SLM – Overview

What is an SLA ?A written agreement between an A written agreement between an

IT Service provider and the IT IT Service provider and the IT Customer(s), defining the key Customer(s), defining the key service targets and service targets and responsibilities of both partiesresponsibilities of both parties

Goal The goal for SLM is to maintain and improve IT Service quality, through a constant cycle of

agreeing, monitoring and reporting upon IT Service achievements and instigation of actions to eradicate poor service - in line with business or Cost justification.

Scope All IT services And

- Contacts with Suppliers- Operationnal Level Agreements

Service Level Management - Benefits

Benefits IT Services are designed to meet Service Level Requirements improved relationships with satisfied Customers both parties to the agreement have a clearer view of roles and responsibilities there are specific targets to aim for and against which service quality can be

measured, monitored and reported IT effort is focused on those areas that the business thinks are key IT and Customers have a clear and consistent expectation of the level of

service required (i.e. everyone understands and agrees what constitutes a ‘Priority One’ Incident, and everyone has a consistent understanding of what response and fix times are associated with something called 'Priority One')

service monitoring allows weak areas to be identified, so that remedial action can be taken (if there is a justifiable business case), thus improving future service quality

service monitoring also shows where Customer or User actions are causing the fault and so identify where working efficiency and/or training can be improved

SLM underpins supplier management (and vice versa) -

SLM : implementing the process (1)

Produce a service catalogue A service is one or more IT systems wich enable a business process Define a hierarchy Separate services seen by the customer (business service) and services not

seen by the customer (infrastructure, system, network application services) A service could be defined as a CI (Configuration Item)

SLM : implementing the process (2)

Expectation Management Satisfactin = Expectation – Perception SLA are just documents and themselves doesn’t improve the quality

level Support of business managers to to manager excessive or unrealistic

demands (costs…) SLA Structure

Service based : mailing service Customer based : finance department Multi-levels SLA : coprporate level + customer level + service level

Establish Service Level Requirements and Draft SLA Iteractive process based on a first outline draft (as a starting point) Negociate requirements vs charging

Wording of SLAs Clear and concise without ambiguity

SLM : implementing the process (3)

Seek agreement With customer representatives Care about the current issues. Establish long term

requirements. Start with a pilot SLA if no previous experience Identify customer requirements at all levels (cost,

responsivenss, availability…) Consult IT provider representatives to be sure that targets are

realistic and achievable Take into account suppliers contractual implications

Establish monitoring capabilities All targets in the SLA must be monitored and measured. Monitoring must match the customer perception Links to the service desk

C O N N E C T I N G B U S I N E S S & T E C H N O L O G Y

SLM : SLA contents (1)

Introduction- parties to the agreement - title and brief description of the agreement - signatories - dates: start, end, review - scope of the agreement; what is covered and what is excluded - responsibilities of both the Service Provider and the Customer- a description of the Services covered.

Service hours- the hours that each service is normally required (e.g. 24x7, Monday to

Friday 08:00 - 18:00) - arrangement for requesting service extensions, including required notice

periods (e.g. request must be made to the Service Desk by 12 noon for an evening extension, by 12 noon on Thursday for a week-end extension)

- special Hours (e.g. public holidays) - service calendar.

C O N N E C T I N G B U S I N E S S & T E C H N O L O G Y

SLM : SLA contents (2)

Availability- Availability targets within agreed hours, normally expressed as

percentages - measurement period and method must be stipulated. This may be expressed for the overall service, underpinning services and critical components or all three. However, it is difficult to relate such simplistic percentage Availability figures to service quality, or to Customer business activities. It is therefore often better to try to measure service UnAvailability in terms of the Customer's inability to carry out its business activities. For example, 'sales are immediately affected by a failure of IT to provide an adequate POS support service'. This strong link between the IT Service and the Customer's Business processes is a sign of maturity in both the SLM and the Availability Management processes.

Reliability- usually expressed as the number of service breaks, or the Mean Time

Between Failures (MTBF) or Mean Time Between System Incidents (MTBSI).

Version 2004ITIL-Part2-IntroductionServiceSupport

C O N N E C T I N G B U S I N E S S & T E C H N O L O G Y

SLM : SLA contents (3)

Support- support hours (where these are not the same as Service hours) - arrangement for requesting support extensions, including required notice

periods - special hours (e.g. public holidays) - target time to respond, either physically or by other method (e.g. telephone

contact, e-mail), to Incidents - target time to resolve Incidents, within each Incident Priority - targets varies

depending upon Incident priorities. Throughput

• Indication of likely traffic volumes and throughput activity (e.g. the number of transactions to be processed, number of concurrent Users, amount of data to be transmitted over the network). This is important so that performance issues which have been caused by excessive throughput outside the terms of the agreement may be identified.

Transaction response timesTransaction response times target times for average, or maximum workstation response times (sometimes expressed target times for average, or maximum workstation response times (sometimes expressed

as a percentile - e.g. 95% within 2 seconds). as a percentile - e.g. 95% within 2 seconds).

SLM : SLA contents (4)

Batch turnaround times times for delivery of input and the time and place for delivery of output.

Change• targets for approving, handling and implementing RFCs, usually based upon

the Category or Urgency/priority of the Change.

IT Service Continuity and Security a brief mention of IT Service Continuity Plans and how to invoke them, and

coverage of any security issues, particularly any responsibilities of the Customer (e.g. back-up of free-standing PCs, password Changes)

details of any diminished or amended service targets should a disaster situation occur (if no separate SLA exists for such a situation).

Charging details of the charging formula and periods (if charges are being made). If the

SLA covers an Ouitsourcing relationship, charges should be detailed in an Annex as they are often covered by commercial in confidence provisions.

C O N N E C T I N G B U S I N E S S & T E C H N O L O G Y

SLM : SLA contents (5)

Service reporting and reviewing- the content, frequency and distribution of service reports, and the

frequency of service review meetings.

Performance incentives/penalties- Details of any agreement regarding financial incentives or

penalties based upon performance against service levels. These are more likely to be included if the services are being provided by a third-party organisation. It should be noted that penalty clauses can create their own difficulties. They can prove a barrier to partnership if unfairly invoked on a technicality and can also make service provider staff unwilling to admit to mistakes for fear of penalties being imposed. This can, unless used properly, be a barrier to effective Problem solving.

SLM : Key Performance Indicators and metrics

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? What number or percentage of Services targets are being met

and what is the number and severity of service breaches? 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?

IT Accounting (1)

Business Perspective Charge for IT services or not ?

Different organisations Accounting Centre (costing inputs) Recovery Centre (costing outputs / services) Profit Centre (separate business entity)

- Sufficient autonomy- Outsourcing- Risk : the Customer becoming aware that the IT organisation is 'making a profit' from them

Building the cost models To calculate the costs of IT Service provision, it is necessary to design a framework in which all known costs can be recorded and allocated to

specific Customers, activities or other Category. This is called a Cost Model

Total Cost of Ownership The Gartner Group pioneered a method of calculating the costs of a

product or service with the title of 'Total Cost of Ownership' (TCO). The most widely known example was that for Personal Computers. In an

era where the price of a PC on a desk had fallen to $2,000, Gartner demonstrated that the 5-year cost of a PC, when taking into account purchasing overheads, upgrades, maintenance, a proportion of support staff and Service Desk costs, disposal etc. was closer to $35,000

Charging (3)

Case Study : Discouraging use of services A company provided its Users with a dedicated, outsourced Service Desk facility.

The vendor charged the company on a per-call basis. The charging policy was to recharge all IT spending to the business on the basis of true cost.

Once the Service Desk was in place, Customers realised that they could reduce their costs by not placing Service Desk calls. Some business managers instructed their Users not to use the Service Desk, or to route all issues through a single, local support person.

Decreasing the total number of calls decreased the calculated charges to the Customer but did not reduce overall price of the service by the same amount. It also resulted in:

- increased wasted time for Users - reduced effectiveness of IT systems - poor perception of the IT Services and the IT organisation - additional work for the IT organisation to discover problems - reduced leverage in negotiating service costs with the outsourcing vendor.

Resolution- The charging method was changed to one in which a fixed fee per User was

negotiated, based upon an estimated call rate taken from previous years' volumes and business predictions. This charge was reviewed quarterly to check that call levels were within agreed thresholds.

C O N N E C T I N G B U S I N E S S & T E C H N O L O G Y

Security management - essence

Security Management is responsible for continually delivering the Service on an agreed security area with the customer agreement

Security Management focuses on the integrity of data and the unauthorized use of it. It’s goals is to keep information reliable, secure and available, and prevent unauthorised use.

42

Version 2004ITIL-Part2-IntroductionServiceSupport

C O N N E C T I N G B U S I N E S S & T E C H N O L O G Y

Security Management - definitions

Security Management is part of Information Security (BS 7799) and aims to ensure the safety of information

Terms used: Safety : refers to

not being vulnerable to known risks, avoiding unknown risks where possible

The tool to provide this is Security : which aim is to protect the value of information.

This is done by: Confidentiality : protecting information against unauthorised access and use, Integrity : accuracy, completeness and timelines of information, Availability : the information should be accessible at any agreed time.

43

Version 2004ITIL-Part2-IntroductionServiceSupport

C O N N E C T I N G B U S I N E S S & T E C H N O L O G Y

Security Management - justification

• Internal : an organization can only function properly if she has the disposal of the right and complete information

• External : The processes of an organization deliver products and services which are made for a certain goal (competitive advantage). Security is an important condition to an adequate information flow to realise these processes.

Good security ads value to the continuity of the business
