Recovery Types Do nothing - Few, if any, organisations can function effectively without IT Services. Even if there is a requirement for stand-alone PC processing, there is still a need for recovery to be supported. Manual Work-arounds - manual Work-arounds can be an effective interim measure until the IT Service is resumed wherever they are practical and possible. Reciprocal arrangements - Entering into an agreement with another organisation using similar technology. Benefits can exist, in maintaining some reciprocal arrangements, for example, in the off-site storage of backups and other critical information. Gradual Recovery (cold standby) - up to 72 hours, without a re-establishment of full IT facilities. Accommodation fully equipped with power and local network cabling Infrastructure, telecom connections. Fixed or portable facility. When opting for a gradual recovery, consideration must be given to highly customised items of hardware or equipment that will be difficult, if not impossible, to replace. Intermediate Recovery (warm standby) 24 to 72 hour period. It is usually far away (logistics) and shared with 20 to 30 other companies. Use 6-12 weeks. Can be portable, in a trailer. Immediate Recovery (hot standby) provides for immediate restoration. Application systems and communications already available and data mirrored from the operational servers. In the event of a system failure, the Customers can immediately switch to the backup facility with little or no loss of service. System can be used as backup and reporting resource.

Pricing Method/Policy Cost Plus – cost + profit rate Going Rate – comparable to other dept services Market Price – match external supplier price Negotiated Contract Price

ACTIVITIES Monitoring Analysis Tuning Implementation Storage of Capacity Management data – the CDB Demand Management Modeling Application sizing Producing of the capacity Plan

OUTPUTS Availability and recovery design criteria Agreed targets of availability, rel., maintainability Reports on achieved A.R.M Availability monitoring Availability improvements plans

Service Level Management BENEFITS Customer and IT service provider have a clearer view of requirements and responsibilities Commitment on both sides Specific targets to aim for Week areas will be identified Supports supplier management (internal and external) Demonstrable performance indicators Gradual improvements in service quality Better forward planning / both customers and IT Will show where customer/user actions are causing difficulty and identify where working practice need to be improved IT service will be defined to meet Service Level Requirements SLAs can be used as a basis for charging Improved communication between IT and customers Better value for money

Financial Management for IT services BENEFITS Increased Confidence in budgets Accurate information supplied for investment and TCO purposes Increased professionalism and efficiency Warning over or under usage of service Sound business method of balancing IT service provision with business requirements The cost of doing or not doing a Change

Capacity Management BENEFITS Minimize risk of failing to meet SLAs and SLRs More confident forecasting Value to the applications lifecycle Increased efficiency Cost savings and cost avoidance Timely enhancements and upgrades

IT Service Continuity Management BENEFITS The annual spend on ITSM can be controlled Cost justifiable risk reduction measures can be implemented The ability to recover in a controlled manner All staff aware of their role relating to ITSCM Potential lower insurance premiums Meetings regulatory requirements Better business relationships Positive marketing of contingency capabilities Organizational credibility Competitive advantage

Availability Management BENEFITS A single point of accountability for availability is established within the organization IT Services are designed to meet the IT Availability requirements of the business the levels of IT Availability provided are cost justified the levels of Availability required are agreed, measured and monitored to fully support Service Level Management shortfalls in the provision of the required levels of Availability are recognised and appropriate corrective actions identified and implemented a business and User perspective of IT Service Availability is taken to ensure optimal usage and performance of the IT Infrastructure is achieved to deliver maximum benefit the frequency and duration of IT Service failures is reduced over time IT support organisation mindset moves from error correction to service enhancement; from reactive to proactive attitude the IT support organisation is seen to 'add value' to the business.

PROBLEMS ensuring targets are achievable (use existing achievements if known) verifying targets prior to agreement (prior monitoring, pilot SLAs) Monitoring of actual achievement (only agree what can be monitored) Inadequate resources and time (process must be properly staffed and resourced Lack of understanding (educations) Differences in perceptions within the customer community (need to agree relevant targets at all levels) Not enough seniority (give Service Level Manager the appropriate authority) SLA may not be supported by adequate underpinning agreements/contracts (review OLAs and contracts) KEY PERFORMANCE INDICATORS what number or percentage of Services are covered by SLAs are Underpinning contracts and OLAs in place for all SLAs and for what percentage? are SLAs being monitored and are regular reports being produced? are review meetings being held on time and correctly minuted? is there documentary evidence that issues raised at reviews are being followed up and resolved (e.g. via an SIP) what number or percentage of Service targets are being met and what is the number and severity of service breaches? are service breaches being followed up effectively? are service level achievements improving are Customer perception statistics improving? are IT costs decreasing for services with stable (acceptable but not improving) service level achievements? are SLAs, OLAs and underpinning contracts current and what percentage are in need of review and update? CRITICAL SUCCESS FACTORS Meeting Customer Needs And Priorities Adherence To Service Levels Providing Services Cost Effectively Controlling Service Delivery Maintaining Recognized Industry Acceptance For IT Quality Maintaining An IT Service Culture

PROBLEMS Lack of understanding leading to inefficient, overlay expensive or over-complex systems Monitoring tools inaccurate or too expensive Delay in obtaining, or inaccurate, information Difficulty in recruiting staff with accountancy and IT skills Unable to respond to changes quickly enough Lack of management understanding and support

PROBLEMS Unrealistic expectations Vendor influence Lack of accurate information - business data - technical data Distributed environments Level of monitoring to be implemented

Contingency Plan IT infrastructure, comprising the replacement system, plus contracts/agreements necessary for recovery IT Infrastructure Management and operating agreements/procedures during a disaster Personnel - details of those needed at contingency site plus accommodation required Security instructions, emergency contacts and items for home site Contingency site: location, people, facilities, security and transport arrangements Return to normal - dependencies affecting the return

PROBLEMS Defining availability levels that are meaningful to the business Managing internal and external providers is made difficult by lack of agreed availability targets Assessing achievable and cost-effective levels of IT service availability New services are implemented without full consideration of availability requirements Loss of business and reputation due to unstable IT services Lack of accountability

KEY PERFORMANCE INDICATORS Overall cost of delivery per customer Percentage of IT costs not accounted for Dollar value of budget variances/adjustments Percentage of IT financial objectives met IT Service Headcount

KEY PERFORMANCE INDICATORS Resource forecasts - timely production of forecasts - accurate forecasts if trends in resource util. - incorporation of business plans into cap. plan Technology - ability to monitor perf and troughput - impl.
