It has been observed by many researchers that software development projects are having various issues about cost, time, and quality. Many software development projects are exist which could not complete within their planned duration, within budgeted cost and as per expected quality. Various researchers have assessed various parameters on software development projects to examine the impact or relationship with other parameters. This research paper is intended to establish the relationship between software development projects Team Size with its Quality Variance. Implication of this paper shall be most useful to the software project managers to understand the impact of Team size on Quality Variance in the software development Projects. The result shows the there is a slightly positive correlation between the Quality Variance observed on the software project by software project authorities and Team Size of software development projects.
