This video introduces the agile estimation approach of relative estimation and its advantages over absolute unit estimation with a simple example. It explains why estimation in Fibonacci or exponential series is better than estimation in a linear series.
- Estimates are an essential starting point for any project…and agile teams rely on them as well,…but agile estimates are not for coding…and unit testing alone.…Agile estimation is all about refining…product backlog items into smaller implementable items…and then estimating what it takes…to convert that backlog item into a done item.…Agile estimates are provided…by the development team members,…they are not imposed by the managers.…
The type of estimation traditionally used…by product managers is absolute unit estimation.…This type of estimation uses the number…of time units like hours, days, or weeks.…However, a new and more effective estimation approach…has gained popularity in the agile world,…estimation in relative units.…Absolute unit estimation can vary significantly…based on individual skills and experience.…
If you ask two developers…with significantly different skills…and experience levels to estimate the same item,…their estimates will likely vary by a wide margin.…Relative estimation leads to consensus much quicker…
