ITSM Practises and frameworks

Incident Management

1. Definition and Objectives

   Incident Management promptly identifies, analyzes, and resolves IT service disruptions to minimise their impact on business operations. The objectives of incident management include restoring regular service operations, minimising downtime, and ensuring efficient and effective handling of all incidents.

2. Incident Lifecycle and Process Flow

   The Incident Management lifecycle typically includes the following stages:
   1. Incident Identification: Detection and reporting of an incident by users or automated monitoring systems.
   2. Incident Logging: Accurately capturing essential details of the incident, such as the impacted service, description, and priority.
   3. Incident Categorisation and Prioritisation: Categorising each incident by the service defined in the service catalog, assessing the impact and urgency of the incident to determine its priority level.
   4. Incident Matching to Problems or Known Errors: Matching all incidents to problems provides valuable data for problem management and a link to the history of past incident resolutions.
   5. Investigation and Diagnosis: Analyzing the incident to identify potential resolution.
   6. Incident Resolution and Recovery: Implementing appropriate measures to resolve the incident and restore service. An accurate incident record is a primary input to Problem and Continuous Improvement Practise activities.
   7. Incident Closure: Confirm the successful resolution of the incident and quality documentation of the details.

3. Roles and Responsibilities

   Incident Management key roles and responsibilities include:
   1. Incident Practise Owner: The one person responsible for the Practise.
   2. Incident Manager: Oversees the Incident Management Practise within an IT service organisation, coordinates resources, and ensures timely resolution.
   3. Service Desk/First-Line Support: Level 1 initial user contact and incident owner logs and provides diagnoses of incidents, aiming to resolve them at first contact. The best practise is that the Service Desk is the Single Point of Contact (SPOC) for all users and customers.
   4. Technical Support Teams: Levels 2 and 3 provide specialised expertise to investigate and resolve escalated incidents.
   5. Users: Report incidents to the Service Desk and provide necessary information for incident resolution.

4. Key Performance Indicators (KPIs) and Metrics

   Common KPIs and metrics for incident management include:
   1. Incident Response Time: The time to acknowledge and respond to an incident.
   2. Incident Resolution Time: The time taken to resolve an incident and restore standard service.
   3. First Contact Resolution Rate: The percentage of incidents resolved during initial user contact at Level 1.
   4. Incident Escalation Rate: The frequency at which incidents are escalated from Level 1 to higher-level support teams.
   5. Customer Satisfaction: Feedback from users and customers regarding their satisfaction with incident resolution.

5. Incident Management Tools and Technologies

   Incident Management uses various tools and technologies, such as:
   1. Incident Ticketing Systems: Software applications to log, track, and manage incidents throughout their lifecycle.
   2. Knowledge Management Systems: Central repositories of known errors, workarounds, scripts, and solutions for efficient incident resolution.
   3. Communication and Collaboration Tools: Assist Incident Management for effective communication among support teams and stakeholders.
   4. Event Management Tools: Monitor the IT infrastructure, automatically alerting any state change that may cause service interruptions.

Problem Management

1. Definition and Objectives

   Problem Management focuses on identifying the root causes of incidents and addressing them proactively to prevent recurring incidents. Its objectives include reducing the impact of problems, identifying and resolving underlying issues, improving overall service stability, and authorising workarounds (ways to enhance productivity by implementing the full resolution).

2. Problem Lifecycle and Process Flow

   The Problem Management lifecycle typically involves the following stages:
   1. Problem Identification: Identification begins with the Service Desk linking each incident to a problem. The Service Desk creates a problem and relates the incident to the record if there is no record. The Problem Management team may add problems by identifying patterns and trends.
   2. Problem Logging: Recording essential details of the problem, including its impact and symptoms.
   3. Problem Categorisation and Prioritisation: Assessing the urgency and impact of the problem to prioritise its resolution effort. Priority changes with the number of incidents linked to the problem.
   4. Problem Investigation and Diagnosis: Analyzing the problem to identify its root cause and potential solutions. This documentation goes into another linked record called a Known Error. Several issues may relate to a single Known Error.
   5. Problem Resolution: Implementing permanent resolutions occurs through Change Enablement authorisation. Workarounds are proven temporary fixes to help users return to work while the problem is in resolution mode. The Service Desk applies workarounds to help users increase productivity until the availability of a permanent solution.
   6. Problem Closure: Confirm the successful resolution of the problem and document the details. Some issues may never be closed because of the expense.

3. Root Cause Analysis Techniques

   There are many root cause analysis techniques used in Problem Management, including:
   1. Ishikawa Diagram (Fishbone Diagram): Identifying potential causes by categorising them into different dimensions, such as people, processes, technology, etc.
   2. 5 Whys: Repeatedly asking "why" to uncover deeper causes behind the problem.
   3. Pareto Analysis: Prioritising potential causes based on their frequency and impact.
   4. Fault Tree Analysis: Analyzing the problem's causes and their relationships using a graphical representation.

4. Known Error Database

   A Known Error Database (KEDB) is a repository of problem documentation and known resolutions. It helps in efficient problem resolution by providing reference information and enabling quicker incident response.

5. Problem Management Tools and Technologies

   Tools and technologies supporting Problem Management include:
   1. Problem Management Systems: Software applications that assist in documenting, tracking, and managing problems, Known Errors, and their resolution.
   2. Knowledge Management Systems: Central repositories for capturing and sharing known errors, workarounds, and problem resolutions.
   3. Data Analysis Tools: With the emergence of big data and AI, these tools analyze large volumes of incident data, identifying trends and assisting in root cause analysis. The effectiveness of data analysis depends on the accuracy of the Incident Management records. Quality audits may Improve incident quality.
   4. Collaboration Platforms: These tools assist when multiple teams need effective collaboration and communication among Problem Management teams.

Change Enablement

1. Definition and Objectives

   Change Enablement (Change Management) encompasses the processes and procedures for controlling and managing IT services, systems, and infrastructure changes. Change Enablement ensures the matching of change types with the appropriate change authority, and its objectives include minimising service disruptions, assessing and managing risks, and ensuring that changes align with business requirements.

2. Change Types and Change Authorities

   Type	Definition	Responsibility
   Standard Change	Low risk, pre-authorised, well understood, and thoroughly documented.	Change Manager
   Normal Change	The change needs a risk assessment and authorisation. Change Enablement schedules all normal changes.	Change Advisory Board (CAB)
   Emergency Change	Must be implemented as soon as possible	Emergency Change Advisory Board (ECAB)

3. Change Lifecycle and Process Flow

   The Change Management lifecycle typically involves the following stages following the approved project management methodology:
   1. Change Request: A digital record to request permission to change an IT service or infrastructure configuration.
   2. Change Evaluation (Normal Change): Assessing the requested change's impact, risks, and benefits.
   3. Change Planning and Approval: Developing a change plan, obtaining necessary approvals, and scheduling the change window.
   4. Change Build and Test: Implementing the change and testing it in a controlled setting.
   5. Change Implementation: Executing the change during the approved change window.
   6. Change Review and Closure: Evaluating the success of the change, capturing lessons learned, and updating the documentation.

4. Change Advisory Board (CAB) and Change Models

   Change Advisory Board (CAB) is a group of stakeholders responsible for reviewing and approving Normal changes. They assess the impact of proposed changes, evaluate risks, and provide recommendations for change implementation. Change models are predefined templates or workflows for standard changes that have been pre-authorised and require minimal assessment and approval.

5. Risk Assessment and Impact Analysis

   Change Management involves assessing the risks associated with proposed changes and analyzing their potential impact on IT services and infrastructure. Such analysis helps prioritise changes, determine appropriate controls, and plan contingencies.

6. Change Management Tools and Technologies

   Many tools and technologies support Change Enablement, such as:
   1. Change Enablement Systems: Software applications facilitating change request tracking, evaluation, approval, scheduling, and documentation.
   2. Configuration Management Databases (CMDBs): The configuration system stores information about configuration items and their relationships, aiding in risk analysis and change planning.
   3. Workflow Automation Tools: Tools that automate and streamline change processes, ensuring adherence to defined project management workflows and approvals.
   4. Collaboration and Communication Tools: Platforms for efficient communication among change management teams, stakeholders, and CAB members.
   5. Change Schedule Tool: The ITIL Change Schedule defines future changes helping IT and users for planning purposes. It includes change details, such as the nature of the change, and the expected date, time, and duration of any service outages. The change schedule is for Normal changes only.

Service Level Management

1. Definition and Objectives

   Service Level Management defines, negotiates, and manages Service Level Agreements (SLAs) between the IT service provider and its customers. Its objectives include ensuring that IT services meet agreed-upon service levels, monitoring and reporting service performance, and driving continuous service improvement.

2. Service Level Agreements (SLAs) and Service Catalogs

   SLAs are formal agreements between the IT service provider and its customers, outlining the expected service levels, performance metrics, and responsibilities. Service Catalogs describe the IT services offered, including their features, dependencies, and service level targets. Every service defined in the Service Catalog must have an SLA.

3. Operational Level Agreements (OLA)

   OLAs are formal agreements between each IT functional team and the other teams they work with. Much like SLAs, OLAs define how functional groups should support each other in meeting the SLA's obligations.

4. Key Performance Indicators (KPIs) and Service Reporting

   Service Level Management relies on various KPIs and metrics to measure and report service performance. Common KPIs include service availability, incident response time, Service Desk response rate, and customer satisfaction. Service reporting involves regularly communicating service performance to stakeholders through reports, dashboards, and scorecards.

5. Service Improvement Plans (SIPs)

   Service Level Management creates Service Improvement Plans (SIPs) as part of the Continuous Service Improvement Practise. SIPS derives from service level performance analysis and customer feedback. SIPs identify areas for improvement, define action plans, and set targets for enhancing service quality and meeting evolving customer needs.

6. Service Level Management Tools and Technologies

   Tools and technologies supporting Service Level Management include:
   1. SLM Systems: Software applications for creating, tracking, and managing SLAs and service-level targets.

Configuration Management

1. Definition and Objectives

   Configuration Management maintains accurate and up-to-date information about IT services, infrastructure components, and their relationships. Practise objectives include ensuring the integrity and availability of configuration data, supporting other ITSM processes, and facilitating efficient change management.

2. Configuration Management Database (CMDB)

   A Configuration Management DataBase (CMDB) is a centralised repository of the Configuration Management System (CMS) that stores configuration data, including details about IT assets, infrastructure components, software, and their relationships. The CMS is a reliable information source for decision-making, change impact analysis, and incident/problem resolution. Configuration Management should only change items in the CMS with an approved Request for Change (RFC) to enhance accuracy.

3. Configuration Items (CIs) and Relationships

   Configuration Items (CIs) are an IT infrastructure's components that must be managed and tracked. Examples of CIs include servers, network devices, applications, databases, and user devices. Configuration Management focuses on establishing and maintaining relationships between CIs to understand their dependencies and impact.

4. Configuration Management Processes and Tools

   Configuration management tools help automate these processes and enable efficient tracking, version control, and reporting of configuration data. Discovery tools continually scan the infrastructure, ensuring that each item is authorised. The tool automatically opens an incident if not authorised.

IT Asset and Inventory Management

1. Definition and Objectives

   Asset and Inventory Management is closely related to Configuration Management, focusing on tracking and managing the physical and non-physical assets having a minimum monetary value. Configuration Management does not consider value, only that it contributes to the delivery of services. Asset Management includes hardware, software licenses, documentation, and optimising asset utilisation.

2. Practise Value

   IT Asset Management contributes value to organisations in the following ways:
   • Optimise the use of resources.
   • Support decision-making about the purchase, reuse, and retirement of assets.
   • Meet regulatory and contractual requirements.
   • Maximise value.
   • Control costs.
   • Manage risks.

Release Management

1. Definition and Objectives

   The objective of Release Management is to make accessible for use new and updated services and functionality, and a release is when a version of those, including Configuration Items (CIs) is released.

2. Release Planning and Scheduling

   Release Planning involves coordinating with Deployment Management to define a release's scope, objectives, and dependencies. It includes identifying release components, scheduling release windows, and coordinating with stakeholders.

3. Release Testing and Acceptance

   Before Deploying Management releases, they must pass thorough testing and acceptance procedures to ensure their quality and compatibility. Testing may involve functional testing, integration testing, User Acceptance Testing (UAT), and performance testing.

4. Release Management Tools and Technologies

   Tools and technologies supporting Release Management include:
   1. Release Management Systems: Software applications that aid in planning, tracking, and managing the release lifecycle, including release schedules, milestones, and dependencies.
   2. Version Control Systems: Tools that enable effective management and tracking of different versions and releases of software and configurations.
   3. Test Management Tools: Platforms for planning, executing, and managing the testing activities associated with releases.

Deployment Management

1. Definition and Objectives

   Deployment Management aims to move new or updated infrastructure environments, including hardware and software and related components to a production environment. Deployment Management, Release Management and Change Enablement work closely together. It takes the thoroughly tested release and ensures transitioning to the live environment with as little disruption to operations.

2. Release Planning

   Deployment Management works with the project team of Change Enablement, Release Ranagement, Project Management, and user groups to ensure optimal scheduling, user awareness, user training, completed documentation, written knowledge articles, and trained support teams to manage the new deployment. Early Life Support ensures coordination between all service teams before they are operationally responsible.

3. Early Life Support (ELS)

   ELS is a phrase that follows deploying a new or significantly changed IT service. The main objectives of ELS are to ensure a smooth transition from Deployment to live operations and to provide support and guidance during the initial stages of service operation. Critical objectives are:
   • Service stabilisation.
   • User support and training.
   • Knowledge transfer.
   • Performance monitoring and optimisation.
   • Incident management (service operations only take over after achieving a minimal level of disruption).
   • Feedback collection.
   • Documented continuous improvements.

ITSM implementation and governance

ITSM implementation lifecycle

1. Assessing Organisational Readiness

   Before implementing ITSM, assessing the organisation's readiness for change is imperative. The ITSM lifecycle involves evaluating factors such as the organisation's culture, resources, capabilities, and commitment to adopting all ITSM practises.

2. ITSM Tool Selection and Customisation

   Selecting the appropriate ITSM tool is essential for effective implementation. Organisations should evaluate various ITIL tools based on their functionality, scalability, integration capabilities, and alignment with the organisation's specific requirements. Customisation of the selected tool may be necessary to tailor it to the organisation's unique needs.

3. Process Design and Documentation

   ITSM implementation involves designing and documenting practises that align with ITIL or other relevant frameworks. Alignment includes defining process workflows, roles and responsibilities, escalation paths, and Key Performance Indicators (KPIs) for each ITSM practise.

4. Training and Communication Considerations

   Before selecting an integrated ITSM tool, the IT team should receive training in ITIL, tools, roles, and responsibilities within the new ITSM framework. Employ effective communication strategies to create awareness, gain buy-in from stakeholders, and manage expectations throughout the implementation process.

5. Leadership Team

   A robust IT leadership team starts with ITIL training of all leaders, especially the CIO and department heads. Another critical role assigned is an ITIL Service Manager — an expert in how all the parts work — led by a Continuous Improvement Manager and Practise managers. With 34 Practises designed to work together, knowing the risk of not adopting all Practises must be highly prioritised because it determines how long and what ROI and TCO you can expect.

6. Implementation Challenges and Success Factors

   ITSM implementation may face challenges such as resistance to change, lack of resources, inadequate executive support, or insufficient knowledge and skills. Success factors include strong leadership commitment, clear communication, employee engagement, ongoing support, and effective change management practises.

ITSM governance and continuous improvement

1. Service Measurement and Reporting

   ITSM governance involves defining and monitoring key service performance metrics and KPIs. Regular measurement and reporting enable organisations to assess the effectiveness and efficiency of IT services, identify areas for improvement, and demonstrate compliance with Service Level Agreements (SLAs). In addition, creating Operational Level Agreements (OLAs) at the beginning helps to define how service teams work together for a shared service management goal.

2. Service Reviews and Audits

   Service reviews and audits evaluate the quality and adherence of IT services and procedures to established standards and best practises. Organisations can perform them in-house or by external auditors to identify gaps, assess risks, and ensure compliance with regulatory requirements.

3. Continual Service Improvement (CSI)

   Continual Service Improvement (CSI) is a very important aspect of ITSM governance. It identifies and implements improvements to enhance IT services' quality, efficiency, and effectiveness. CSI initiatives are driven by analyzing data, conducting root cause analysis, and applying problem-solving techniques to drive iterative improvements. A key role is assigning a Practise owner, reporting directly to the CIO.
   Employ a helpful ITSM tool called Continuous Service Register (CSR) to capture all improvement suggestions in one spot, ready for discussion, evaluation, and implementation.

4. ITSM Maturity Models

   ITSM maturity models provide a structured approach to assess an organisation's maturity level in implementing ITSM processes. These models help organisations understand their current state, identify areas for improvement, and define a roadmap for progressing to higher levels of ITSM maturity.

5. ITSM Governance Frameworks (e.g., COBIT, ITIL)

   ITSM governance frameworks, such as COBIT (Control Objectives for Information and Related Technologies) and ITIL (Information Technology Infrastructure Library), provide guidance and best practises for effective IT Service Management. These frameworks offer comprehensive approaches to governance, risk management, and process improvement in ITSM.
