| Question | Answer |
| What is the purpose of Relative Estimation? | Relative Estimation is used to make future predictions based on past experiences, knowledge, complexity, size & uncertainty required to complete backlog items. |
| At what Horizons is Relative Estimation used? | ALL HORIZONS |
| What improves over time with Relative Estimation? | The ability to accurately estimate as new information is discovered about capabilities and capacity. |
| Story points are provided as a numeric value to each story using __________. Story point is a reflection of the amount of _______ needed to deliver the story. | 1. Fibonacci scale 2. effort |
| Describe 'Planning Poker' | A team review each of the backlog items or stories. Each team member chooses a number. If there is alignment within 1 degree of numbers, one of them is chosen and the team moves on. If there is wide variation in the numbers, the discussion continues to uncover new information to help. |
| Describe 'Silent Sizing' | The team prepares the backlog items on individual cards and line them up on a wall/table. Each team member selects a card and places it on the wall/table. This is repeated for all of the cards, creating a linear line, with the ‘smallest’ cards at one end and largest at the other. Breaking points are then identified to group similarly sized items. Fibonacci scale story point then assigned to each group. |
| STRENGTHS of Relative Estimation? | - Simple & reliable - Accuracy improves over time - Sizing approaches are very collaborative and likely to have a positive impact on teams |
| WEAKNESSES of Relative Estimation? | - As it is based on historical data, having to estimate a completely new item can be challenging & accuracy is questionable - Changes to team composition may impact team velocity & capabilities - Numbers provided are team specific - confusing for stakeholders? - Stakeholders may focus on outputs (time taken) rather than outcomes (value) |
