Allette Systems, Australia

Abstract

This chapter summarizes the CoBRA application in the context of Allette Systems Pty. Ltd., Australia (Allette). In the context of Allette, we developed a very simple effort model. Based on the experiences from the previous applications and the small size of the Allette company, we aimed at building a simple effort model. In particular, we avoided modeling indirect influences on effort.

  This conference paper provides a brief overview of the CoBRA application at Allette Systems. In addition to what we presented in this book, the paper presents the results of the multiplier analysis (Step 8). Moreover, the authors compare the predictive power of the CoBRA method to two alternative approaches: expert judgment and simple statistical regression.

  This conference paper investigates the use of alternative software sizing methods for the purpose of project effort estimation in the context of Allette Systems. The authors compare the predictive performance of ordinary least squares regression when applied with two alternative software sizing methods, Web Objects and Function Points, to estimation based on expert judgment.

  This master thesis documents the detailed process of the application of CoBRA at Allette Systems. For each model development step, the author provides an in-depth insight into the analyses she performed and the results she obtained. Moreover, the appendices list the tools used for developing the CoBRA model and the outcomes of the individual modeling steps.
