In testing phase, the effort distribution is upto
Correct Answer: D
Question 112 Explanation:
● Effort estimation is the process of predicting the most realistic amount of effort (expressed in terms of person-hours or money) required to develop or maintain software based on incomplete, uncertain and noisy input.
● Effort estimates may be used as input to project plans, iteration plans, budgets, investment analyses, pricing processes and bidding rounds.
● The strong overconfidence in the accuracy of the effort estimates is illustrated by the finding that, on average, if a software professional is 90% confident or “almost sure” to
include the actual effort in a minimum-maximum interval, the observed frequency of including the actual effort is only 60-70%.
● Currently the term “effort estimate” is used to denote as different concepts such as most likely use of effort (modal value), the effort that corresponds to a probability of 50% of not
exceeding (median), the planned effort, the budgeted effort or the effort used to propose a bid or price to the client
