Pioneers of Parametrics: Origins and Evolution of Software Cost Estimation

Abstract

This article provides an historical account of the development of the field of software cost estimation, specifically the area of parametrics, through information obtained during interviews of 13 pioneers in the field. Cost model developers, users, and practitioners were interviewed with the intent to capture their views on the impact between cost estimation research and practice. Each perspective sheds light on the areas in which the field of parametrics has had an impact and which synergies have been influential in the development of the field. The implications of the findings are discussed in light of the future challenges for the field of parametrics.
