Explain the difference between a prescriptive and descriptive process model.

A prescriptive process model is one that outlines the steps that should be taken to achieve a particular goal. It is a kind of "how-to" guide, providing a detailed, step-by-step plan for achieving a specific outcome. This type of model is often used in business and project management to ensure that all necessary steps are taken and that nothing is overlooked.

On the other hand, a descriptive process model is one that describes how things actually happen. Instead of providing a plan for how things should be done, it provides an accurate representation of how things are currently done. This type of model is often used in research and analysis to understand existing processes and identify areas for improvement.

In summary, the main difference between a prescriptive and descriptive process model is that the former provides a plan for how things should be done, while the latter describes how things are currently done.
