Advantages of Relative-size Estimation
- Easy Adaptability: The historical data is not always available or accessible. But the comparison of tasks with similar activities is easy. We do not need to recalibrate the estimation metrics to adapt to the requirements. Thus, the Estimation by Relative Sizing is easy to use.
- Enhanced Customer Satisfaction: The stakeholders or customers become more satisfied by getting comparisons between similar tasks to estimate the project resources. Thus, it is easy to convince them of parameters such as project deadlines or delivery.
- IT Reduces Bias: The project experts do not need to rely only on the first piece of information to make a decision. Also, absolute values do not influence the teams easily. This reduces the bias in the project estimation and increases the accuracy.
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.
