Except &quot;proper software engineering&quot; would mean whatever is being built simply never gets built.<p>In many cases it&#x27;s better to get somewhere quickly with excel then work out if &quot;proper software engineering&quot; is required than never get off the ground because engineering something is too difficult.<p>Think of excel like lego. Someone can quickly build something out of lego. Now if someone tried to build a cathedral from lego, you might suggest that they find an architect and do some proper house building, but without lego they would never have tried.<p>And chances are they&#x27;re not building a cathedral.
