Manager vs Leader

Today I read a article and below statement is very interesting. Managers do things right, and leaders do the right thing. Then a manager who has a leadership will do the right things right. It reminds me a concept which a Chinese guy "Sun Tzu" said 2000 years ago in "The Art of War": a Strategist is making sure they are doing the right thing, and a Tactician is making sure the army is doing the thing right.

Manager manage the system, not the people

Here is the article.

Manager should create a system which:

1. People can do their job efficient.
2. People can get and give feedback.
3. People can grow.

Agile vs Lean

The 4 principles of Lean Development are:

-Add Nothing But Value (Eliminate Waste)
-Center On The People Who Add Value
-Flow Value From Demand
-Optimize Across Organizations

The Agile Manifesto says:

-Individuals and interactions over processes and tools
-Working software over comprehensive documentation
-Customer collaboration over contract negotiation
-Responding to change over following a plan
