1) Critically evaluate any two software configuration management activities used for controlling and tracking the changes during the software development cycle for the scenario selected in assignment 1. Support your discussion with appropriate literature. (20 marks) 2) Version Control System makes the development process easier and faster and allows tracking and controlling modifications to data over time. With the help of a suitable tool, demonstrate the key features available to track and manage changes ( masterl file and branch file creation,log history, issue tracking, create collaborative work environment) related to software configuration management processes. Attach the screenshots as evidence. Provide a critical reflection of the effectiveness of the tool in performing the change control activities.
