Exercise:: Mapping Engineering Practices to Agile Principles

What are the necessary and sufficient engineering practices that an agile team needs to support the Agile Manifesto's 12 principles?

There is no one right answer - yet there are some very common patterns one sees when this exercise is repeated for multiple teams within an organization transitioning to agile software development.  From this analysis one could derive the set of core practices for your agile organization.

Exercise :: Mapping Engineering Principles to Agile Practices (PDF) by David Koontz

Facilitation Guide
Set up Print all material, one Agile principle per page (enlarge if you wish).
Hang the Agile Manifesto on the wall.
Hang the 12 Principles on the wall.
Hang the suggested list of Practices on the wall.

Have multiple colors of sticky notes & lots of pens/markers.

Introduce the Manifesto and the 12 principles
Discuss the Agile Manifesto - tell the history - describe what a process is and is not. Is “Agile” is a process?  Describe a philosophy - could it be that?

Distinguish between a Principle and a Practice
Switch to the Engineering Practices - describe a few of them - invite participants to read the list, to circle the ones which they currently do very well. 
Invite them to add to the list - debate which practices are redundant (ex: code review & pair programming).

If the group currently has real disciplined practices - use them to map to the principles - however if not don’t waste your time - just to the desired future state.

Dot-vote - each person pick three (2-5 is a nice range for this) engineering practices they wish to use in the future - the best practices to make us an Agile team.

Using those top voted practices (limit to 5 -8 practices to map), have people pair up and map one practice at a time to the 12 principles.  Decide if the engineering practice “supports” the principle - if so put the sticky on the paper - if weakly supporting - put the sticky below - if not at all then no sticky. Same pair do each principle. Use different colored stickies for different practices to create a nice Info-graphic when all done.
Be the example - select two participants and demo the first few principles for something like TDD.

Which principle is weakly supported by practices?
What practice would fill this gap?
Which practice supports the most of the Agile philosophy?
Does it work alone - if we just do that one practice - are we Agile?
What is the “neccessary and sufficient” set of practices for Agile?
Which practices should we embrase as a core set?
