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:

Lean OK is an approach that would be most helpful for an organization that wants to become more efficient by reducing the amount of unnecessary work they do. Lean OK is a combination of Lean and OKR (Objectives and Key Results), which are two complementary methodologies that aim to optimize value creation and eliminate waste. Lean is a philosophy and a set of principles and practices that focus on delivering value to customers and stakeholders, minimizing waste and inefficiencies, and continuously improving processes and products. OKR is a goal-setting and management framework that helps organizations align their objectives with their vision and strategy, communicate and track their progress, and measure their outcomes and impact. By using Lean OK, an organization can define clear and ambitious objectives that are aligned with customer needs and organizational goals, and set measurable and achievable key results that indicate how well the objectives are met. Lean OK also helps the organization to identify and eliminate any activities or processes that do not contribute to value creation or goal achievement, and to prioritize and optimize the ones that do. Lean OK enables the organization to become more efficient, effective, agile, and customer-centric. References:
