thereafter serves as the basis for further development,and that can be changed only through formal change control procedures.na baseline is a milestone in the development of software that is marked by the delivery of one or more software configuration items and the approval of these SCIs that is obtained through a formal technical review6These slides are designed to accompany Software Engineering:A
