I believe business analysis should be effortless. I've learned over the years what works, what doesn't work, and what made things easier vs. harder.
If you can get at the same information, provide the same level of concise, clear and complete requirements with less effort, then why wouldn't you do that?
My unique method of analysis will help you understand exactly what's necessary, what can be left out and how to elicit, document and share information in a way that allows the entire project team to avoid roadblocks and be successful.
