It is 1887, you are Monsieur Gustave Eiffel and you won the challenge to build the biggest structure made out of steal in the world, at that time. There was enough steel, enough workers, enough money and some time left to do the unthinkable:  a 300 high, metal tower in the middle of Paris, at the shores of the river Seine.

Everyone at that time was able to plan and calculate structures, fulfill requirements, make static calculalions et cetera. Many bridges and other buildings have been planned and assembled piece by piece, produced upfront in factories and shipped to the constrcution site, ready to be installed.

But how do you built such a singular, state-of-the-art but experimental construction? Monsieur Eiffel needed a Continiuous Integration and Continuous Delivery process to built it.

Well, he and his crew concieved a shaffolding structure, that dynamically supported the assembly of heavy steel components 100m above ground. So they engineered the system to build the tower as well as the tower itself. 

The bottom line of this story is: built your CI&CD first, then your product. No matter how good your product is, if you cannot build it nor ship it, it is worthless. I embrace this strategy and priorize a working CI and CD over new features.
