Evaporate the Gates: VSM Workshop

When you are lost, how do you find your way? This session explores the basic elements of uncovering who your customer really is, what is value and how it flows end-to-end. The objective of this session is to lay the foundations for creative and collaborative visualisation combined with data-driven insights to pave the way for faster feedback loops, accelerate learning, and the benefits of adopting continuous delivery capabilities.

What will I take away from the session? You will have the hands-on ability to start your journey towards creating a metric-driven organisation, by creating a Value Stream Map for your product.

1. Evaporate the Gates Value Stream Mapping for Continuous Delivery 80 mins Ben Dodd @bendodd Kevin Austin @kev_austin Workshop from @AgileLeanIre #ALI2019
2. Ben Dodd @bendodd | Kevin Austin @kev_austin | #ALI2019 What we will explore together today
3. Ben Dodd @bendodd | Kevin Austin @kev_austin | #ALI2019 Goals for our time today 1. This could be awesome, let’s do it! 2. This seems simple to start, let’s start! 3. I have a connected community of #ALI2019 folks I can collaborate with
4. Ben Dodd @bendodd | Kevin Austin @kev_austin | #ALI2019 Constraints, Blockers, Gates Why do they persist? How do you know where to improve? Exercise
5. Ben Dodd @bendodd | Kevin Austin @kev_austin | #ALI2019
6. Ben Dodd @bendodd | Kevin Austin @kev_austin | #ALI2019 6 HELP! • One night, once a year • 90% of revenue • 9 month manual deployment
7. Ben Dodd @bendodd | Kevin Austin @kev_austin | #ALI2019 What we are going to map Apply to our context Software delivery
8. Ben Dodd @bendodd | Kevin Austin @kev_austin | #ALI2019 Exercise 1. Get into groups of 3 2. Pick a value stream 3. Sketch it out 4. Starts & ends with the customer
9. Ben Dodd @bendodd | Kevin Austin @kev_austin | #ALI2019 Hint: it might look something (maybe) like this… Who is the customer? The VSM starts with the customer… …and ends with the customer Customer
10. Ben Dodd @bendodd | Kevin Austin @kev_austin | #ALI2019 A Value Stream Map A process map Visual focus point Data about the flow of work What are the key outputs?
11. Ben Dodd @bendodd | Kevin Austin @kev_austin | #ALI2019 Collaborative empirical clarity Team environment awareness Improvement opportunities What are the key outcomes? Continuous reflection Story telling over time Supports investment decisions
12. Ben Dodd @bendodd | Kevin Austin @kev_austin | #ALI2019 How can we create a VSM?
13. Ben Dodd @bendodd | Kevin Austin @kev_austin | #ALI2019 Walk 1: Process Map & People Walk 2: Anecdotal Metrics & Measures Walk 3: Measured Metrics & Measures 3 Passes: Walking The Line
14. Ben Dodd @bendodd | Kevin Austin @kev_austin | #ALI2019 Developer Tester Scrum Master Analyst Delivery Manager DBA Product Owner Security Monitoring Release Engineer UX Designer …who else? Collaborative Crowd-Sourcing
15. Ben Dodd @bendodd | Kevin Austin @kev_austin | #ALI2019 1. Everyone note down all of the processes involved, 1 per post-it note 2. Stick them on the wall or whiteboard in the order that they occur (discard duplicates) 3. Group them up until you have between 5 and 15 processes

20. Ben Dodd @bendodd | Kevin Austin @kev_austin | #ALI2019 LT: 1D PT: 3.5H C&A: 50% AR: 50% 1.What is the lead time? The lead time (LT) is the total amount of time from asking for, to delivery that a process takes, so including any time waiting in the queue 2.What is the process time? The process time (PT) is the amount of time it actually takes to complete the process. This must be equal to or less than the lead time. 3.What is the percent complete and accurate (C&A)? This is the percentage of time that a process has been completed without problems. 4. Based on lead-time and process time, we can now the activity ratio (AR) Step 4 Walk 2 Empirical Data

25. Ben Dodd @bendodd | Kevin Austin @kev_austin | #ALI2019 Exercise • Add data – rough guesses are good!

27. Ben Dodd @bendodd | Kevin Austin @kev_austin | #ALI2019 How can we improve using a VSM?
28. Ben Dodd @bendodd | Kevin Austin @kev_austin | #ALI2019 LT: 1D PT: 1H C&A: 50% AR: 14% 1. Evaluate the whole process Before we evaluate individual processes, should the end-to-end process be removed? Are processes upstream affecting a process? 2. Optimise for high %C&A Investigate why the quality of a process is low 3. Optimise for high Activity Ratio % Investigate why there is a difference between Lead Time and Process Time – can you reduce the queues? 4. Remove processes Before we look to optimise a process, can it be removed completely? 5. Automate or optimise a processes Finally, can we optimise a process to increase C&A or AR or reduce Lead Time

30. Ben Dodd @bendodd | Kevin Austin @kev_austin | #ALI2019 Exercise • Discuss and highlight areas to improve
31. Ben Dodd @bendodd | Kevin Austin @kev_austin | #ALI2019 Why do we VSM?
32. Ben Dodd @bendodd | Kevin Austin @kev_austin | #ALI2019 Fact-based & Non-political Visualise workflow Interaction awareness Understand our processes Empirical workflow measurement Why do we VSM? Empathy
33. Ben Dodd @bendodd | Kevin Austin @kev_austin | #ALI2019 Continuous improvement, not big bang We always want to improve :) Why Now? Credible co-created story telling, over time
34. Ben Dodd @bendodd | Kevin Austin @kev_austin | #ALI2019 Why Now? DevOps Research and Assessment (DORA) benchmarks Elite Low Performing Deployment Frequency For the primary application or service you work on, how often does your organisation deploy code? On-demand (multiple deploys per day) Between once per week and once per month Lead time for changes For the primary application or service you work, what is your lead time for changes (i.e., how long does it take to go from code commit to code successfully running in production)? Less than an hour Between one month and six months Mean time to recover (MTTR) For the primary application or service you work on, how long does it generally take to restore service when a service incident occurs (e.g., unplanned outage, service impairment)? Less than an hour Between one week and one month Change failure rate For the primary application or service you work on, what percentage of changes results either in degraded service or subsequently requires remediation (e.g., leads to service impairment, service outage, requires a hotfix, rollback, fix forward, patch)? 0-15% 46-60% “We’ve been doing agile, but.. ..we’re still in the red”
