Operational management is a crucial aspect of any business, as it helps ensure that the organisation’s day-to-day operations run smoothly and efficiently. One of the key tools used in operational management is the use of models and approaches. These models and approaches can be used to improve performance, reduce costs, and increase overall effectiveness. Some of the most common operational management models include the Four Dimensions of Operations, the Transformation Process Model, the Lean Model, the Six Sigma Model, the Theory of Constraints, Total Quality Management, Business Process Reengineering, the Agile Model, the Resource-Based View Model, and Operations Strategy Model. Understanding and using these models can greatly benefit any organisation. In this topic, we will look closely at some of these operational management models and how they can be applied in the real world.
