Time estimation: It is the time (in hours) for each task/functional point. Effort Estimation: It is the total bandwidth each engineer has dedicated towards a project or task within the same project. Is the skill level play any role in differentiating between time and effort estimation? Replies: Posted By: Lipika Date Posted: 27Apr2007 at 3:54am Skill definitively play a role when defining the effort (man/days) needed. Be careful that the two components are not completely separated. If a development effort of 30 days is split between 3 developers, you could need to add additional coordination activities, thus increasing the initial effort.
