The docs tab now contains a document that describes a proposed approach to the design of the Opportunities database.
Basically, the Opps DB will consist of Opportunities documents to which child "Task" documents can be related. Comments can be posted as responses to either Opportunities or Tasks. Comment docs allow threaded discussions to be associated with any project or task.
This would work very much like project management software, and the same database could be used to track projects as well as or instead of sales methodologies. "Opportunities" and "Projects" can be thought of interchangeably, the only real difference being that opportunities are associated with sales, and therefore any schedule information is decidedly nebulous as opposed to a project. A project's "milestones" are an opportunity's "targets".
A fourth form, Methodology, would be used to create documents that define various methodologies. You could assign a methodology to any particular "Opportunity", which would then create the tasks (WBS) associated with the Opportunity to the methodology.
