Abstract
The required effort of a task can be estimated subjectively in interviews with experts in an organization in different ways. Interview techniques dealing with which type of questions to ask are evaluated and techniques for combining estimates from individuals into one estimate are compared in an experiment. The result shows that the interview technique is not as important as the combination technique. The estimate which is best with respect to mean value and standard deviation of the effort is based on an equal weighting of all individual estimates. The experiment is performed within the Personal Software Process (PSP).

Teams applying PBR are shown to achieve significantly better coverage of documents than teams that do not apply PBR, and the threats to validity are discussed so that external replications can benefit from the lessons learned and improve the experimental design.

The paper shows how to state a hypothesis and determine how much control is needed over the variables involved, and data analysis is shown to be a function both of the experimental design and the distribution of the data.
