Why SLAs? ITIL Introduction Service Level Management Implementation Considerations Wrap-up



Why SLAs?



1



Are they being served…?

Where did my IT expense $ go? How does IT support my business? What level of IT service am I getting? IT? Value? Where’s the connection?



Am I getting value for my money?

Opposing Perspectives

Business View

Once IT projects end, it’s tough to see what drives IT costs. IT does not have a good handle on controlling its expense $. I’m unsure of how my IT demands create costs – it’s a mystery. I find it hard to get commitments on IT service levels. Why is this so difficult?

5

IT View

The business is only interested in projects, not operations & maintenance. The business keeps asking us to reduce expense $, while creating more demand. The business often expects something for nothing. The business has unrealistic expectations of service levels. Why is this so difficult?



Why SLAs?

To prevent this:



IT



Service Desk



Business Units

Service Level Management Goals

Develop a business-value basis for IT services Encourage effective business usage of IT services to help manage costs Set a clear, manageable expectation for the businesses regarding the delivery of IT services Embed a measurement culture for IT services Facilitate accountability for the delivery of IT services Facilitate the reuse of service components to simplify service management and operation

7

Achieving the Goals

As always, this requires a combination of: • business alignment • people • process • technology • organization. Are there frameworks we can leverage?

ITIL Introduction

What is the ITIL?

IT Information Library A series of books giving guidance on integrated IT management processes A frame of reference describing IT service management best practices A complete model in the public domain for the delivery of IT services An independent model of IT makers (software and hardware) and the key consulting firms they recognize

10

 DMR Consulting



ITIL – Key Objectives

• To align IT services with the current & future needs of the business, and its customers • To improve the quality of the IT services delivered • To reduce the long-term cost of service provision

SLA versus SLM



SLM

The process in charge of managing the quality and quantity of IT services



SLA

The written agreement between the IT department and its customers describing the characteristics of the services to be delivered



15

 DMR Consulting



Service & Service Catalog

Service

– Not to be confused with technology – Visible services (for SLAs) Access to applications, Printing services, Messaging services, etc. – Non-visible services (for OLAs & UCs) Network services, Infrastructure, etc.



Service catalog

– Collection of all the visible services the IT department can provide its clients



16

 DMR Consulting



Service: something the client can describe in its own terms and is willing (potentially) to pay for



SLRs & SLAs

Service Level Requirement

– Prior to a new service or first stage of an existing service that is not measured – Reflects desired service levels



Service Level Agreement

– Services agreed on with the client that can be measured – Reflects target service levels



17

 DMR Consulting



OLAs & UCs

Operational Level Agreement

– Agreement with internal IT resources to satisfy clients’ SLAs



Underpinning Contract

– Contract with external service provider to satisfy clients’ SLAs.



18

 DMR Consulting



Relationships

– Relationships between clients, service catalog, SLAs, OLAs and UCs

Implementation Considerations



4



Before Starting

The SLM starting point will vary by situation.

IT perception in the organization

– Business contributor or cost center



Organizational culture Business drivers & pain points Maturity of supporting processes

– Incident, problem, change, etc.



Mix of new vs. existing services Mix of internal vs. third-party capabilities

27

 DMR Consulting



Bottom Line

Basically, SLM is about three things:

– Setting objectives (that make sense to business) – Measuring to make sure the objectives are attained – Taking corrective action if needed



This means three main things:

– Understanding the client’s objective (SLR) Whether IT can deliver or not – Measuring current IT service delivery (Service Catalog) – Managing that gap (SLAs, OLAs, UCs)



28

 DMR Consulting



Strategy Hints

Start with a smaller scope

– For example: Critical services, Common corporate services, Focus on one client, etc.



Implement IT internal Service Objectives before formal SLAs or OLAs

– Based on: Industry standards, Own internal standards, etc.

FAQs

How many Service Catalogs per Company/Client?

There should be one Service Catalog for the IT department unless there is more than one service delivery organization.



How many SLAs per Client?

It is normal practice to have a single SLA for each client covering all of the business services selected by the client and the associated enabling services. It is also possible to have more than one SLA for a single client.



What should be in the Service Catalog?

All visible should be fully described in the Service Catalog as well as the interdependencies between services.



31

 DMR Consulting



FAQs

What about non-standard services?

These should be requested using the “Non-Standard Work Request” process.



Who is the owner of the Service Catalog?

While both the business and the IT department are part of the project to prepare the Service Catalog, ownership of the Service Catalog remains with the IT department.



32

 DMR Consulting



Do Not Forget

To make the distinction between visible services and non-visible services To use language the clients and customers understand To thoroughly prepare the awareness campaign in order to define the expectations correctly To ensure communication channels between IT and the business To ensure that measurements and metrics are agreed upon and can be implemented and used To ensure that SLAs are actually backed up by OLAs and UCs (where these are necessary).



33

 DMR Consulting



Keep in Mind

A SLA, by itself, does not improve the services. A SLA is not just a collection of service level indicators. A SLA can harm more than it helps if not done properly! Just like in a marriage, the real work starts after the SLA is signed.
