Effective Test Strategy model for ensuring FTR of hot-fix

The purpose of this paper is to present best practices like; early deployment of testers, recording details to analyze the defect injection reason, increasing effectiveness of the unit testing by the developers, continuous upgrade of knowledge base, publishing of resolution notes (which highlights the problem, corrective / preventive actions and the affected modules), staging of production environment to validate the fix before shipping and increasing test automation to eliminate the regression defects. This paper elaborates developing a Test Strategy model which helps in ensuring First Time Right (FTR) delivery of Hot-Fix and hence improving customer satisfaction.
