Split into teams Go!

We will build paper airplanes

Iterations and re-planning of 2 min each

Line production conceptThe plane starts in an edge and ends in the otherThe engineering of production is a team decisionTeams are not allow to stock sheets for production

The product (airplanes) MUST conform with the scope defined

If a product doesn‘t pass the final quality review, it will not be accepted in the iteration

Products that are unfinished can be used in the next iteration to be complete

Every team will represent a factory (with logo)

The Air Force is planning to buy some new airplanes

The agent of the Air Force (me) contacted your factories to check for your proposals

I want to know how many airplanes you can deliver in TWO minutes

Since I am very impatient, you have ONE minute to discuss and inform the number of airplanes you produce in a TWO minute iteration

Start!

The Air Force liked the estimates and will open a competition

You will have TWO minutes to produce a prototype. The scope is:

Must have 12 windowsMust have a fly cabinMust have the logotype of your company on

both wingsMust fly across table (~2 meters)

The prototype will be shown to the group.

The winner :Deliver more airplanesDeliver the quantity as promised

4 iterations of 2 minutes to produce the planes

2 minutes at the end of each iteration to check and act about your production line, to increase productivity.

You will give the estimates in the beginning of each iteration.

Client (me)Gives the scope and approves each

Team leaderThe leader can‘t build the airplanes. The leader should take care of the team,

help to with the process, remove impediments and get the material.

Did you get what the client wanted in the beginning?

Did the prototype help? Why?

Did the estimates got better with time? Why?

Was the concept of inspect/adapt useful? What was the most useful?

Did team leader help? How? Who made decisions?

What is better for you and the client:Deliver all the airplanes in 10 minutes?Deliver a % of airplanes each 2 minutes?Re

Define “what” to do

Sprint planning

1. Team participates while PO’s available2. Team breaks items into tasks to form
