-
measurable (it will include numerical/quantitative data, for example, dimensions, tolerances) ​
-
justified (include reasoning) ​
-
approved by users and stakeholders
It should include:
-
A formal assembly drawing
-
working drawings for each part/ component
-
material information (including costs)
-
