This module was dealing with tasks and analysis that make up a process and various ways to categorize these tasks. When designing or evaluating an interface its a good idea to to create a list of the tasks that are needed to work with the interface and organize them accordingly and identify any sub tasks or sub tasks of sub tasks in order to show the hierarchy and give a better visualization and understanding of how these tasks work within the interface. This type of mapping will give you a better understanding of how the interface works and how to interact with it and allows you to look at each task more specifically (easier to go into details when tasks are written down as apposed to trying and do them off memory).
Overall i would say this was a great module to help understand the importance of proper design and how users interact with the design. It makes designing a lot easier when things are written down in order to go through things one by one instead of just going off memory and with a proper task analysis it can lead to better designs in the future for upgrades to that interface.
