Comprehensive and Detailed Explanation From Exact Extract:
ITIL 4 defines four dimensions of service management that are critical for the effective and efficient co-creation of value:
Organizations and people
Information and technology
Partners and suppliers
Value streams and processes
The “Organizations and people” dimension addresses:
Organizational structure – how the organization is arranged.
Roles and responsibilities – who does what and who is accountable.
Systems of authority and communication – how decisions are made and communicated.
Culture and competencies – behaviors, skills, and capabilities of people involved in service management.
Because this dimension specifically covers roles, responsibilities, and systems of authority, the correct answer is A. Organizations and people.
The other dimensions focus on different aspects:
Information and technology – data, information, and technological solutions used in service management.
Partners and suppliers – relationships and agreements with third parties that support service delivery.
Value streams and processes – how activities and processes are organized to create and deliver value.
