You write "The communication paths between engineers increase exponentially as the team grows in size.", but in fact the total number of communication paths between n nodes is equal to n * (n-1) / 2, which is not an exponential growth, but an polynomial growth (quadratic to be exact), i.e. O(n^2).

Hi,
You write "The communication paths between engineers increase exponentially as the team grows in size.", but in fact the total number of communication paths between n nodes is equal to n * (n-1) / 2, which is not an exponential growth, but an polynomial growth (quadratic to be exact), i.e. O(n^2).
I learned so much reading this. Also thank you for the bibliography/works cited.
While diagonal Scaling is an interesting infrastructure scaling, the use of load testing and the small team size were eye-opening
This allows me to delve deeper into some of mentioned concepts
