1Service level management overview
1.1UNDERSTANDING SERVICE LEVEL MANAGEMENT
1.1.1Defining service level management
Service level management (SLM) is the process that provides the main channel of communication between the customer and the service provider regarding the quality of service provision. In a utopian world, service providers provide services to the customer that support their business activities, meet agreed service level targets, and are cost-effective. However, we don’t live in a utopian world. A formal process is needed to provide a continual dialogue with the customer regarding the fitness for purpose and achieved service levels of delivered services, and to ensure customer satisfaction on the one hand is balanced against efficient service provision on the other.
ITIL defines SLM as the process responsible for negotiating achievable service level agreements (SLAs) and ensuring that these are met. It is responsible for ensuring that all IT service management processes, operational level agreements (OLAs) and underpinning contracts (UCs) are appropriate for the agreed service level targets. SLM monitors and reports on service levels, holds regular service reviews with customers, and identifies required improvements. Although the definition identifies the core activities and more tangible elements of the process, there are other underlying elements that this publication details. When I lecture on SLM, I emphasize additional topics such as relationships, communication, customer perception and other relevant abstract elements – topics that are fundamental to SLM and should be defined and transformed into concrete activities within the process.
Documenting, negotiating, agreeing and monitoring the quality of services, while important, are merely activities that support the overall objective of managing the relationship between the customer and the service provider regarding the provision of services. Relationships, communications and customer perceptions, when integrated with these activities, are the key to building a truly productive relationship based on trust and quality.
1.1.2Service level management and ITIL
SLM is considered one of the core processes in any IT service management framework. While incident management and the service desk function are usually the first to be implemented in organizations wishing to advance their ITIL maturity level, today we see an increasing number of organizations realizing the significance and value of SLM in accelerating their efforts and, as such, moving the SLM process up the queue for process implementation.
Many ITIL consultants and practitioners recommend implementing or improving SLM prior to any other process. This might sound extreme at first, but those who have experience with implementing SLM will agree that it exposes gaps in the service delivery environment, including gaps in established processes. For example, an organization that initially implements incident management will utilize best practice and customize the process to meet the specific needs of the organization while at the same time assuming that, with time, the process will adjust to meet those needs. Unfortunately this is seldom the case, and often process implementations stagnate or even deteriorate as time passes.
With an established SLM process, important inputs from the process would have assisted in getting the incident management process right first time. For example, a detailed understanding of customer requirements, critical services, and service improvement prioritization are only a few of the many important inputs that would focus the efforts of implementing an incident management process – or, for that matter, any ITIL process. I will refrain from stating that SLM is the most important process in ITIL; however, it is the process that has the closest relationship with the customer and continually monitors not only the actual quality of service but the customer’s perceptions of quality and value for money.
The SLM process belongs to the service design stage of the lifecycle, but it’s important throughout the operational stage as well. ITIL defines a service lifecycle that positions SLM in the design phase. This is a very interesting discussion point. Services are strategized through processes such as service portfolio and demand management, which clearly belong to the service strategy phase. Service catalogue and availability management assist in completing the design of the services addressed in service strategy. SLM is indeed a process that assists in the design phase and in fact is one of the primary factors in developing the service catalogue.
Not to dispute the fact that SLM belongs in service design, it is imperative to understand that SLM is an important factor in the service operations arena too. SLA monitoring and service review are prominent operational activities, along with assisting with critical incidents and developing root cause analysis of incidents and problems. The service desk works closely with SLM to interface with end users on an operational level. Therefore, when analysing SLM, make sure to define the process as two-pronged: a process that defines services but also supports the ongoing delivery of services.
Finally, in consideration of the continual service improvement stage of the service lifecycle, I should explain my use of the terms ‘continual process improvement’ and ‘continual service improvement’. When talking about ongoing improvements to the SLM process (and not the wider service), I use the term ‘continual process improvement’. However, when describing the activity in the context of the ITIL service lifecycle, I use ‘continual service improvement’, in keeping with the correct name for that lifecycle stage.
1.1.3Scope of service level management
Traditionally, SLM was the process that owned the SLA, generated service performance reports, and developed the OLAs and UCs. As important as those components are, you will learn that the scope of SLM has matured in recent years, promoting it to the level of vital contributor to a healthy service management environment. The service level manager is no longer an analyst expected to document services and their performance. The service level manager today is expected to carry out management tasks, such as building a relationship with the customer, and negotiating terms and conditions of service quality, and is a respected figure amongst the technical delivery teams.
SLM ensures that services are designed to perform as required by the business and governs those who provide the services to ensure that services are provided as agreed with the customer. This point is important to understand. SLM does not strive for 100% availability of a service but, rather, strives to meet the agreed availability level. The customer will always want a 100% performance for all services; however, it is the responsibility of SLM to agree on service levels that encompass not only the customer’s requirements but also two other important attributes: business requirements and cost (see example provided).
The example illustrates the essence of SLM. This is a process that no longer concerns itself only with maintaining the SLA and generating reports. SLM ensures that services are provided according to the business needs, promote efficiency and are cost-effective. This is achieved through an effective communication platform that SLM provides.
1.1.4The service level management process
In this publication, the SLM process is broken down into five steps, as shown in Figure 1.1.
Each step in the process is considered a process in its own right, or a sub-process of SLM. As Figure 1.1 shows, the SLM process is made up of five interconnecting sub-processes or activities, which are described as follows:
In Part 2, which deals with service design, you will find elaborate definitions of the above processes, and in Part 4 on service operation, each process is defined in terms of its functions, goals and activities. Finally, Part 5 on continual service improvement details the theories and practical activities involved in continually improving the SLM process.
1.1.5Outsourcing engagement versus enterprise
SLM provides the means of communication between a service provider and its customer. The basic assumption is that within any service environment we can identify a function, a process or personnel that provide services. Within the same environment we can identify a function, a process or personnel that receive the services. The structure and size may differ but the main two actors in the service arena are the service provider and the customer.
This publication provides one standard SLM process that strives to fit all organization structures. However, there are two service structures that sometimes require special attention: outsourcing engagement and enterprise. They are defined as follows:
When considering SLM, ignoring the difference between these two service structures (outsourcing engagement and enterprise) is nothing short of reckless. However, it is important to note that SLM as a process is almost identical in both environments and, when a difference does occur, I will point it out and guide you on how to address the matter, whether in an outsourcing engagement or in an enterprise.
1.2PUBLICATION OBJECTIVES AND TARGET AUDIENCE
1.2.1Who should read this publication?
Secrets of Service Level Management serves service level managers, ITIL practitioners, IT service management consultants or any individual who aspires to implement or improve SLM as a process. It is not an ITIL theoretical or foundation publication; rather, it includes advanced material that will allow practitioners to precisely design and implement elements that support SLM.
1.2.2How this publication is different
Many publications that provide guidance on the ITIL framework focus on defining the processes, activities and objectives. Here I provide you with practical guidance on how to implement the process and activities and how to achieve your objectives.
In this publication I approach an element, define it, and continue with detailed guidance on how to achieve the ideal implementation of that element. I have made the text easy to read, drawing on the knowledge of practitioners with years of experience of how to do and, sometimes more importantly, how not to do something.
Secrets of Service Level Management is a practitioner guide on how to successfully implement an effective SLM process, how to take the theory of ITIL and convert it into practice, and how to plan and execute process improvement. I also explain what the challenges are, how to anticipate them and how to overcome them.
1.3HOW TO USE THIS PUBLICATION
1.3.1Publication structure
This publication adopts the ITIL service lifecycle approach. It assumes that in order to implement a process the same steps must be followed as when implementing a service. Firstly the process must be strategized, providing input into the design activities of the process. The subsequent design is then transitioned into its operational state, where the process activities are being executed. The process of implementation is not complete even in its operational state. ITIL suggests a cyclical structure to its lifecycle, signifying that continual service improvement is performed throughout in order to ensure that the process is adjusted for ever-changing service environments and the improvement of local failures (see Figure 1.2).
The chapters of this publication are arranged in accordance with ITIL lifecycle phases. The following describes the content that can be found in each lifecycle phase.
In Chapters 5–11 we examine process elements, including the overall SLM process, resources and functions, SLA structure, service performance measurements and much more. At the end of Part 2, you will hold precise definitions for all tools and procedures of SLM. The design chapters recognize that each organization has its own culture, requirements, procedures and constraints. The guidance provided here will allow you to customize processes and deliverables according to your specific needs.
1.3.2Publication language
I have written this guide in a straightforward and personal style, attempting to ‘talk’ to the practitioner and explain the matter at hand. I aim to act as a mentor to the practitioner and guide them through each activity, acknowledging the fact that many practitioners are international, multicultural professionals whose first language is not necessarily English.
The publication will refer to ‘you’ as the reader in many roles. Sometimes I will refer to ‘you’ as a service level manager, sometimes as project manager and sometimes as an IT service management (ITSM) practitioner. The term used in a particular instance has low significance and I recommend you not to be tied to the role referred to but rather to the method being presented.
There are many terms and definitions that are used differently across organizations, and it is not within the scope of this publication to challenge the correct usage of such terms and definitions. For example, the service provider in some organizations is the IT department or the IT operations or supplier. Similarly, customers may be broken down by functions, departments or business units; but they are still the receivers of the services and are referred to mostly as ‘customers’.
In some instances an effort has been made to distinguish clearly between different meanings of terms and definitions where confusion may arise if an inappropriate connotation is likely. For example, the definitions of ‘customer’ and ‘user’ are occasionally confused. The customer represents a group of users (or end users), signs agreements and pays for the services. The user consumes and merely uses the service on a day-to-day basis.
1.3.3Reference guide
Secrets of Service Level Management covers all aspects of SLM and positions the activities in a logical order for implementation. It is recommended to initiate the implementation with strategic activities that will lead to effective design work and so on. In an ideal world the reader will read the entire publication from start to finish in sequential order. However, this publication dedicates chapters and sections to address process-essential aspects. This allows you to go directly to the chapter that addresses the issue you are looking to learn about. For example, if you are interested in establishing an SLA according to best practice, it is not necessary to read from the beginning until you reach Chapter 8. You are encouraged to use the table of contents or the index to search for topics of interest.
1.3.4Secrets of the trade
I wrote Secrets of Service Level Management with the help of SLM practitioners, solution architects and consultants who dedicated time, outside their daily work, to document the actual practices of implementation of the SLM process. In this publication you will find ‘secrets of the trade’ that allow me to share the personal experiences and perspective of these practitioners on the topic in hand. ‘Secrets of the trade’ show an insight into the world of those experts, providing you with tips regarding the practicality of implementing SLM, and on tackling and overcoming unforeseen challenges.
1.4IMPLEMENTING SERVICE LEVEL MANAGEMENT
My mother is a great cook. My friends used to enjoy many dinners at my house. My friends’ mothers used to ask my mother for recipes that ended up not tasting the same. When my mother was asked about it, she always delivered the same clichéd statement, ‘Love is the secret ingredient’.
Effective SLM is much more than a comprehensive SLA, colourful reports and elegantly formatted documents. All those instruments are simply enablers of the process objective, which is to provide channels of communication between the service provider and the customer and to increase customer satisfaction. The process instruments, which are essential, will not lead to a successful process without the secret ingredient – relationship.
If you are a practitioner or service level manager preparing for process implementation, always keep in mind the overall goal of the process: positive customer perception of service provision. The processes and functions that you design must be the basis of this approach.
Prior to the initiation of the implementation, you should consider the following guidelines:
It is hoped that this publication will help you appreciate SLM as a process that, beyond tracking service levels, provides a platform of communication and networking, influences customer perception, and is a key contributor to the overall health of the service management environment. Good luck in your forthcoming design and implementation activities, and let’s get to work.
