Software configuration management

• SCM manages the analysis phase of a software project

• Promotion is a new version internally available for developers

• Configuration items are identified during requirement elicitation

Change management

• A version is changed by implementing new bug fixes

• Change policy lists criteria a promotion or release have to conform to

• Change management just handles the naming and creation of new version

Version control systems

• Distribute VCS does not enable developers to work offline

• VCS allows multiple developers to view the same file sequentially through a lock token

• A merge conflict occurs if multiple developers modify the same part of the same file

Branch management

• The development branch gets used to develop new code to solve a certain issue

• A review tries to make sure that no faulty code gets promoted

• To prevent merge conflicts one should push regularly to the development branch

Continuous integration

• A disadvantage is having too many executable versions of the system

• In regression testing executing large tests suits after each change is quickly done and finds many errors immediately

• Build Agents are used to run build processes in parallel

Release management

• A release manager plays the role of a liaison between different business units to achieve on timely delivery of software products

• The software project should only be delivered after the implementation of everything was completely done

• Release management slows down publishing the software product to the market, because it goes through many cycles first before release
