiencies– Obtain examples of what has occurred in
operation– Identify tangible and intangible benefits of
rectification– Assess overall cost of rectification & difficulty
• High / Medium / Low
www.npia.police.uk
Identify KPIs
• Establish basic KPIs – Number & Type of Incidents reported– Average Incident Resolution Time – How many unresolved / outstanding Incidents at
the end of a period– Number / type of changes raised / implemented– Number and impact of system outages– Customer satisfaction
• Measure initial KPI baseline then Periodic KPI measurement– Used to measure improvement
www.npia.police.uk
Baseline Current Service Management• Break• Questions / discussion
www.npia.police.uk
Define Future Delivery & Support
www.npia.police.uk
Define Future Delivery & Support – Interim Goals• Long Term Programme not Short Term Fix• Set Measurable Interim Goals
• Illustrate specific achievements (may be small)• Limit desire for a perfect solution – initially aim at 80%• Measure using KPIs
• Generate visible business benefits in year 1• Obtain staff commitment• May require short term tactical approach
• Iterative approach – improve in year 2 and beyond– Build upon success
www.npia.police.uk
Define Future Delivery & Support – Governance
• Define project organisation for the ITIL Implementation project– The Senior Responsible Owner (SRO)– The project manager– The main stakeholders– Key members of the project board– Key project staff including but not restricted to
provision of technical assurance
• Detailed ITIL roles and responsibilities - part of ITIL implementation
www.npia.police.uk
Define Future Delivery & Support• Break• Questions / discussion
www.npia.police.uk
Plan ITIL Implementation
www.npia.police.uk
Plan ITIL Implementation – Triage• ITIL is descriptive not prescriptive
– Misses prioritisation
• Not cherry picking high priority processes– Define work to migrate to future system– Must consider dependencies
• Two basic approaches– Commence with Change Management, slimmed
down CM followed by Release Management– Stabilise via Service Desk/Incident/Problem
approach
www.npia.police.uk
Plan ITIL Implementation – Triage
• Which approach is best ?– Sort list of deficiencies according to severity and
business benefit– Objective is to establish greatest benefit and
business ‘pain’
• Identify quick ‘wins’ as a separate exercise• Consider inter-related dependencies
– CM provides the basis for other disciplines– Build in interface requirements
• No overall winner – adopt Change /CM approach
www.npia.police.uk
Plan ITIL Implementation – Single or multi process• Single process implementation
– Only one discipline at a time– Less resource over a longer period– Cannot deliver significant benefits quickly– More difficult to implement process
dependencies
• Multi process– Concurrent process implementation– Requires more resources, coordination and
planning– Improvements delivered quickly
www.npia.police.uk
Plan ITIL Implementation – Single or multi process• Decision depends on
– The senior management commitment– Budget– Resource availability– The skills and knowledge within the
organisation– The culture and organisational structure– The tools and technology– The demands for 'business as usual‘
• CANNOT DO EVERYTHING ALL AT ONCE
www.npia.police.uk
Plan ITIL Implementation – Single or multi process• Decision depends on
– The senior management commitment– Budget– Resource availability– The skills and knowledge within the
organisation– The culture and organisational structure– The tools and technology– The demands for 'business as usual‘
• CANNOT DO EVERYTHING ALL AT ONCE
www.npia.police.uk
Plan ITIL Implementation – Software Support• Mandatory Requirement
– Total set of functionality to support best practice• No single tool
– CM Database• Central Data repository• Support & enable other disciplines• Single source of Asset Management data
– Service Desk • Interface to CMDB
– Event Management• Review current tools & confirm requirement
– Estimate £100K - £150K• Plan procurement & implementation
www.npia.police.uk
Plan ITIL Implementation – Communication Strategy• Underpins successful ITIL Implementation
– Engage stakeholders, senior management & staff
– Communicate throughout– Include training
• ITIL• Specific
• Produce communications strategy and include activities in plan
www.npia.police.uk
Plan ITIL Implementation- Implementation Plan 1• No Standard Plan but outline provided• State assumptions e.g.
– Dedicated skilled staff available– External Consultancy Support– Timescale estimates
• Identify checkpoints, major activities & dependencies– Then decompose– Bottom level in a Business Case must last no more than
6 months (preferably 2-3 months)• Automate early
– This will effect how procedures are implemented• Ensure communication tasks includedTHIS PROVIDES LOGICAL FLOW & IS NOT A PLAN YET
www.npia.police.uk
Plan ITIL Implementation- Implementation Plan 2• Add Resources
– Initial Resourcing should represent what you would like– Add required external consultancy support– Should also be realistic– Don’t worry about overall timescales too much
• Expect a 3-4 year programme at least• Don’t attempt to compromise activity durations• If you make everything too stringent plan will fail !!
– Result should be recommended option• Do additional variants (options comparison)
– A minimal resourced plan (longest possible timescale)– A maximum resourced plan (shortest possible timescale)
www.npia.police.uk
Plan ITIL Implementation- Implementation Plan 3• Identify delivery of benefits against each
planning option– Different benefit profile for each option– Input into Cost / Benefit Analysis
• Identify risks– Typical risks documented– Identify risks specific to your implementation
• Identify how risks will be monitored and managed– Should be a standard Risk Management procedure
www.npia.police.uk
Plan ITIL Implementation
• Break• Questions / discussion
www.npia.police.uk
Benefits and Costs - Benefits
• Must be real £ and convincing– Not a religious decision
• Three sources of benefit– Benefits experienced by external companies– Benefits experienced by Police Service – Estimated specific organisational benefits
www.npia.police.uk
Benefits and Costs - Benefits
• Identify assumptions e.g– No of users– Average cost of an employee– Total no of incidents per year & average fix time– No of releases per year
• Examine impact analysis statements for each ITIL discipline– Business impact - analyse operational examples– Estimate tangible costs and intangible benefits– Document benefits clearly
• Where possible include operational examples
www.npia.police.uk
Benefits and Costs – CM Benefits• Better overall Knowledge & Control
– Asset inventory & System Configuration• Typical tangible benefits
– Reduce costs of maintenance renewals• 2 - 5% on current maintenance

• Typical intangible benefits– Improved IT service quality – Improved organisational learning through identification of
trends, preventing failures and reducing impact of failures
www.npia.police.uk
Benefits and Costs – Service Level Benefits
• Defines and monitors the level of service to be provided– Provides basis for service improvement– Measures performance of suppliers (internal & external)
• Typical tangible benefits– Reduced no of Incidents due to clarity of Service provision (e.g.
improved efficiency of Service Desk staff by 5%– Improved contract management
• Levies for poor performance• Typical 2% increase in efficiency
– Greater business efficiency as part of an ongoing service improvement programme
• Typical intangible benefits– Increased customer satisfaction– Improvement in service quality though ongoing service
improvement programme
www.npia.police.uk
Benefits and Costs – Availability Management Benefits
• Optimises capability to deliver a deliver a cost effective and sustained level of availability
• Typical tangible benefits– Identification of underperforming services
• Obtain refunds for poor performance– Avoiding or minimising the direct cost of unavailability e.g.
results of a disc crash• Typical intangible benefits
– Assisting effective change and release management– Identifying opportunities to optimise availability (e.g. reduced
availability of an MIS database which can then be specified with less redundant components & omitted from business continuity)
– Increased customer satisfaction
www.npia.police.uk
Benefits and Costs – Capacity Management Benefits• Matches capacity to business need
– Ensure economic provision of services – Reduced risk of performance problems and failure
• Typical tangible benefits– Deferred expenditure – Economic provision of services – unnecessary spare capacity not
maintained, use of existing capacity optimised– Planned buying with potential for negotiating discounts
• Typical intangible benefits– Reduced risk to new applications through application sizing and
management– Reduction in urgent changes to increase capacity– Improved management information to support forecasting
www.npia.police.uk
Benefits and Costs – Business Continuity Benefits• No immediate cost savings – an insurance premium• Difficult to estimate
– Cost of disaster * probability of occurrence• Cost = (Downtime * No of users * Hourly rate) + Rectification cost
– A reasonable assumption is that a significant disaster will occur once in 10 years (i.e. 10% pa)
• Typical tangible benefits – Compliance with the Civil Contingencies Act – a Legislative
Directive – Reduction / removal of risks associated with business continuity
• Typical intangible benefits– A continued guaranteed high level service to the business– Real-time alignment of IT with business needs and objectives
though improved management of critical business functions
www.npia.police.uk
Benefits and Costs - Costs
• Cost resources on each project plan at appropriate rates– Add consultancy costs as appropriate– Identify different cost profiles
• Add software automation costs– Large Windows server– Software– Add maintenance (8% pa)– Probably £100-£150K
