Hierarchically organized list of all features identified from the modeling session walkthroughs and discussions.
Features are granular functions expressed in client-valued terms using this naming template:
<action> <result> <object>
For example, calculate the total of a sale, calculate the total quantity sold by a retail outlet for an item
description.
Features are granular in accordance with the rule that a feature will take no more than two weeks to complete, but not
so granular as to be at the level of getters and setters. Two weeks is an upper limit; most features take less than
this time. When a business activity step looks larger than two weeks, the step is broken into smaller steps that then
become features.
Each feature belongs to one and only one feature set (activity), and each feature set belongs to one and only one major
feature set (area) as show in next Figure:
