- 2. people of different nationalities REQUIREMENTS Let us start with passengers at an airport . People of different nationalities, locations, some possibly infected, waiting to board. Akin to requirements for new features.

- 4. people of different nationalities REQUIREMENTS screen ENSURE CLARITY We screen and allow them to board only if they are found to be fit for travel. Much like ensuring clarity of requirements before we commence building the feature
- 5. people of different nationalities REQUIREMENTS screen ENSURE CLARITY When they land at destination, screen them again , suggest self quarantine or isolate if infected. Much like ensuring clarity of requirements before we commence building the feature.
- 6. SELFQUARANTINE ENSUREBASICHEALTH screen people of different nationalities REQUIREMENTS screen ENSURE CLARITY passengers NEW CODE When they land at destination, screen them again, suggest self quarantine or isolate if infected. Ensuring that basic health of new code is good before it is integrated.

Much like ensuring that system is stable when changes in code or environment happen.

In the case of software, it is - make code defensive, assess code health constantly and be robust.
