In today's dynamic world, developing sustainable capacities of organizations and institutions paradoxically means embracing change. To stay at the forefront, organizations not only need to adapt to external shifts but also nurture an internal capacity for change. In this course, participants familiarise with the multifaceted aspects of organizational development and change management, offering participants a range of skills and essential tools for systemic organizational diagnostics of capacities, strategic formulation of capacity development interventions, and agile yet effective change management and communication planning. Change is not a simple project journey. It involves a holistic capacity-building or adaptation effort, requiring alignment at the individual, group, and organizational levels, and shaping the organisation's environment to favour and sustain change. This course enables participants to acquire the knowledge and strategies needed to understand and navigate these dimensions. From conducting a systemic diagnostic of organisations, mapping relationships between actors to building strong teams and coalitions. Through the course, participants will gain a holistic understanding of organizational development and the change process. Furthermore, they will explore the nuances of creating impactful theories of change, designing capacity development interventions, and facilitating transformative organizational changes. Beyond theory, the course emphasizes practical application, bringing participants to immerse themselves in real organizational contexts. They will be challenged to work on their own case studies and change management plans, ensuring a hands-on learning experience.
