How do you assess the duration of task completion in your current role?

The estimation of task duration is usually based on breaking down the task into smaller subtasks and analyzing experience with similar tasks. The expert judgment method is often used, considering complexity, workload, and potential risks. To improve accuracy, techniques such as:

• Estimation in hours or story points (if Agile is used)
• Analysis of past tasks with similar requirements
• Adding a time buffer for unforeseen difficulties

For example, if the task is to implement a new API, I break it down into design, coding, testing, and integration, estimate each part, and sum the estimates.
