What is “codeBeamer”?
• … an Application Lifecycle Management platform, supporting
development teams to manage their processes from requirements
to release.
• … increases productivity, provides full traceability, improves and
reduces costs by centralized management of processes, users and
projects.
• … offers collaboration and supports users to achieve an increase in
efficiency of up to 50%.
• … in practical use: a great collaboration solution!

© 2010 Intland Software 14
Scrum V-Model
Advantages
• Light weighted process/ project management
• Short iteration cycles, Sprints
• Easy to learn
Advantages
• Clear definition of project phases
• Complete overview of the whole process
• Industries proven
Disadvantages
• No overview of the whole process
• High communication effort (daily Scrum)
• Less architectural overview
Disadvantages
• Less flexibility• No clear resource disposition
• Long iteration cycles

Combination of Scrum and V-Model in codeBeamer
• In codeBeamer, the artecfacts of both methods are combined - in
one project allowing to use the roles for Scrum and the defined
roles in V-Model.
