SDLC (Software Development Life Cycle) and Scrum are two different approaches to software development. The primary differences between SDLC and Scrum are:
Methodology: SDLC is a linear, step-by-step approach to software development that includes a set of phases that must be completed in sequence, whereas Scrum is an iterative and incremental approach that breaks the development process into small, iterative cycles.
Requirements: In SDLC, requirements are defined at the beginning of the project and remain relatively fixed throughout the development process. In Scrum, requirements are continually refined and prioritized through the product backlog and are subject to change at any time.
Roles: In SDLC, the roles of the development team are more fixed and defined, with clear lines of responsibility and accountability. In Scrum, team members work more collaboratively and interchangeably, with shared responsibility for the success of the project.
Planning: In SDLC, planning is done at the beginning of the project and is more comprehensive, while in Scrum, planning is done at the beginning of each sprint and is more flexible and adaptable.
Delivery: SDLC is designed for delivering the final product after all the phases are completed, whereas Scrum provides for delivering a potentially releasable increment of the product at the end of each sprint.
