Final answer:
The effort estimation technique suitable for a Product Owner who wants to achieve consensus and include the Fibonacci sequence in their Backlog estimates is Planning Poker.
Step-by-step explanation:
If a Product Owner wishes to add estimates to their Backlog with an emphasis on consensus and the use of the Fibonacci sequence, the appropriate effort estimation technique to use is Planning Poker™. In Planning Poker, team members are given cards with Fibonacci numbers which they use to vote on the effort they believe is required for each Backlog item. This process encourages individual consideration followed by group discussion to achieve consensus on the estimates and leverage collective wisdom. It is considered a gamified approach that balances out the extremes and helps the team converge on a realistic effort estimation.
To incorporate the Fibonacci sequence and reach a consensus on effort estimation for a small number of items in your backlog as a Product Owner, you should use the Planning Poker™ technique. Planning Poker™ is a collaborative and gamified approach where team members use a deck of cards with Fibonacci sequence numbers to independently estimate the effort required for each item. They then discuss their estimates and aim to reach a consensus through discussion and re-estimation.
