5. Kanban Software Development Methodology

Just like Scrum, Kanban is one more agile framework that emphasizes the continuous enhancement of the software throughout the development process. 

Kanban does not contain any predefined roles and events. It can acceptable when you make changes. It depends on continuous delivery through time-boxed sprints. 

Kanban does not specify any team members or project management approaches. Preferably, the Kanban board is the most significant component. It helps list out future tasks while developing software. You can consider it a to-do list. It helps to categorize a team’s future activities or is in progress. 

Suitable to,

This methodology suits small teams and projects that need continuous modifications. A team of experts or a single person can work on various elements of the Kanban approach.
