How do you assign defect to developers

Once we find a defect we will do retest again and we will intimate to my TL with defect sheet, He will send to Developers.If you r using Defect tracking tool,My TL will raise the defect in defect tracking tool,if you r putting more than 3 + Exp you can say I will log the defect in Defect tracking tool.If you r not using any tool for defect tracking then you can say that my TL will maintain all defects in one ExcelSheet after reporting to developers and he will track the defects .Once he receive the updates then he will intimate to tester(who tested that previously)then we will do retest that one.If it is a tool,once developer fix that defect they will update in tool,once they will update tool automatically generate an email and send to corresponding persons.
