Objective:
Familiarize with scenario-based approach using the UCS, and practice hierarchical task analysis as a requirements analysis method.
Instructions:
Review the Garden.com example in the UCS (Usability case library), especially the Requirements Analysis section. Garden.com was a highly-acclaimed web site that was later consumed by established competitor Burpee.
Based on what you learn from their requirements analysis, develop a Hierarchical Task Analysis (HTA) for the task of planning a garden. This should include just the planning stage, not the shopping or planting stages. Use the existing requirements analysis to acquire steps that you would not likely have known (such as considering animals!). Also embellish your HTA with your own knowledge to make it thorough.
There is no single 'right' answer for this exercise, although we will be looking to see that you have created a complete analysis. Remember to include decision or control rules where there are multiple steps. We will be checking to see that you understand hierarchical decomposition, and that you have made an effort to carefully research and think about the garden planning task.
Hand in:
Your HTA hierarchy hard-copy. You may either hand-draw (neatly) the hierarchy or use a graphical editor of some sort. If the graph does not fit on a single page, be sure to indicate how it connects across pages.
