This page simplifies the differences between Scrum and SAFe

The short version

ScrumSAFe
One Team working on small updatesSeveral Teams working on cross functional deliveries
Self organised teams managed by the scrum masterStructured governance with Lean leadership
Deliver Products in IncrementsDeliver cross team solutions
Deliver in Sprints 2-3 weeksDelivery in program increments (8 to 12 weeks)
Sprint Planning at the product/team levelPlanning of P1s across functions
Product Backlog for the teamTeam, Program & portfolio backlog
Best for single product deliveryBest at enterprise delivery level
Basic tools like JiraNeeds scaled tools (Jira Align)

The Long Version

Feature/AspectScrumSAFe (Scaled Agile Framework)
Primary ScopeDesigned for small, organising teams (typically 3-9 members).Designed for large enterprises to scale Agile practices across multiple teams, programs, and portfolios (can involve hundreds or thousands of people).
FocusDelivering high-quality software/products iteratively and incrementally within a single team.Aligning large numbers of Agile teams around shared business goals, coordinating work across dependencies, and delivering value at an enterprise level.
Framework TypeA lightweight, empirical process framework.A comprehensive knowledge base of organizational and workflow patterns, integrating Agile, Lean, and Systems Thinking principles.
PrescriptivenessLess prescriptive, providing a flexible set of rules, roles, and events. Teams have more autonomy to adapt.More prescriptive, offering detailed guidance on roles, events, and artifacts across multiple levels (Team, Program, Large Solution, Portfolio). This provides structure and consistency at scale.
Team StructureThree core roles: Product Owner, Scrum Master, Development Team.Builds upon Scrum teams but introduces additional roles at higher levels, such as Release Train Engineer (RTE), Product Management, System Architect, Epic Owner, and Lean Portfolio Management.
Planning CadenceSprint Planning: Typically 1-4 weeks (common is 2 weeks).Program Increment (PI) Planning: A large-room event every 8-12 weeks where multiple teams on an Agile Release Train (ART) align on shared objectives, dependencies, and deliverables for the upcoming PI. Teams also conduct shorter iteration (Sprint) planning within each PI.
Timeboxes/IterationsSprints: Fixed-length iterations, usually 1-4 weeks.Iterations: Typically 2 weeks within a PI. SAFe also uses PIs (Program Increments) as larger timeboxes for planning and delivery across multiple teams.
BacklogsProduct Backlog: Managed by the Product Owner. Sprint Backlog: Managed by the Development Team for a single Sprint.Team Backlog: For individual teams. Program Backlog: Managed by Product Management for an ART. Solution Backlog: For Large Solutions. Portfolio Backlog: For strategic initiatives managed at the portfolio level.
Dependency ManagementTeams largely self-organise and manage dependencies within their small scope. May struggle with complex inter-team dependencies.Provides explicit mechanisms and roles (e.g., Release Train Engineer, PI Planning) to identify, visualize, and manage dependencies across multiple teams and Agile Release Trains.
Continuous ImprovementSprint Retrospective: At the end of each Sprint, the team inspects its process and adapts.Inspect & Adapt (I&A) Workshop: A structured event at the end of each PI to reflect on the program’s performance and identify improvements. Individual teams still conduct Sprint Retrospectives.
AlignmentPrimarily driven by the Product Owner’s vision and direct team collaboration.Emphasizes strong alignment across all levels of the organization through shared vision, strategy, and coordinated planning events like PI Planning. Information flows both top-down and bottom-up.
Customer FocusDelivers increments frequently to gather rapid customer feedback.Aims to deliver value to customers at scale by aligning all teams and programs with strategic objectives and customer needs.
Cost & OverheadRelatively low overhead, suitable for startups and smaller projects.Requires more investment in training, roles, and coordination, suitable for large enterprises with the resources to implement it.
FlexibilityHigh flexibility, teams can tailor practices to their specific needs.Less flexible due to its prescriptive nature, which provides standardization but may limit individual team autonomy compared to pure Scrum.
