Disadvantages of Relative-size Estimation
- Unnecessary Conflicts due to Relative Sizing: The understanding of like or similar tasks may vary for each team member. This leads to conflicts in terms of effort identification. Also, the complexity may increase due to different subjective understandings.
- Dependency on Skilled Team: The scale for Relative Sizing differs from project to project. Due to this, Relative Sizing is not very relevant if the team is not skilled enough. The unskilled team members face difficulty in accurate planning which causes the project estimate to become inaccurate.
- Less Precise for Smaller Projects: It is easy to compare the ongoing tasks with the projects on a large scale. However, if the project has small tasks, the relative sizing becomes inaccurate even if they are well-defined. This makes Estimation by relative sizing less precise for the smaller project.
Estimation by Analogy and Relative Sizing
Project Managers put a lot of time and effort to successfully deliver the project. What they need is a robust technique to estimate their project. In Project Management, Analogous and Relative-Size Estimation are popular techniques that allow us to predict the efforts required for the project tasks. Also, we can compare the efforts for new tasks with those of completed ones so that we can analyze our workflow efficiency and resource availability.
