Selecting the Right Estimation Technique

Choosing the appropriate estimation technique is crucial for accurate time estimation in software projects. In this article, we’ll explore different estimation techniques, including expert judgment, analogy-based estimation, and bottom-up estimation, and provide guidance on selecting the right technique for your project.

Expert Judgment

Expert judgment relies on the knowledge and experience of individuals or teams familiar with the project domain or technology. Experts use their expertise to provide estimates based on their judgment and past experiences. This technique is useful when historical data is limited or when dealing with complex projects where no standard estimation techniques apply.

Analogy-Based Estimation

Analogy-based estimation involves drawing parallels between the current project and similar past projects to derive estimates. By identifying similarities in project scope, complexity, and team composition, analysts can extrapolate estimates based on historical data. This technique is effective for projects with well-defined requirements and a sufficient repository of past project data.

Bottom-Up Estimation

Bottom-up estimation involves breaking down the project into smaller, more manageable tasks and estimating the time required for each task individually. These individual estimates are
