Imagine building a house..
without any architectural plans
with only general sketches as to how it’s supposed to look, or only detailed diagrams for wiring, plumbing, etc.
with each subcontractor doing whatever they thought best, without consulting with the owner or other contractors
with no specialized functions for the rooms (e.g., every room has its own little stove, bed, bathtub…)
where the house had to be torn down to remodel one room S.O.P. for building information systems in public health.
