For business change to be successful, what must it be aligned with?

Successful business change must always be aligned with the strategy of the organisation. The primary purpose of a business change initiative is to achieve a specific business objective, and these objectives are derived directly from the organisation's overall strategy. If a proposed change, whether it's a new system, a process overhaul, or an organisational restructuring, does not support the strategic goals (such as increasing market share, improving efficiency, or enhancing customer satisfaction), it is unlikely to be approved or to deliver true value. The Business Analysis approach, particularly in the initial stages of a project, focuses heavily on understanding the strategic context and ensuring that the needs being addressed are strategic needs. This alignment is crucial for the Business Case to be justifiable and for the final solution to be judged as successful, as success is ultimately measured by the achievement of strategic goals.
