Via Frank Patrick's Focused Performance Weblog, I found another blog called AgileManagement, wherein the author intends to cover "software development management, agile processes, the Theory of Constraints, Lean Software Development and Feature Driven Development".
From there came two links related to business analysis and requirements modelling:
- Business Rules Come First -- an excerpt from the book Principles of the Business Rule Approach
- BRCommunity.com -- billed as "the Internet's only vertical community for business rule professsionals" and home of Business Rules Journal
