2 Estimating task duration estimation task duration is a lengthy process that takes time, especially for a long-term project. Due to this, there is a need to involve the core project team to estimate the duration and use different project management methodologies to help estimate task duration. Six task duration techniques were identified in the text, but the one that produced the best estimates was the tree point technique (Wysocki, 2011). This is the best way to estimate task duration, especially with historical data. The technique is essential to allow teams to plan critical activities when it has historical data from more than a project for the same activity. The tree point technique is proper and helps increase the accuracy of cost and time estimates. It involves using three estimates to give a more accurate task duration estimate. These estimates include optimistic, which is the best-case scenario, the most probable, which is the most likely scenario and pessimistic, the worst-case scenario. (Wysocki, 2011). All these possible estimates are then combined to give the overall estimate. In addition, the technique is most useful for task duration as it considers the potential for uncertainty in the task and the potential for the task to take longer or less time than expected. Also, I think this is the best technique to provide the best estimates as it helps in reducing risks as it offers more accurate estimates hence helps in mitigating the potential risks or failures, and it reduces the likelihood of an overly optimistic estimate Various techniques for gathering estimates in Agile include random distribution; this technique entails placing items in order from low to high. Each person must take a turn when choosing to move an item up or down one spot. The other technique is through planning poker; this process involves the ability of team members to use their expertise to estimate how long the task will take and how much effort it will require (Vyas et al., 2018). The technique is best for a
3 small number of items as it gets unanimous buy-in quickly. The other technique used in Agile is Affinity grouping; this estimation approach works by having team members group similar items. Thus if the tasks seem related in scope, they are put together until one has a clear set of groups. Furthermore, agile teams could also use three-point estimates in gathering their estimates. This technique would be helpful as it provides them with three values, including the most likely estimate, optimistic and pessimistic; thus, the team members can obtain the most accurate estimate by adding up the values and dividing by three.
