Large batch sizes of work are considered a barrier to high performance in Lean and Agile because they increase the amount of work in progress (WIP), which leads to longer cycle times, higher variability, lower quality, and reduced feedback and learning. Large batches also increase the risk of waste, rework, and delays, as well as the complexity and uncertainty of the work. Lean and Agile advocate for reducing batch sizes and limiting WIP, which enables faster flow, shorter feedback loops, higher quality, and more value delivery. Some of the practices that help reduce batch sizes and limit WIP are:

• Pulling versus pushing work, which means that work is initiated only when there is a demand and capacity for it, rather than being assigned or scheduled in advance.
• Making work visible, which means that the status and progress of work are transparent and accessible to all stakeholders, using tools such as Kanban boards, burn-down charts, and dashboards.
• Limiting work-in-progress, which means that the number of work items in each stage of the workflow is restricted, based on the available resources and throughput, to prevent bottlenecks and overloading. References: 

A digital organization is an organization that leverages digital technology to create value for its customers, employees, and other stakeholders. A digital organization is not just an organization that uses IT to support its operational processes, or an organization that has undergone an IT transformation, or an organization that uses IT to improve its ‘service desk’ practice. These are examples of IT-enabled organizations, but not necessarily digital organizations. A digital organization is an organization that uses IT to change its strategic direction, to create new business models, to innovate and differentiate itself from competitors, and to deliver value faster and more effectively. A digital organization is an organization that adopts a digital mindset, culture, andcapabilities to thrive in the digital era. References:https://www.axelos.com/resource-hub/blog/itil-4-leader-dits-guide-for-digital-transformation

Onboarding is one of the six activities in the service value chain, which is the set of interconnected activities that an organization performs to deliver a valuable product or service to its consumers and other stakeholders1. Onboarding involves providing the consumer with the agreed service and ensuring that they can use it as intended1. This includes building awareness of the new consumer, such as informing them about theservice features, benefits, and costs, as well as ensuring resources are prepared for service provision, such as allocating staff, equipment, and facilities2. Negotiating service targets with customers is part of the engage activity, which involves understanding the needs and expectations of the stakeholders and establishing agreements on how to meet them1. Designing the service components and infrastructure is part of the design and transition activity, which involves ensuring that products and services continually meet stakeholder expectations for quality, costs, and time to market1. References:

Customer orientation is an approach to business that focuses on assisting customers in achieving their goals, as opposed to adopting a sales oriented methodology12. It involves understanding the needs, expectations, and preferences of the customers and delivering value that meets or exceeds them. Customer orientation also implies adapting to the feedback and behavior of the customers and tailoring the service accordingly. Therefore, when a service support agent adjusts support actions following a call from a frustrated user, they are demonstrating customer orientation, as they are trying to resolve the user’s issue in a way that suits their emotional state and satisfaction level. Customer orientation is one of the key concepts in ITIL 4, as it helps to create value co-creation and drive stakeholder value34. It is also aligned with the ITIL guiding principles of focus on value, collaborate and promote visibility, and keep it simple and practical34. References:

The best way for the organization to collect the information needed to address the complaints is to collect customer experience and service level metrics. Customerexperience metrics are measures of how customers perceive the quality and value of the service and the interactions they have with the service provider. Service level metrics are measures of how well the service meets the agreed requirements and expectations of the customers and users. By collecting both types of metrics, the organization can identify the gaps and issues in the service delivery and the customer journey, and take actions to improve them. Some examples of customer experience metrics are customer satisfaction, net promoter score, customer effort score, and customer loyalty. Some examples of service level metrics are availability, reliability, performance, and incident resolution time. References:https://www.axelos.com/resource-hub/blog/itil-4-leads-to-value

The correct answer is B. The service value chain because it is the core component of the ITIL 4 service management framework that describes how an organization orchestrates its IT capabilities to achieve its strategic objectives. The service value chain is an operating model that covers all the key activities to flexibly manage products and services1. It consists of six interconnected value chain activities: plan, improve, engage, design and transition, obtain/build, and deliver and support2.

Option A is not correct because the four dimensions of service management are not an operating model, but rather a holistic perspective that should be considered for the effective and efficient facilitation of value co-creation2. The four dimensions are: organizations and people, information and technology, partners and suppliers, and value streams and processes2.

Option C is not correct because the ITIL guiding principles are not an operating model, but rather a set of recommendations that can guide an organization in all circumstances, regardless of changes in its goals, strategies, type of work, or management structure2. The ITIL guiding principles are: focus on value, start where youare, progress iteratively with feedback, collaborate and promote visibility, think and work holistically, keep it simple and practical, and optimize and automate2.

Option D is not correct because continual improvement is not an operating model, but rather a recurring organizational activity performed at all levels to ensure that an organization’s performance continually meets stakeholders’ expectations2. Continual improvement is based on the continual improvement model, which consists of four steps: what is the vision, where are we now, where do we want to be, and how do we get there2.

The value chain activity that ensures that products and services continually meet stakeholder expectations for quality, costs and time to market is design and transition. This activity involves the following steps12:

• Defining the requirements and specifications of the products and services based on the demand and feedback from the customers and other stakeholders.
• Designing the products and services according to the requirements and specifications, as well as the best practices and standards of the organization and the industry.
• Developing and testing the products and services to ensure that they meet the quality criteria and the expected outcomes.
• Deploying and releasing the products and services to the customers and users, ensuring that they are ready for use and operation.
• Validating and evaluating the products and services to ensure that they deliver the intended value and meet the stakeholder expectations.
• Transitioning the products and services from the development stage to the operational stage, ensuring that they are integrated with the existing processes, systems and resources of the organization. References: 1: ITIL 4 Create, Deliver and Support, AXELOS, 2019, p. 23-24 2: Value Chain Activity: Design & Transition - Altervista, 3
