It will increase end users’ productivity and reduce the burden on development teams.” Gartner, 2023 https://www.gartner.com/en/articles/what-is-platform- engineering © 2024 Thoughtworks

13. Pay attention to people and organisations throughout the lifecycle Create the right foundations ● Understand the user ● Clarify value © 2023 2024 Thoughtworks Engage and enlist ● Build trust ● Measure progress Operate and evolve ● Funding models ● Prioritisation

17. Developer surveys are quick and easy Validating and quantifying lessons from qualitative interviews DORA metrics to measure effects on operational performance Measuring team maturity in typical problem areas © 2024 Thoughtworks 17

21. Value Challenge with internal developer platforms Indirect Impact to Business Outcomes → 2nd class status Value is not Static → Unclear on investment needed and the urgency Challenge Hard to Quantify and Articulate → Enabler Platforms © 2024 Thoughtworks Need upfront investment → Concerns with upfront investment

22. Platform Value Cycle Measure Value Platform Value Metrics Build the right thing Assess how well the platform is delivering on its objectives Define Value Platform Value Model Model cost, value over a timeline for decision making © 2024 Thoughtworks Build the thing right

23. Platform Value Model Model that supports various cost factors and scenarios, extensible depending on specific needs of a given technical platform product investment. Models costs and value over a timeline Assesses optimistic and pessimistic scenarios Accommodates change during execution Ability to model Realized vs. Projected value Accommodates varying success metrics © 2024 Thoughtworks Structure that can be extended for any other technology investments

25. Build trust through early developer engagement These should become less time consuming and frequent as the platform matures Effort Coding Consulting Consulting Time Continuously Pivoting X-as-a-Service © 2024 Thoughtworks Collaboration

27. Measure your success transparently Platform success metrics to consider Lagging Number of security incidents Leading Number of support tickets Build, test, deploy time Onboarding rates Reuse Number of workloads deployed DORA metrics Availability © 2024 Thoughtworks CSat, NPS

29. If you’re going to measure engineering performance… • Have you baselined your metrics? • Do you understand the natural variation in those metrics? • Are you relying on a single metric or a composite? • Do you know what failure thresholds are? Success? • What actions will you take if your metric isn’t on target? © 2024 Thoughtworks
