Untangling software delivery with Team Topologi...

Untangling software delivery with Team Topologies, flow metrics, careful decoupling, and Adapt Together™️

The key predictive IT delivery metrics uncovered by the book Accelerate and the State of DevOps Reports - aka “DORA metrics” - point the way towards flow-centric operating models for every modern enterprise building and running software-enriched services. However, improving flow of value within an organization is often difficult due to cross-team dependencies and coupling: everything is tangled. In an organization with 700 software engineers, if 60% of the time is spent waiting on other teams - a typical industry flow efficiency - the financial penalty of dependencies and coupling is high. It is vital, therefore, to invest in decoupling and removing team dependencies - untangling - to enable value to flow better and more efficiently.

In this talk, Matthew Skelton - founder at Conflux and co-author of the book Team Topologies - explores techniques and metrics to help you untangle your software delivery, together with real-world examples of organizations successfully applying Team Topologies and related approaches to decouple teams and improve flow:

- Independent Service Heuristics (ISH)
- User Needs Mapping (UNM)
- The 4 key metrics (Accelerate/DORA)
- Flow efficiency and proxy measures

Increasingly, the ideas and patterns in Team Topologies (TT) are being applied worldwide not just in software/IT but increasingly in non-IT contexts like legal services, healthcare, education, and HR, resulting in quicker time-to-market and better ROI. These applications of TT point the way to an operating model for fast flow organizations.

Decoupling for flow is complimented by diffusion of knowledge for alignment and engagement using Adapt Together™️. Adapt Together™️ encourages and promotes flow-centric, humane, team-based ways of working that increase operational efficiency and staff engagement, leading to elevated customer and business outcomes.

Devised by the visionary leader in holistic innovation, Matthew Skelton - co-author of the award-winning book Team Topologies - together with insights and experience from colleagues and peers across multiple industries, Adapt Together™️ is an engaging, actionable way to produce lasting results in knowledge-work for bold, innovative organizations.

  1. Untangling software delivery with Team Topologies, flow metrics, careful decoupling,

    and Adapt Together™ Matthew Skelton, Conflux - co-author of Team Topologies Agile Yorkshire meetup | 04 September 2024 K28
  2. 3 Use balanced health metrics (DORA, flow, cost, blockers, etc.)

    + TT techniques (TIM, ISH, UNM) to help find good boundaries for fast flow by untangling (decoupling) separate services

  6. Team Topologies is the leading approach to organizing business and

    technology teams for fast flow, providing a practical, step-by‑step, adaptive model for organizational design and team interaction. 8
  7. 14 Team Topologies exposes any lack of clarity in purpose,

    conflict in priorities, or misalignment of incentives

  9. The cost of tangled software DORA metrics & TT to

    the rescue! Real examples of detangling How to detangle with metrics & TT 16
  10. 18 If each engineer in the organization is blocked for

    1 hour per working day, how much does this cost?
  11. 19 • Fully-loaded cost: €160k per year • 260 paid

    days per year • Total of 400 engineers
  12. 20 Engineer fully weighted cost per year Engineer cost per

    day Hours blocked per 8-hour day Days blocked per 260-day year Cost of blockers per engineer per year Number of engineers Total cost of blockers per year €160,000.00 €615.38 1 32.5 €20,000.00 400 €8,000,000.00 €8 million per year 💥

  16. 4 key metrics: ‘Accelerate’ lead time deployment frequency Mean Time

    To Restore change fail percentage Encourage fast flow
  17. 4 key metrics: ‘Accelerate’ lead time deployment frequency Mean Time

    To Restore change fail percentage Encourage operability
  18. What % of lead time is actual work? Example: 120

    hours / (120+630) x 100 = 16% Flow Efficiency 45
  19. 4 key metrics & ‘blocker count’ lead time deployment frequency

    Mean Time To Restore change fail percentage ‘blocker count’ as a proxy for flow efficiency 48
  20. Use 4 key metrics 📊 + “blocker count” to assess

    and find better service & team boundaries for flow 49
  21. “If we adjusted the service & team boundary here, would

    it improve the 4 key metrics?” 💓 50
  22. 54 “The Independent Service Heuristics (ISH) are rules-of-thumb (clues) for

    identifying candidate value streams and domain boundaries by seeing if they could be run as a separate SaaS/cloud product.” https://teamtopologies.com/ish
  23. 56 “User Needs Mapping attempts to capture the first 4

    steps of the Wardley Mapping process … for identifying potential team [and service] boundary” https://teamtopologies.com/unm
  24. 58 “[Team Interaction Modeling helps] to describe how to re-organize

    … teams and their interactions to achieve better flow and deliver value faster.” https://teamtopologies.com/tim

    Flow in a Market Leading Enterprise Platform” 61 https://www.youtube.com/ watch?v=y3OL7dv2l48 Fast Flow Conf 💖 https://www.fastflowconf.com/
  26. 64 Engineer fully weighted cost per year Engineer cost per

    day Hours blocked per 8-hour day Days blocked per 260-day year Cost of blockers per engineer per year Number of engineers Total cost of blockers per year €160,000.00 €615.38 1 32.5 €20,000.00 400 €8,000,000.00 €8 million per year 💥 Remember this? [Note: these are not figures from JP Morgan]
