Systems and methods for facilitating a common platform for multiple users working parallelly in an enterprise environment are described. When a request is received along with requirements for adding a new feature in an existing application, the system fetches contract information associated with the existing application. The system further provides the contract information to a first user and a second user. Post receiving the contract information and requirements, the first user creates one or more test cases and the second user develops a source code for the feature to be added into the existing application. The system executes the one or more test cases for testing the validity of the source code and further integrates the source code into the existing application.
