Organizational structure is the concept that is primarily concerned with multiple teams moving to a cross-functional way of working. Cross-functional teams are teams that consist of members from different functional areas or domains, such as development, testing, operations, marketing, etc. Cross-functional teams can help organizations achieve better collaboration, innovation, and customer satisfaction, as well as faster delivery and feedback. However, cross-functional teams also require changes in the organizational structure, such as breaking down silos, flattening hierarchies, and empowering teams to self-organize and make decisions. ITIL 4 encourages an integrated approach that combines best practices across all ways of working, such as Agile, DevOps, and Lean. These methodologies keep rules simple, allowing teams to adapt based on the situation, focus on good outcomes for the customer, and learn from failure. ITIL 4 also explores the four main types of organizational structures: functional, divisional, matrix, and flat. Each type has its own advantages and disadvantages, and organizations can choose the best fit for their context and goals. References:
