Version 2
Section 4.2
"The Planning Horizon". This section explains that in agile
the level of detail increases as the work becomes more imminent. "Items to be delivered in the near future are described in great detail
while items to be delivered further out are described at a high level." This supports analyzing to a level of precision just enough for the next decision.

Version 2
Section 7.1.4
"Guidelines and Tools - Just In Time (JIT) Analysis and Elaboration". This guideline explicitly states
"In agile business analysis
requirements are elaborated to the details needed just before they are needed for implementation." This directly supports the concept of doing just enough analysis for the immediate next step.

Version 2
Section 3.2.5
"Avoid Waste". This principle
derived from lean thinking
emphasizes that any activity not adding value is waste. Creating overly detailed analysis far in advance of when it is needed is a form of waste
as the requirements may change. Analyzing just enough to make the next decision avoids this waste.
