The CSI Model diagram on pages 15 (fig 2.3) and 30 (fig 3.2) both start with "What Is The Vision", followed by "Where Are We Now".
Page 163 of the same book has fig 8.4 also described as the CSI Model but without "What Is The Vision" step, starting instead with "Where Are We Now".
Clarification/justification required urgently as an exam question in V3 Foundation hinges on an understanding of what is the first step of the CSI Model.
