This document discusses coding guidelines for a team. It notes that software bugs cost the US economy $1.1 trillion in 2016, up from $59.5 billion in 2002, and fixing bugs gets more expensive the later in the development process they are found. The document provides an onboarding checklist and outlines different types of coding standards like naming conventions, formatting style, exceptions, logs, database rules, and security specifications. It includes a link to the team's coding guidelines on GitHub.

3. Financial Cost of Software Bugs
● 2002: Software bugs cost the United States economy approximately
$59.5 Billion
● 2016: Software bugs cost the United States economy approximately
$1.1 Trillion (~20x)
● As a bug makes its way through the design phase, implementation,
integration testing, customer beta test and finally post production
release, it gets more and more expensive.
● The Systems Sciences Institute at IBM has reported that the cost to fix
an error found after product release was four to five times as much as
one uncovered during design, and up to 100 times more than one
identified in the maintenance phase.
