Lead a team of four C#/.NET, Java, and PHP developers. Introduced, evangelized, and lead the use of Fagan’s Software Inspection methodology, a process that dramatically reduces development time and costs and improves the quality of the software and the predictability of the development process. Despite initial skepticism (code reviews had been used several times in the past), the developers became the strongest proponents (and greatest beneficiaries) of the Inspection process. Within several months, management required Inspections on all code, prompted by the significantly reduced development costs and dramatically decreased defects that had been achieved.
