- Team had to estimate items using a diff. technique.
- Each team got a set of cards with items written on them.
- Each team got the same items so we could compare between teams at the end.
- When each team finished estimating, the facilitator wrote results per team in a flip chart/white board, and start the discussion about the technique.
- The facilitator shared correct answers once each team has completed each exercise.
- A general discussion is hold about all techniques and the team decides where we go from here
DescriptionThe items to be estimated are country area. Remember that this technique is used for relative estimation
Instructions- Use Spain as your reference point (Value assigned to Spain Area is 3)- Each team have to estimate the area of each country(item) - Each team discuss about the item to get shared understanding, then each person chooses a card
from their set that they think is the closes fit. - Everyone displays their cards at the same time (avoid influencing other between each other). - People discuss the outliers, usually the highest and lowest numbers to see of the people who
selected them, had a different understanding to everyone else.- After discussion, people re-vote taking in consideration anything uncovered in the discussion.- Once everyone converges on a number that is selected as the estimate.- If convergence is not reached by the third vote, then the team would take the highest number or
majority number.Special note- To be able to compare each estimation technique, all teams should try their best to get results as soon as they can.
DescriptionThe items to be estimated are cars volume. Remember that this technique is used for relative estimation
Instructions- Lay out one set of planning poker cards so that you have all the numbers.- Agree on a reference story, and place it next to the reference point. In this case put the card
“Convertible” next to the Planning poker card identified with the number “3”.- Give the stack of story cards to the first person in the team.- Each person has a turn where you can either:
- take a new car from the stack of story cards and place it where you think it fits, or- Move a card already on the table to a new spot if you don’t agree with it.- Note: You must always move a card if you don’t agree with the estimate rather than playing a new one- Note2: If you play a new card it means you are happy with every card on the table.
- After your turn you hand the cards to the next person.- If you do a full circuit of the team and one card has been moved each time, then you discuss it
before continuing.- Note: People could explain why they are placing a card at a certain number, but remember,
