The organisational design is more than simply your organisational structure. It's about having work activities and processes clear at every level of your organisation, with a strong tie to company strategy. The organisation structure is only one of the many elements of an operating model and is not necessarily the most effective lever of change. A more holistic approach enables an operating model to be aligned with the business strategy, which in turn will drive the achievement of your business outcomes.
Being clear on what's changing is critical - we call it defining the Target Operating Model
The Target Operating Model can be specific to the industry and the organisation itself. However, it often includes Governance, Metrics, People, Culture, Structure (see example below).
