Correct option is C
Organizational development (OD) is a field of research, theory, and practice dedicated to expanding the knowledge and effectiveness of people to accomplish more successful organizational change and performance. Let's evaluate the characteristics listed:
It is a long-term approach: OD typically involves long-term strategies and plans to improve the organization over time.
It utilises systems thinking: OD often employs systems thinking to understand and improve the organization as a whole, rather than focusing on individual parts in isolation.
It is an unplanned change: This is NOT a characteristic of organizational development. OD is typically a planned, systematic approach to change, involving deliberate interventions and strategies.
It is a dynamic process: OD is indeed a dynamic process, continually adapting and evolving as the organization changes.
Therefore, the correct answer is It is an unplanned change.
