Stop rolling the dice: an approach to effort estimation in software development by Luca Camerini
Estimate effort, not time, with a data-driven approach to software development estimation, considering parallelization, resource allocation, and uncontrollable factors, and leveraging tools and methods to support human judgment.
- Estimate effort, not time
- Individual mandates for activities, not linear approach
- Consider parallelization and resource allocation
- Decision-making process for estimation, not just guessing
- Pay attention to associated costs
- Understand that estimation is complex due to interactions and uncontrollable factors
- Mapping skills and efforts is crucial
- Consider non-linear correlation between resource numerosity and velocity
- Tool helps run estimation, provides guidelines and reminders
- Don’t underestimate the importance of estimation being a decision-making process
- Be aware of common mistakes and limitations
- Communication and sharing are key to successful estimation
- Tools and methods can help, but not replace human judgment
- Reflect on own experiences and adjust estimation accordingly
