The big companies each maintain their own style for text, block diagrams, timing diagrams, tabular data, and mathematical formulas across thousands of documents with numerous authors. What kind of tech are they using to enforce the style consistencies? Custom document build system? In-house SVG diagram generators? Are these kinds of tools for sale anywhere? Or would you need a print media team to polish the engineer's output according to a rigid style guide?
What kind of system could a small team adopt to be able to generate docs and graphics with this kind of brand consistency?

LaTeX provides better typesetting defaults than Microsoft word, but it fails as a publishing tool. It's trivial to typeset the text, but if you try to emulate the layout of a reference datasheet it's an uphill battle to layout graphics where you want them. No doubt LaTeX could be made to work but is it the tool that established documentation teams are reaching for?
