Yes—basic Scrum is primarily a team-level framework.
Scrum
Scrum explains how one cross-functional team manages work through:
- Product Backlog
- Sprint Planning
- Sprints
- Daily Scrum
- Sprint Review
- Retrospective
- Product Owner, Scrum Master, and Developers
Scrum itself gives only limited detail about coordinating many teams.
Multiple Scrum teams can work on the same product, but they normally need additional coordination arrangements, such as:
- a shared Product Goal and Product Backlog;
- common integration standards;
- cross-team dependency management;
- synchronized Sprints;
- Scrum of Scrums;
- or a scaling framework such as SAFe, Nexus, LeSS, or Scrum@Scale.
Kanban
Kanban can be used at several levels:
- one individual;
- one Agile team;
- multiple teams;
- a department;
- a program or value stream;
- a portfolio.
For example, a multi-team Kanban board might show:
Requested → Analysis → Team Development → Integration → Validation → Released
Different teams may be responsible for different parts of that flow.
However:
A Kanban board alone does not automatically coordinate multiple teams.
The organization still needs:
- shared workflow policies;
- dependency visibility;
- WIP limits;
- clear ownership;
- integration agreements;
- escalation mechanisms;
- regular coordination meetings.
Scrum versus Kanban at scale
| Question | Scrum | Kanban |
|---|---|---|
| Primary focus | Team delivery within Sprints | Flow of work through a system |
| Usually starts at | Team level | Team or workflow level |
| Can involve multiple teams? | Yes, with additional coordination | Yes, through a shared end-to-end workflow |
| Main control mechanism | Sprint timebox and Sprint Goal | Pull system and WIP limits |
| Common metrics | Velocity, Sprint burndown | Lead time, cycle time, throughput, WIP |
| Does it fully solve enterprise coordination? | No | No |
In SAFe
SAFe provides the layer for coordinating multiple teams.
Each team may use:
- SAFe Scrum, or
- SAFe Team Kanban.
Then the Agile Release Train coordinates them through:
- PI Planning;
- PI Objectives;
- Program Board;
- cross-team dependencies;
- ART Sync;
- System Demo;
- shared cadence;
- RTE facilitation;
- program-level risk management.
GlobalZipCart example
Each GlobalZipCart feature group can operate as a Scrum team:
- Team 1: User Accounts
- Team 2: Catalog and Search
- Team 3: Cart and Checkout
- Team 4: Payments and Fraud
- Team 5: Orders and Fulfilment
- Team 6: Reviews and Recommendations
Their individual Sprint Planning is Scrum.
When all six teams coordinate their four-sprint plans, dependencies, risks, and PI Objectives, that is the SAFe multi-team layer.
Teaching line
Scrum mainly manages one team. Kanban manages flow and can span one or many teams. SAFe provides structured coordination across multiple Scrum or Kanban teams.
