The main difference between Scrum and Scrumban is that the former is more structured, while the latter focuses on optimizing workflow and team collaboration. This has some important knock-on effects that you should be aware of.
As a more restricted process, Scrum applies firmer rules and defined roles (such as “product owner” and “scrum master”). It also relies heavily on deadlines and time estimates for managing workloads. In addition, its use of sprints and regular meetings means team members’ performance is constantly tracked.
All this structure is helpful since Scrum is often used on large projects. However, this rigidity also means it is more prone to issues, such as sudden changes in a project’s scope.
Scrumban, meanwhile, is much more flexible than Scrum. With fewer rules to follow, product managers can select which aspects of Scrum to include in the framework. This means it doesn’t suffer from overly prescriptive processes, deadlines, or unnecessary meetings. Ultimately, this means Scrumban is far better equipped than Scrum to respond to sudden changes in project scope or to meet shorter release schedules.
