When the requirements are agreed upon and the technology is well understood (good examples of this categories are building a house or a bridge) the project falls under ‘Simple’ region in the Stacey’s matrix (see the picture below). In these scenarios waterfall approach will work just fine.

Process Models

However, in reality most of the projects fall under ‘complicated’ or ‘Complex’ region. In these cases, rather than laying out elaborate plans that you know will change, it is often better that you create a more fluid options. Try a little, inspect the results, and adapt the next steps based on the lessons learnt in previous cycles (sprints). Indeed, this is exactly what’s known as the empirical process model.

    Can I please get some help on how to create process model framework in an agile environment? I work in an insurance company and I have been assigned this task but I am having some difficulties.
