OD is about improving your organisation's overall effectiveness by carefully balancing the intricacies of people, process & performances. In practice, as every company is different, the work required will be different. Every individual has different stories and every company as a collective of individuals have a collective story that makes it culture. Where it works, we celebrate, where it doesn't we calibrate and change to become more effective.
At its heart, organisation development is about navigating changes to improve effectiveness by working in partnership across a whole system,
where change is considered as any disruption of a repeated pattern of thinking, feeling or behaviour.
