Agile Estimation Techniques - What NOT To Do...
- Relative estimation is a technique that involves assigning a relative size to each item in the product backlog. This approach does not rely on specific units of measurement, such as hours or days, but instead compares each item to others in terms of relative complexity, effort, or risk. The most commonly used method for relative estimation is called the Fibonacci sequence, which assigns a sequence of numbers to represent the relative size of each item.
- Planning poker is a game-like technique that involves the entire team in estimating the relative size of each item in the product backlog. In planning poker, each team member is given a set of cards with numbers that represent the relative size of each item. The team then discusses the item and each member chooses a card that represents their estimate. The estimates are then shared, and any discrepancies are discussed until a consensus is reached.
- Wideband Delphi is a technique that involves a facilitator who solicits anonymous estimates from team members, compiles them, and shares them with the group for discussion. This approach helps to prevent bias and encourages more honest and accurate estimates. The facilitator then guides the team in a discussion to reach a consensus estimate for each item.
DON'T USE A NUMBER!!
