Here we see how the Zachman rows maps to the POET rows.

POET recognises two things about the Architect Perspective (row 3) in Zachman:

¨      An Architect’s Perspective actually covers the Strategising to Initiating Transformation phases, utilising the Structural information from the Contextual to Logical levels, driven by the Enterprise Context.

¨      An Architect’s perspective also exists within all of these levels depending on whether the complexity of the work at each level warrants it.

POET recognises two things about the Engineer Perspective (row 4) in Zachman:

¨      An Engineer’s Perspective actually covers the Initiating to Transitioning Transformation phases, utilising the Structural information from the Logical to the Physical World levels, driven by the Conceptual level.

¨      An Engineer’s perspective also exists within all of these levels depending on whether the complexity of the work at each level warrants it.

Having said that, there is another way too look at it…

If you consider Zachman’s rows to be more like disciplines than a cascade of work (essentially take the word perspectives and apply it ruthlessly) then the Architect and Engineering rows are correct. If this is the case, then the order of the rows is irrelevant. Aka there is no meaning to one row being at the top and another row being further down.

There is an inference because the rows at the top are more likely to be done earlier and the rows at the bottom are more likely to be done later, but the Architect and Engineer rows (perspectives) could be applied at any time. In fact, the more I think about it, the more I think that the architect and engineer rows should not be rows but should be disciplines that could be utilised on any of the other perspectives.

This would mean that we need new names for the architect and Engineer perspectives. Designer and Builder sound like good ones to me. So, we end up with something like the graphic below.

So, what this diagram illustrates, is that we consider the Architects and Engineers “perspectives” more as disciplines rather than phases, while we consider the other perspectives, more as perspectives rather than disciplines, but those perspectives map one2one with Phases.

I feel we are getting further, but I also feel I have not found the most elegant description.

Questions to ponder...

Do you agree that Zachman’s Architect and Engineer rows are wrong?

If not, how would you map these things?
