When millions of project dollars are at stake, estimating requires the focused efforts of its end users (stakeholders) and a great many subject matter experts (SMEs).
This paper will explore the collaborative process as it unfolded for two Regence analysts who were tasked with building a model that estimates the date of completion for the testing cycle, which included improving the software to release quality. Neither analyst had a clear view of the path forward, but through collaboration began to define the problem, identify the limitations (of both the techniques employed and the data available), and to construct a defendable model that the senior leadership team could confidently present to its board of directors. The paper chronicles many of the problems encountered, and limitations of implementing ideal solutions along with the authors experienced-based recommendations for readers facing similar challenges in their own profession.
Much has been written on the subject of software development and testing by noteworthy authors; it is not the intent of this paperâ€™s authors to expound or refute the validity of their work. Rather, the intent is to enable the reader to identify the necessary stakeholders, explain the limitations inherent in all models and initiate a collaborative effort toward building an estimating model that works for their organization (within known constraints).
