AOEconf17: Agile scaling concepts
The document discusses agile scaling concepts presented by Christof Braun at AOEConf 2017, emphasizing that productivity declines with larger teams due to communication overhead and dependencies. It outlines the challenges of scaling agility and introduces various frameworks like SAFe, Large Scale Scrum, Nexus, and Scrum@Scale, each with different structures to address scaling needs. Additionally, it encourages a flexible approach to scaling by adapting methods to suit specific project requirements while adhering to agile principles.

- 2. TEAMS FIRST AOECONF 2017Agile Scaling Concepts Christof Braun – Manage Agile! Productivity (per person) goes up in a team Multiple perspectiv es Help each other Multiple specialti es Self organisat ion Adapt to changes Continuou s improvem ent Fast feedback
- 3. BIGGER PROJECTS NEEDMORE PEOPLE Very big projects will take too long with nine people. AOECONF 2017 Agile Scaling Concepts Christof Braun – Manage Agile! Communication overhead increases with each new person But productivity decreases: Ringelmann effect Dependencies across teams cause delays
- 4. THE FIRST RULEOF SCALING AGILITY 1.Do not scale agility AND THE SECOND RULE IS… 2.Do not scale agility AOECONF 2017 Agile Scaling Concepts Christof Braun – Manage Agile!
- 5. NON-SCALING OPTIONS Takelonger to deliver • It’s cheaper! • 9 people 12 months vs. 18 people 7-8 months • Create intermediate results to deliver usable versions – progress for customer Split product or solution into separate, independent entities with one team for each entity • Common look and feel through shared style guides and UI technologies • Avoid shared date • Do not try for synergies and shared code components • Minimal and stable shared interfaces • Common architectural guidelines but no common architecture AOECONF 2017 Agile Scaling Concepts Christof Braun – Manage Agile!
- 6. BUT… Sometimes itjust doesn’t work (or so it seems)… • Coordinated deliveries • Unavoidable dependencies With increasing popularity of agile methods, scaling needs occur more and more Do-it-yourself scaling does not suffice anymore Pundits started to offer solutions with the claim to general applicability And so the agile scaling wars began… AOECONF 2017 Agile Scaling Concepts Christof Braun – Manage Agile!
- 7. CURRENTLY IN THELEAD: AOECONF 2017 Agile Scaling Concepts Christof Braun – Manage Agile!
- 8. AOECONF 2017 AgileScaling Concepts Christof Braun – Manage Agile! Scales to arbitrary size Covers all (most) of an organization Scrum and Kanban New roles, artefacts and meetings Value streams are developed in Release trains Program increment (PI) covers 4-6 sprints PI planning Innovation & planning sprint
- 9. SAFe CHARACTERISTICS Author:Dean Leffingwell (Method Guru, long tenure at Rational) Prescriptive Hierarchical Upper levels with impact on large part of organisation “Everything in it” framework Best suited for very large enterprises AOECONF 2017 Agile Scaling Concepts Christof Braun – Manage Agile!
- 10. LARGE SCALE SCRUM(LeSS) AOECONF 2017 Agile Scaling Concepts Christof Braun – Manage Agile! One PO, one backlog Only Scrum Sprint Planning 1 together Team retros and overall retro (with team rep only)
- 11. LeSS CHARACTERISTICS Authors:Craig Larman, Bas Vodde (Lean software development) Up to eight teams • LeSS Huge allows to scale beyond that More responsibility for teams – e.g. write user stories, customer/user contact, coordinate as teams see fit Minimalist (lean…) AOECONF 2017 Agile Scaling Concepts Christof Braun – Manage Agile!
- 12. NEXUS (KEN SCHWABER) AOECONF2017 Agile Scaling Concepts Christof Braun – Manage Agile! “Exoskeleton for scaled scrum” Scrum only Up to 9 teams New role: Nexus integration team The one PO A scrum master Team members Teams send representatives to overall planning and retro
- 13. SCRUM @ SCALE(JEFF SUTHERLAND) AOECONF 2017 Agile Scaling Concepts Christof Braun – Manage Agile! Meta framework A basis for discussion Which issues need to be addressed? Which roles and which organizational level is involved Scrum only PO cycle Strategy Requirements Release planning Scrum master cycle Coordination Continuous improvement
- 14. ROLL YOUR OWN AOECONF2017 Agile Scaling Concepts Christof Braun – Manage Agile! Large agile projects are all different. One solution will not fit all needs. Pick and chose the parts that fit YOUR project. Add your own ideas. Create a collection of scaling patterns and combine as required. Mind the agile principles.
