Episode 149: Continuous Delivery with Dave Farley

Craig, Tony and honorary Revolutionist Pete Sellars are at YOW! Conference and sit down with Dave Farley, co-author of “Continuous Delivery” and they chat about the following

  • There are anti-patterns with doing XP at scale, continuous delivery was born from the learnings from that
  • Continuous delivery is just extending continuous integration to more of the software development practice (and continuous integration requires test driven development)
  • Continuous delivery works because it is the application of the scientific method to software development
  • If you work in an iterative, imperative, experimental way and you take continuous learning seriously and take cycle time as a serious measurement you will naturally drive out agile, lean, systems theory and DevOps
  • YOW! 2016 presentation “The Rationale for Continuous Delivery
  • Most common two ways to introduce continuous delivery to your organisation – need to get cover from senior management to make change or you do it secretly at the grass roots – the fast feedback cycle is important (build feedback in about 5 minutes and ready and deployable in about an hour)
  • DevOps is a terrible name – we are talking about collaborative cross functional teams and it is more than just developers and operations
  • Continuous delivery is focused on shortening the feedback cycle from having an idea to getting the idea into the hands of users and figuring out what our users make of the idea – that’s software development, to do whatever it takes
  • Continuous delivery is working in a way so that my software is always in a releasable state, continuous deployment is if all my automation says my software is in a working state I can just automatically push it to production
  • We have data to show that continuous delivery makes high quality software faster, creates more money for the organisations that use it, reduces defect rates significantly and makes people working in that environment happier
  • It changes the way you design, approach databases and the way you test
  • Scott Ambler’s “Refactoring Databases” book
  • Continuous Delivery tools still aren’t mature enough
  • The deployment pipeline is a seriously strategic resource because it is your only route to Production – need to be able to version and test it like any other Production code
  • It’s as much about the culture of the team than it is about the technology, it frees teams up to do experimentation

Episode 143: One Last Jam with The “Dude” David Hussman

The Agile community recently lost its friend and one of its most inspirational members in David Hussman. Craig and Tony were privileged to speak to him in one of his last interviews at YOW! Conference in Brisbane.

  • David Hussman’s YOW! 2017 talk “Learning in Product: How Wrong are You Ready to Be?”
  • Extreme Programming Explained” is Agile’s White Album, just don’t read it backwards!
  • We make stuff up in software too much, rather than learning from the past and patterns
  • You can’t look at code and tell it is going to be a good experience and we don’t know our ideas are going to be great until we interact with them
  • The tenth principle – simplicity is essential
  • A good developer needs confidence and war wounds, same for Product Managers – they have shipped something crappy and don’t want to do that again
  • Cardboard User Story Mapping app
  • The Shallot (The Onion’s little brother)
  • Craig’s InfoQ interview with David Hussman
  • Dude’s Law – Value = Why / How, when how equals zero you get infinite value
  • Nonban – the least amount of process with the most real and measurable value
  • First follow the product, then follow the process
  • Product Discovery – you need a discovery cadence and a delivery cadence, we need product engineers as much as software engineers
  • Alan Cooper “You listen to what people say, but you don’t necessarily do it”
  • There is not enough written about how products are delivered well across multiple teams
  • We need more clever visualisations in our tools
  • We don’t need more UX designers, we need more people with UX skills
  • Interactions cut across stories – interaction driven design
  • Chaos engineering – moving beyond resilience to intuition, feels like the early days of Agile, no judgement just people trying cool things

Renee has been busy being sick (and Tony and Craig are sick of being busy) and thus it has been a long time between cough syrup for our Revolutionists…

Episode 124: Talking Testing with Anne-Marie Charrett

16069825102_aa54010a22_zCraig is at YOW! Conference and catches up with Anne-Marie Charrett who is well known in the testing community as a trainer, coach and consultant but also for her support of the community:

  • Don Reinertsen talk “Thriving in a Stochastic World
  • Context-Driven Testing
  • Testing is a verb – it’s a doing thing and not an output, but the challenge is you cannot see doing
  • Anne-Marie’s class in Exploratory Testing
  • Where there is risk and failure, there is a job for testing
  • Exploratory testing – the key is feedback and using the learning to feedback into the next test
  • Agile testing – don’t try and test everything and don’t try and automate everything either, rather adopt a risk based approach
  • Unit testing – the usefulness depends on the programmer and the context and figuring out what you are trying to achieve
  • Sydney Testers Meetup
  • Speak Easy – Speak Easy is a voluntary program designed to increase diversity in tech conferences through dedicated conference spots, mentoring and events
  • YOW! WIT Program
  • WorkVentures – training marginalised youth
  • Testing challenges include microservices (the risk of bounded context and breaking things down and missing the whole) and working together as developers and testers
  • James Lewis podcast “Episode 120: Microservices & The Lean Enterprise with James Lewis

Episode 111: M&Mailbag

peanutmmCraig and Renee, sitting in a shoe-box sized hotel room in Sydney eating peanut M&Ms, decided to rustle through the mailbag and answer a bunch of outstanding questions.

Note: this episode is not sponsored or endorsed by M&Ms but we certainly enjoy their product!

Crossing The Chasm

  • more and more organisations seem to be crossing the chasm to Agile, but too many are still just doing and not being Agile
  • inimal viable product (MVP) is still the trend word, the next stage is Minimal Viable Experience and then Minimal Viable Robustness to Minimal Marketable Product and finally Continuously Evolving Product
  • Enterprise Transformation Meta Model
  • Agile is a true north concept, not sure that you will ever get there

Suggested reading list on where to start with Agile:

What certification should a new Scrum Master get:

Building your own scaled framework

  • Holacracy and Reinventing Organizations
  • need to answer questions around ensuring quality, growing capability, benefits realisation, etc…
  • at what level do the questions need to be answered
  • Minimal Viable Organisations
  • scale on the operational cadence of the problems of the organisation, not following a framework
  • how often do we check that our approach is meeting our needs

Visualising business analysis in a Scrum team

  • 3 Amigos approach
  • call it what it is if you’re sprint length is longer than it is
  • focus more on Kanban flow

Reading List

  • Renee is reading about climate change (and how that applies to Agile) including “This Changes Everything” by Naomi Klein
  • Craig is reading “CTRL-SHIFT” by  Jessie Shternshus and Mike Bonifer
