ST Service V-model figure 4.21 and 4.30 confusing
ST Service V-model figure 4.21 p92 and 4.30 p124
"the confusion lies in the steps that have to be followed on the V model. My opinion is that it is down the left hand side and back up the right hand side. The confusion comes from the number on the picture. 1a on the left, 1b on the right, 2a on the left, 2b on the right... there is absoultely no text to explain the direction of travel and perhaps the authors assumed that everyone would automatically know.
However, by adding connecting arrows and the numbering system used all it has done has caused confusion and (sometimes heated) debate."
