22. No matter how well we
ideate, create, test, surround & provide
the entire product.
$#!t happens
Need to 'Monitor' every important aspect of
product and product ambience.
Place 'Alert' on events, that you can wiki-fy on
how to handle.

24. Softwares don't breath on Developer nodes.
They are born there.
Softwares live in varied environments like
QA/Staging/Production.
To understand how our product works, we
need to notice its activities on environments.
Log & Analyze

● PaaS (no system level tasks) Platform
● IaaS (no physical maintenance) Infras.
● NaaS (seriously, you Dinosaurus) Null

the more components to interact;
hence more to scale, monitor, log and secure...

32. Lean
● Eliminate Waste like unnecessary code & functionality, unclear
requirements, less testing, bureaucracy, slow communication
● Amplify Learning instead of adding to documentation or planning, try &
learn
● Decide as late as possible until they can be made on facts not
assumptions. Set-based development flow allows better solutions.
● Deliver as fast as possible, without speed decisions can't be delayed.
● Empower the team, find capable people and let them use their capability.
Enable their access to customer.
● Build integrity in product quality, keep it flexible, maintainable, efficient &
responsive. Solve requirements simultaneously as the information flows in both
direction, not sequentially.
● See the whole... larger the system, the more organizations &/or teams
involved, greater the importance of having well defined relationship. A part of
strong team is much more beneficial than minimum interaction departments.
