About this document
Purpose. This document defines given CT2 component from the business prospective. It is completed by Analysis Team and serves as a blueprint for Design Team.
Completeness and scope. It should have enough details for Design Team to complete its work with minimal additional input. But it should not have too many implementation details because this would limit choices and as a result better design might not be considered (better in terms of time it takes to implement or usability). See example below.
- CT2 has 3 similar in functionality components: ICom, Com, Query. If Analysis Team did not originally mandate that they are absolutely different then Design Team might have combine then and this would result in significant savings in terms of programming, testing and support man-hours.
Sections. In general this document should have several sections - see below.

It is very important to understand what are we trying to acomplish with this component / feature and what we are not. Sometimes of course it is obvious. But in many cases users have different ideas about this. That is why it should be clearly defined. See example below.
- EQuery component's main purpose is to provide a quick way for jaguar user to ask question Operator of last change about particular CT record. This works best when user has this record open because with one click of a mouse she can reach EQuery tab and start typing her question. It takes just another click ('Submit' button) to send request. Additional purpose / benefit is that all questions are being logged and always displayed on the EQuery tab.
