Here is the short description of our sprint that we used in our previous project. Each "Release/Version" is a  sprint  in our project. Each sprint takes  2 weeks  (including weekends-14 days). Each day everyone in the team will add his/her own  stand-up note .(what she has done  yesterday , what she is going to do  today , and most importantly is there anything which causes  problems  and does not let him/her go forward.) Last 2 days of each sprint are to complete  unit tests, fix bugs and stabilize the release . During last 2 days of sprints no new functionality is added to the system. If a ticket is not completed with unit tests or is not reliable yet, it is  moved to the next release  but it is not included in the current release. We only work to  stabilize  the current release for these 2 days. Happy coding...
