Purpose of Estimation

Work estimation is essential for finishing a project within the desired schedule while helping the team to measure the success rate. Estimates may also help in making weighty decisions and creating a shared understanding of the requirements and solutions. Here is a list of estimation techniques to choose from:

  1. Planning Poker: Widely used across the globe, ‘planning poker’ is based on an agreement from the team on the points being assigned to the product backlog item (PBI). It ensures that each individual in the team participates and shares an opinion for the project or task in-hand.
  2. T-Shirt Sizes: This technique is for estimating the backlog of large items. The concept is accurately grouping items of the same size together in a bin. All the bins will be given labels matching to the common size of the T-Shirts in small, medium, large and XL, etc.
  3. The Bucket System: This one is similar but way faster than planning poker and a decent substitute for estimating a lot of items with a big group of participants. A range of buckets, usually made of brown paper are placed with values from 0-100, each containing a sticky note where processed items are kept. The group of participants has to estimate the items by placing them in these buckets.
  4. Large/Uncertain/Small: The methodology categorizes items as per their size and certainty. While populating the extreme categories, a group of participants can discuss the intricate items. The technique is suitable for small groups with comparable items.
  5. Dot Voting: This technique is best for a small set of items, coined from decision-making and apt for estimation. Each participant gets a small number of stickers of dots to choose or vote for one item. More the dots, bigger is the size. The method is simple and fast enough to assess a small number of stories up to 8-10.
