Product Development Flow - how to scale beyond 20 developers - Johannes Mainusch & Aya El Settini & Wolf Siberski - NewStore

Product development is pretty much jammed up in most organisations beyond 20 and adding more developers or teams to the company often results in slow down and chaos. Like a car that chokes when hitting the accelerator. But there are rare examples, where teams collaborate and produce a regular and scalable output of new features. This can only be achieved by radically reorganising, ensuring management collaboration and distributing responsibilities to experts. And by forgetting most of the old and dysfunctional management paradigms.

4. 4 IN DEPENDENCE
5. 5 1. Load test revealed a problem 2. tpauling discovered a lock protecting a shared resource in our legacy go code. 3. This happened in a shared librar 1. running 1000 parallel routines went from 8,4 minutes to 14 seconds. 1. We fixed part of out 108 microservice structure just before black friday… 1. → our go code needs fixing 2. → this is a metaphor for independence of processing units... a lock in legacy
6. 6 if you want to utilize parallel processing units, independence is key. Amdahl’s law
7. 7 highly aligned and loosely coupled apply Amdahls law to an organisation ⇒ highly aligned + loosely coupled teams
11. 11 Ownership Team Culture Shared Success Ubiquitous Language Ingredients for Independent Teams
12. 12 OWNERSHIP
13. 13 You build it, you run it, you own it
14. 14 Home, Sweet Home
15. 15 Own Your Future • Vision • Customers • Success Criteria • What you DON’T do Team Purpose
16. 16 Assets and Liabilities Code API Backlog Process CI / CD Infrastructure
17. 17 Team Purpose and Business Vision Team Purpose Business Vision
19. 19 NERD- LOGICAL SAFETY

29. 29 SHARED SUCCESS
30. 30 Ensure future success & share it!
31. 31 highly aligned and loosely coupled
32. 32 Things we share at NewStore Shared Values Shared Objectives Quarterly Goals where the whole company is incentivized to support reaching them
33. 33 • Shared success → if we achieve our engineering goals, the whole company profits. ´ Q4 2019: 105% goal achievement
34. 34 shared success helps us in becoming highly aligned. ...but there are still a lot of misunderstandings. People use the same words but mean different things...
36. 36 UBIQUITOUS LANGUAGE
37. 37 A project faces serious problems when its language is fractured (Eric Evans)
38. 38 Language of the Organization • Use Ubiquitous Language (DDD) • Use business terms • Share across all departments • Use core terms in communication and code ORDER! ORDER! ORDER!
39. 39 Language of the Team • Extends the ubiquitous language • Business terms relevant for the team purpose • Use with neighbor teams and business stakeholders • Reflect team language in API API C A P T U R E AU T H O R I Z E R E F U N D R E V O K E S T A T U S
42. 42 Takeaways for the audience 1. Independence of teams → apply Amdahl’s law to the organisation 2. Ownership → let teams define their purpose within the organization 1. To enable teams to take risks and take responsibility for what the own → metaphor psychological safety 2. Shared success → if we achieve our engineering goals, the whole company profits. 3. Ubiquitous language → ensure alignment by speaking the same language
