Testing knowledge base

I like Agile methodolody and everytime I try to adapt some practices from this methodolody to testing.

On that time, it's Planning Poker technique.

Benefits of this technique: 
1. Estimation are wighted up
2. Everyone understand and know what timeline they will have
3. Common responsibility of made decision.

How to play:
Make group of estimators and a Moderator.

1. Each estimator gets a deck of cards
2. The moderator reads the description of task
3. Task are discussed by team. Open points to be clarified.
   
4. Estimators should select an estimate card and and place it face down on the table
5. After all estimates are in, the cards are flipped over
6. In the event that the estimates differ, the high and low estimation are discussed.
7. Group briefly debates any arguments. Then estimation session repeats until decision is done.
   
8. The moderator notes down the final estimate and the group continues with next task.

What are necessary things before meeting:

1. Work Breakdown Structure should be done.
2. Task should have as much information as possible.
