This blog page is dedicated to the resources used to estimate software-intensive systems using traditional and agile development methods. The reason for this resource page is the lack of understanding of how to estimate, the urban myths about software estimating, and the fallacies that estimating is not needed, when developing software, in the presence of uncertainty, when spending other peoples money. Estimating Probable System Cost,” Stephen A.

Their music is the soundtrack of an era and continues to influence musicians to this day. According to NASA, there were an estimated 400,000 people involved in making the moon landing possible. This included teams of scientists, engineers and technicians, many who had not worked in aerospace before. There was no central government and the risk of the new nation falling apart was even more of a concern than it is today!
