In what units was task evaluation measured — in hours? Were there large tasks lasting several days or more than a week?

Task estimation is usually measured in hours, which allows for more precise planning and tracking of execution time. Depending on the project and methodology, tasks can vary in size:

• Short tasks: from a few minutes to several hours.
• Medium tasks: from several hours to one or two days.
• Large tasks: can take several days or even more than a week.

For large tasks, it is common to break them down into subtasks to simplify estimation and management. For example, implementing new functionality can be divided into design, layout, integration, and testing, each estimated separately.

Thus, yes, hour-based estimation is standard, and large tasks spanning several days or more than a week do occur, but they are usually divided into smaller parts for convenience.
