Agile Principles & the Agile Manifesto
Part of the Product Management Roadmap
In short
In 2001, a group of software people wrote four short lines that changed how most teams work. Knowing what they actually say helps you spot fake "agile" quickly.
A set of values prioritizing working software, customer collaboration, and responding to change over rigid upfront planning — the philosophy behind Scrum, Kanban and most modern PM workflows.

Think of it like this
The auto driver who reroutes
A bus follows its fixed route even if the road ahead is jammed. A good auto driver sees the jam, takes the side lane and still drops you on time. Agile teams plan, but they change course when reality changes.
Watch it happen
The four values: left side valued more
1/5The manifesto lists four pairs. Both sides matter, but the left side matters more.
The big ideas
What you need to know
Ship in small pieces
Deliver working software often, in weeks rather than months, so feedback arrives early.
Talk face to face
Direct conversation is the fastest way to share understanding inside a team.
Welcome change
Late changes are allowed if they help the customer. Short cycles make that affordable.
Not anti-planning
The manifesto values plans and docs. It just values the left side more.
Save yourself the pain
Common mistakes
Oops
Saying "we're agile, so we don't need documentation".
Do this instead
The manifesto says working software is valued more, not that docs are useless. Write what helps.
Oops
Calling any process with standups "agile".
Do this instead
Check the values: are you shipping often, talking to users and adapting?
Your mission
