The document discusses software estimation and defines key terms. It defines an estimate as a tentative evaluation or rough calculation. An estimate is a preliminary calculation of a project's cost or a judgment based on impressions. A target is a statement of a desirable business objective with a defined deadline, while a commitment is a promise to deliver specific functionality by a certain date. The document advises treating estimation as an unbiased process while planning should seek to achieve goals.
