Introduction Purpose This book is designed as a quick reference for ITIL® 2011. It is not intended as an overview of ITIL® 2011 but merely as a memory jogger. It is suggested that you first familiarize yourself with the ITIL® 2011 documentation before using this book. This book contains references to more detailed material found in ITIL® 2011. Audience This book is intended to be used by anyone involved in planning, consulting, implementing, or testing an ITIL® 2011 implementation. Organization of the Book This book summarizes each of the ITIL® 2011 books. Each book in the ITIL® 2011 series represents a single stage in the lifecycle of an IT service. The first and last books in the series, Service Strategy and Continual Service Improvement, do not contain rigorously-defined processes, but instead describe a set of practices that may be used during those stages of the service lifecycle. The second, third, and fourth books in the series, Service Design, Service Transition, and Service Operation, contain rigorously-defined processes. The subsequent chapters in this book each summarize one of the ITIL® 2011 books. The Service Strategy and Continual Service Improvement chapters contain the following structure: x x x x

Service Strategy Brief Description Service Strategy describes an IT organization’s high-level approach to providing services. First, the IT organization must identify the market for its services. This, in turn, drives the identification of services offerings as well as the strategic assets that will constitute those services. Envisioned services will be added to the service portfolio. These identified services will continue to be pursued until they are finally chartered for design (and development), which moves those services into the Service Design stage. Supporting this overall activity is the need to determine the IT organization’s overall approach to providing services. This may include internal providers, external providers, a shared approach, preferred providers, etc. In addition, several practices play a part in determining the overall service strategy, including financial management, demand management, and risk management.

BPMN Workflow
Architecture Considerations This process was originally a loosely-defined set of activities in ITIL v3 but has now evolved to a full-blown process. Strategy Management is a needed process, but is still defined at a very high level. More work needs to be done to make this process actionable.

Key Concepts Application portfolio – The entire set of IT applications, regardless of status in the application lifecycle. This may be implemented as part of the CMS or the service portfolio. Customer agreement portfolio – The entire set of service agreements and other contracts between the service provider and its customers. Customer portfolio – The entire set of customers who receive IT services from an IT service provider.
ITIL® 2011 At a Glance
Market space – A description of the IT customer market, including a description of customer needs, that may be used to determine a set of IT services for that market. Project portfolio – The entire set of IT projects, regardless of status in the project lifecycle. Retired services – The subset of the service portfolio consisting of those services no longer available to customers. Service catalog – The subset of the service portfolio consisting of those services currently available to customers. Service model – A model of the interactions between service assets and customer assets within a service or set of services to create value to the customer. Service pipeline – The subset of the service portfolio consisting of those services not yet available to customers. Service portfolio – The entire set of services managed by a service provider, regardless of status in the service lifecycle. BPMN Workflow
Architecture Considerations This process focuses on the management of the Service Portfolio. However, there are other portfolios to be managed as well, including the Customer Portfolio, Customer Agreement Portfolio, Application Portfolio, and Project Portfolio. This process could be improved by being renamed to “IT Portfolio Management” and the scope broadened to manage all portfolios.

Key Concepts Charging policy – A policy that defines how services and other items will be calculated and charged. Charging process – The approach for deciding how to charge customers and bill them. Cost center – An organization or project against which IT costs are expensed. Using this approach, IT customers are not charged for services. IT service providers can be paid for using either a cost center or a profit center.
ITIL® 2011 At a Glance
Cost unit – Things that can be easily counted while assigning costs for a service. Cost units are the smallest items that can be counted within a cost element. For example, within the cost element “training”, cost units could be instructors, training manuals, or meals. Enterprise Financial Management – Financial management applied to the entire enterprise. Financial management for IT services is a subset of enterprise financial management. External funding – Funding that is obtained from services sold to external customers. Financial Year – A consecutive 12 month accounting period. Funding model – An approach to how and when funding is available for a service provider. Funding models include rolling plan funding, trigger-based funding, and zero-based funding. Internal funding – Funding that is obtained from other business units in the same organization. Profit center – A business unit that charges for IT services. A service provider can be organized as either a profit center or a cost center. A profit center can charge to make a profit, operate at a loss, or just cover costs. Rolling plan funding – A funding plan for a fixed length of time (i.e., cycle) and is used repeatedly for additional cycles. This type of funding is typically used for specific projects. Trigger-based funding – A funding plan that initiates when a specific event occurs, such as a request to upgrade a service. Zero-based funding – A funding plan that allocates costs to a specific budget amount, then recovers those costs from costs transfers from other business units. This is the most typical funding plan for IT services.

ITIL® 2011 At a Glance
BPMN Workflow
Architecture Considerations Financial Management is a part of any major organization. ITIL calls this Financial Management for IT Services to distinguish it from other types of Financial Management within the enterprise. Although this is a useful distinction, the same could be said of many other ITIL processes. For instance, Change Management is a process found in many areas of the enterprise, not just IT, yet ITIL does not call that process “Change Management for IT Services”. The phrase “for IT Services” should merely be an implied part of each ITIL process. An important part of Financial Management not described in ITIL is advisory aspects of Financial Management such as providing financial assessments for change requests, financial feasibility to new projects or portfolio proposals, etc.

Key Concepts Business Relationship Management Process vs Business Relationship Manager Role – The process is focused on maintaining appropriate relationships between the IT organization and its customers and service providers. However, the role is often involved in representing other processes with customers, such
ITIL® 2011 At a Glance
as Service Level Management and Service Portfolio Management. Customer Satisfaction – The practice of taking actions to meet and exceed customer expectations. Service Requirements – Customer wants and needs related to an IT service. Complaint – Negative feedback from a customer that is an important input to continual service improvement. Compliment – Positive feedback from a customer that is an important input to continual service improvement. BPMN Workflow
Architecture Considerations As a new ITIL process, Business Relationship Management needs more architectural rigor. The two ill-named activities do not adequately describe the kinds of work that must be done in Business Relationship Management, such as identifying contacts, managing contact information, defining customer and service provider considers, monitoring and tracking issues, etc.
23
24
ITIL® 2011 At a Glance
Other Practices Risk Management – Identifying, evaluating, and determining acceptable responses to risks. Organizational Change – The transition of an organization from a current state to a future state. At an enterprise level, this is often referred to as Change Management, not to be confused with ITIL (and other) Change Management. Six Sigma – A data-driven methodology for reducing defects to near-zero. Program and Project Management – The processes for initiating, coordinating, and monitoring ongoing programs and timelimited projects. Governance – The approach to ensuring that policies and strategy are adhered to. Quality Management System – An approach to ensuring that an organization meets targeted quality levels. Balanced Scorecard – A tool that breaks down a strategy into key performance indicators.
25
Service Design Brief Description Service Design is a stage in the service lifecycle in which a new or modified service is developed and made ready for the Service Transition stage. The primary effort of this stage is the design (and development) of the service. This include defining service requirements, designing the service solution, evaluating alternate suppliers of the service, and integrating existing service assets or creating them from scratch into a service. Service Level Management provides the interface to IT customers in the collection of requirements. Supporting processes such as Availability Management, Capacity Management, Information Security Management, and IT Service Continuity Management are consulted to make sure the envisioned service will meet service level targets and expectations. Supplier Management manages relationships with potential service providers. As the service progresses through this stage, the Service Catalog is updated with new information about the service, including status changes in the service. The Service Catalog is that part of the Service Portfolio that can be viewed by IT customers. It is also an instrument of Service Level Management to enter into discussions with IT customers about new service requirements or about the initiation of a service level agreement.

Key Concepts Service – A collection of IT systems, components, and resources that work together to provide value to IT customers. Service Design Package – The collection of all information and documentation about a service through each stage of its life cycle. There is a new service design package whether the service is new, updated, or retired.
ITIL® 2011 At a Glance
Design balance – The goal of Design Coordination, which is an equilibrium of utility, warranty, standards compliance, and efficiency in developing and delivering the service. BPMN Workflow
Architecture Considerations Design Coordination, a new ITIL process, is not a wellrecognized industry process. It seems to have been created because there was no overall process for managing the development of services or other IT products. This process should be replaced by a Product Management or Service Product Management process which defines the product vision, manages overall product development, determines when updates or new releases are needed, and ensures deployed products are kept at the right service level.

Key Concepts Business Service Catalog – The collection of IT services that directly enable processes that are part of the business. Hierarchy of services – A network of services that support business processes (business services) and services that enable those business services (technical services). Service – A collection of IT systems, components, and resources that work together to provide value to IT customers. Service Catalog – The collection of IT services currently provided to IT customers.
ITIL® 2011 At a Glance
Service Package – An in-depth description of an IT service available through the Service Catalog. Service Portfolio – The collection of all IT services, including those in the pipeline, those currently being delivered, and those that have been retired. Technical Service Catalog – The collection of IT services that support business processes. Types of service – A qualification of the services in the service catalog. Services should be put into different categories. The most useful categories are customer-facing services and supporting services. BPMN Workflow
Service Catalog Management Service Catalog Management exists primarily because of the prominence of the Service Catalog within ITIL. In reality, Service Catalog Management is nothing more than the administration and management of an IT application. If this line of thinking were carried through, there would be processes for administration of applications such as the CMDB, the Service Desk, the Operations Bridge, or others.

Architecture Considerations Service Level Management, as defined in ITIL, suffers from having too many activities. These should be reduced a bit, since five to seven activities are typically about right for comprehensibility to a broad audience. However, the process also suffers from the fact that there are two primary types of work being carried out in the process. The first type is the establishment of a service level agreement with a customer plus the accompanying work, such as creating OLAs and underpinning contracts, monitoring the service levels, and carrying out service reviews. The second type of work is responding to complaints, improving customer satisfaction, and developing relationships. This second type of work actually overlaps with Business Relationship Management and should be relegated to that process. One ITIL-defined activity, Defining SLA Frameworks, is actually the kind of work that should go into the definition and setup of that process. Every process in ITIL should have an activity to define and implement process roles, work product templates, metrics, procedures, etc. but that kind of work is generally missing.

Architecture Considerations Capacity Management lacks the kind of single-thread work found in Incident Management, which is typically responding to individual incidents. Instead, Capacity Management primarily carries out planning and responding to a variety of capacity-related requests. The activities prescribed by ITIL overlap and should be refactored so the activities can be better sequenced.

Architecture Considerations This activities in this process were structured to represent the life cycle of a supplier relationship, from establishing a supplier contract, through managing the ongoing relationship, to the end of the supplier contract. Unfortunately, the process does not cover procurement from the supplier, which is missing from ITIL altogether. Procurement should be a part of this process. In addition, this process contains an activity to manage the Supplier and Contract Management Information System.

Service Transition Brief Description The service transition stage readies a new or changed service for operation. The primary activity done during this stage is Transition Planning and Support. This process plans all of the activities that must take place to put the service into production. This may involve the creation of a number of RFCs that will carry out all necessary changes (Change Management) and deployments (Release and Deployment Management). Prior to moving the service into production, there may be a period of testing and validating the service to ensure sufficient quality of the service. An overall evaluation framework is used by transition planning and support to determine if the service is still in an acceptable state to proceed or must be remediated in some manner. As the service is readied for production, various configuration items and assets must be assembled and configured. Information about all of these CIs and assets, as well as the relationships between all of these elements, must be maintained in order to provide the best support for the service. Knowledge about the services and underlying CIs and service assets is collected during this stage and subsequent stages in order to provide effective support for service faults.

Service Operation Brief Description In the Service Operation stage, a service is available for IT end users. During execution of the service, it is monitored to determine service levels as well as to look for operational faults. Operational faults may be detected as events from service monitoring. Those events may be resolved within Event Management or may be escalated to Incident Management to be resolved by Service Desk personnel. In either case, the event is recorded as an incident and the service is restored as quickly as possible via either a workaround or some other resolution. Faults may also be detected by users, who may contact the Service Desk to log an incident. The Incident Management process is used by the Service Desk to get the service restored to the user as quickly as possible. The Problem Management process supports the Incident Management process by looking for incident trends (problems) and resolving root causes of those problems. This process also proactively addresses any faults not yet previously identified. The user may also contact the Service Desk to carry out simple, virtually risk-free actions (service requests) that cannot be performed by the user (Request Fulfillment) or to provide access to services or service assets (Access Management).

Key Concepts Event Correlation – Various system monitoring tools generate events according to predefined event generation rules. The usefulness of event management is closely tied to how well these rules are defined. Tightly constrained rules will not generate enough events to identify many failures, whereas loosely constrained rules will generate many false positives.
ITIL® 2011 At a Glance
Event Filtering – Ignoring events that are of less significance to focus on events of greater significance. Event response – Some events may have an automatic response associated with the event, such as restarting a process. Other events may require manual intervention, such as incident management or creation of an RFC. Event rule sets – Categories of rules defining how event messages are processed and evaluated. Monitoring – Monitoring is different from event management. Monitoring determines the status of a configuration item or service, whereas event management identifies changes in status of those CIs and services that represent faults within the IT infrastructure. Types of events – The three primary types of events include informational events (provides information only), warning events (unusual situations that do not warrant immediate action), and exception events (unusual situations that warrant immediate action). BPMN Workflow
Architecture Considerations Event Management has too many activities at the highest level.

Key Concepts Classification – Grouping similar types of incidents into categories. Escalation – Incidents that cannot be resolved by available resources are escalated either to those with greater skills (functional escalation) or to those who are at higher levels of management (hierarchical escalation). Incident models – Similar types of incidents may follow similar paths to resolution. For this reason, predefined workflows for specific types of incidents may be created.
ITIL® 2011 At a Glance
Major incidents – Some incidents are of such magnitude that they are treated individually. Such an incident may be treated as an individual problem in Problem Management. Prioritization – The relative impact and urgency of an incident, where impact is the effect the incident has on the business, and urgency is how long it will take for the incident to have that effect. Recovery – Returning a configuration item to its working state after resolution Repair – Replacing or fixing a configuration item Resolution – Addressing the root cause of an incident or problem via a repair or a workaround. Timescales – A time period in which an incident should be resolved or escalated. Because incident management is focused on rapid restoration of services, timescales are important. BPMN Workflow
Architecture Considerations Both categorizing and prioritizing incidents are closely related because they determine which team will respond to the incident and how quickly they will do so. These activities should be merged together to make room for other common activities such as creating the process framework and continuous improvement of the process.

BPMN Workflow
Architecture Considerations ITIL has always suffered from the lack of a process that specifically serves as the front-end for the service desk. The Request Fulfillment should serve that purpose, but it is not explicitly described that way. This leads to all kinds of religious debates among ITIL adherents concerning whether Incident Management or Request Fulfillment is the first process to receive user contacts to the service desk. This process should be explicitly architected (and possibly renamed) so it is clear that all initial user contacts with the service desk come through this process.

Key Concepts Access – the ability to make use of a specific configuration item. There may be different types of access, such as read, write, execute, etc. Directory services – An application that records the rights given to each identity and allows modifications to those rights. Identity – the name of a user or group. Access rights are granted to identities. Rights – permission given to an identity.
ITIL® 2011 At a Glance
BPMN Workflow
Architecture Considerations There needs to be more support for managing user identitities. Two specific areas that should be addressed include the following: x
x
Periodically, there is a need to audit user identities and determine if there are any that need to be removed. Users sometimes leave the organization without their identity being removed. Also, duplicate or temporary identities may exist that are no longer needed. Group identities need to be managed, as group members typically change over time.

Monitoring and Control – The cycle of service monitoring and response. Service Operation Functions A “function” is an abstract organizational unit within an IT organization. It represents a real organization or group, but not a process. A function may use one or more IT processes or practices to carry out its objectives. There are five primary functions within Service Operation, some, of which, are divided into smaller functions.

Continual Service Improvement Brief Description During the Continual Service Improvement stage, the IT organization collects data and feedback from users, customers, stakeholders, and other sources to enhance services and how they are provided. This involves the use of a seven-step improvement process that collects data, analyzes the data, provides recommendations, and implements those recommendations. In support of the improvement process, Service Level Management collects information from IT users and customers and data from the operation of the services. Service measurement and reporting provides standard vehicles for describing the performance of the services. Finally, all service improvements must be scrutinized according to whether they meet the needs of the business and provide an overall return on investment.

Architecture Considerations The Seven Step Improvement Process is a generic process that can be applied to any context. It is unfortunate that an entire book is devoted to this process. Other improvement processes exist in other context that are just as suitable. Every other process should have an improvement activity that assesses the process and looks for ways to improve it. Therefore, this improvement cycle should be built into every other process. Additional CSI Roles Business Relationship Manager – See the chapter on Business Relationship Management.
