摘要

Webster defines the act of estimating as "1. A rough or preliminary calculation, as of work to be done. 2. An opinion: judgment." While this is all that is defined in theory, in practice, 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).rnThis paper will explore the collaborative process as it unfolded for two Regence analysts tasked with building a model that estimates the completion date for the software testing cycle. 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 many problems encountered and limitations to implementing ideal solutions are chronicled along with the authors' experience-based recommendations for readers facing similar challenges in their own profession.rnMuch has been written on the subject of software development and testing by noteworthy authors. As such, it is not the authors' intent to expound or refute the validity of their work. Rather, the intent is to inform the reader of the understated complexity involved in building software testing models, to share some of the limitations we discovered are inherent in all models, and to encourage a collaborative approach among the in-house talent of their organization to produce a useful estimating model.
