6. Scaling that works So what s scaling?
8. If you can only scale-up or scale out, You are not scaling. You are bloating.

13. Before scaling… ✤ Have at least two great scrum teams in your organization ✤ Teams that know how to improve products, process, and teams.

15. Scrum@Scale: Definition • Scrum (n): A framework within which people can address complex adaptive problems, while productively and creatively delivering products of the highest possible value. • Scrum@Scale (n): A framework within which networks of Scrum teams operating consistently with the Scrum Guide can address complex adaptive problems, while creatively delivering products of the highest possible value. • NOTE: These “products” may be hardware, software, complex integrated systems, processes, services, etc., depending upon the domain of the Scrum teams. © 1983-2018 Jeff Sutherland & Scrum Inc. 15
16. Scale-Free Architecture • If you want to scale exponentially you need a “scale-free” architecture • Otherwise you risk introducing waste into the system and slowing the whole organization down • You will not achieve linear scalability • Scale-free architectures are pervasive in biology (ex. neural networks) • They are able to evolve to perform new functions more rapidly than an alternative network design Digital Darwinian world reveals architecture of evolution Source: http://chronicle.uchicago.edu/061207/darwin.shtml © 1983-2018 Jeff Sutherland & Scrum Inc. 16 Diagram of a scale-free network that contains components with a highly diverse level of connectivity. Some components form highly interconnected hubs, while other components have few connections, and there are many levels of interconnectivity in between. Scale-free networks are pervasive in biology. Computer simulations at the University of Chicago show that scale-free networks are able to evolve to perform new functions more rapidly than an alternative network design.
17. Scaling Challenge: Bureaucracy & Hierarchy • A bureaucratic processes creates poor decision latency. • Everything we do requires so many sign-offs that nothing gets done. • We have layers upon layers of managers. • Therefore, we need a Minimum Viable Bureaucracy. © 1983-2018 Jeff Sutherland & Scrum Inc. 17
18. The Scaled Daily Scrum: The SM Role Scaled NEW ROLE • In order for the SoS to be most effective, we need a Scrum of Scrums Master (SoSM) to ensure that: • Impediments are shared and removed • Knowledge is spread and standardized • Dependencies are discussed and resolved • The SoS functions as a Release Team •Scrum must scale in an organic way consistent with the Scrum Guide or it will be slow •Using a Scrum of Scrums reduces communication paths but increases communication saturation © 1983-2018 Jeff Sutherland & Scrum Inc. 18
19. Scaled Daily Scrum (SDS) SoS • • Exists to coordinate the Scrum of Scrums and remove impediments to the delivery of value to customers The SDS event mirrors the Daily Scrum • An opportunity to re-plan in order to achieve the Sprint goal for the SoS • • Surfaces impediments Shares learnings for continuous improvement © 1983-2018 Jeff Sutherland & Scrum Inc. 19 SM SM SM SDS SM SM
20. The Executive Action Team • Accountable for the quality of Scrum in the organization • Owns the Organizational Transformation Strategy • Owns the Transformation Backlog and “eats impediments” that block it • Removes impediments not handled at the Team level due to scope, budget, or corporate political power • Executes the Transformation Strategy or delegates it to a center of expertise (often called the Agile Practice) • Measures and improves the quality of Scrum in the organization to build capability for business agility © 1983-2018 Jeff Sutherland & Scrum Inc. 20

23. Who should be on the EAT? ? • A leader who can change company policy without having to ask permission [ex. COO, CIO, CTO] • Someone who can write a check [ex. VP of Finance] • Someone who is a Scrum Star [aka. Agile Champion] • • Leaders who can motivate change • Someone from Legal/Compliance Someone from People Ops HR] © 1983-2018 Jeff Sutherland & Scrum Inc. [ex. 23

26. The MetaScrum Backlog Refinement • A MetaScrum Scaled Backlog Refinement Meeting is a gathering of Key Stakeholders, Leadership, Product Owners, and Team members. • Run by Chief Product Owner • Did anything change that would change the strategy or priorities? • Aligns enterprise around single backlog • The forum for stakeholders to express preferences, remove blocks and provide resources needed (they should not try to alter product vision between MetaScrums) • Decompose upcoming backlog © 1983-2018 Jeff Sutherland & Scrum Inc. 26
27. Scrum Master and Product Owner Functions Scale Coordination Differently Scrum Master Product Owner • Share best practices • Collectively solve problems & remove impediments • Maintain clear and consistent product vision • Optimize business value • Respond decisively to changing market Product PO team Scrum of Scrum of Scrums Component PO team Scrum of Scrums CPO Component PO team Team CPO PO T T T © 1983-2018 Jeff Sutherland & Scrum Inc. 27 T T T CPO PO PO T T T T T T PO T T T T T T
28. Why would we need an Agile Practice? • In a smaller company or implementation, the EAT can both develop the transformation and implement it • As a company grows or as the implementation gets larger, it is common that the executives who create the transformation strategy do not have the time to dedicate to implementing it • As such, they may delegate the implementation to another group, which is known as the Agile Practice © 1983-2018 Jeff Sutherland & Scrum Inc. 28
