Episode 127 – Storming DD’s with Paul Rayner

The Agile Revolution Podcast

Craig chats with Paul Rayner, a BDD and DDD expert who helps people bridge the gap of collaborative design between developers and business representatives, at YOW! West in Perth, and two old friends talk about the following:

* Agile Alliance Functional Testing Tool workshop (2011 in Salt Lake City)
* “Domain Driven Design” (Eric Evans) and “Working Effectively with Legacy Code” (Michael Feathers)
* The heart of DDD is about developing a rich model to allow you to deal with complex business domains
* Domain Driven Design Europe conference
* Design done well should pay off immediately, as well as in the medium to long term as well
* There are lot of overlaps between DDD and BDD, particularly the use of an ubiquitous language, BDD is a test first way to drive out your domain model
* YOW! West Keynote “EventStorming”
* Given When Then has…

Episode 124: Talking Testing with Anne-Marie Charrett

The Agile Revolution Podcast

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…

Episode 123: Some Principles of Lean and Product Development Flow with Don Reinertsen

The Agile Revolution Podcast

8265695783_995186c1ce_hCraig and Tony are at YOW! Conference and are privileged to spend some time with Don Reinertsen, who is considered one of the leading thinkers in the field of lean product development and author of numerous books including “Principles of Product Development Flow”

  • Principles of Product Development Flow” book and why there is a waterfall on the front
  • Japanese Manufacturing Techniques was the name before it was rebranded as Lean Manufacturing
  • Taiichi Ohno, the father of the Toyota Production System, hated math and thus preferred to sit on the factory floor and tweak processes, hence it was not a theory driven approach but rather empirically driven
  • Need to understand why things work so you can transfer it to other domains, a big shortcoming in lean manufacturing is that they don’t have much of a mathematical view on what they are doing
  • You can use magic in manufacturing…

Episode 122: Learning to Learn with Aino Vonge Corry

The Agile Revolution Podcast

ainoCraig is at YOW! Conference and catches up with Aino Vonge Corry who is one of our very few repeat guests on the Agile Revolution. She describes herself as someone who puts speakers on stage, makes developers communicate and messes with the heads of students!

  • Part of the YOW! conference organising committee
  • Important to find examples that relate to all of the students in the class (not just a subset)
  • Microservice lectures – no more than 15 minutes lecture and then a learning activity
  • If there is interactivity then there is a reason to turn up to a live lecture
  • YOW! 2015 talk “A Comment on How We Learn
  • Need to respect and acknowledge that other people take in knowledge at different paces, this is important in activities that we give people time to think
  • People need to relate ideas to the things they are doing now to take…

Episode 121: Diversity & Frugal Innovation in Africa with Betty Enyonam Kumahor

The Agile Revolution Podcast

enyoCraig and Tony sit down for a conversation at YOW! Conference with Betty Enyonam Kumahor (stands for good for me, on the way there) who is a technology leader in Africa:

  • Tony and Enyo are mutual members of the Alistair Cockburn fan club
  • YOW! Conference talk “Frugal Innovation and Scaffolding Software
  • Software engineering uptake in Africa is very low, need more technologists because it is is not an industry it is an enabler
  • Lots of diversity challenges in Africa – lees than 1% of the South African IT industry is women, but also diversity in languages, education and belief systems
  • Diversity is a multi-pronged issue, need to be patient but not complacent to move the needle forward, give girls the confidence to be competent and to push the boundaries
  • Frugal innovation in Africa – building technology in a space of constraints such as inadequate power, everything happens by mobile…

Breaking the Cylinders of Excellence (in the Australian Government)

YOW-Nights_Logo_stackedAt the recent YOW! Night in Brisbane (as well and Sydney and Melbourne), Lindsay Holmwood (the Head of Technology at the DTA) presented “Breaking the Cylinders of Excellence”. It was a rare experience to hear the story of how the DTA is using cutting edge development practices to help the government catch up with, and even exceed, the public sector. 

 

  • DTA – aid transformation in government, small agency
  • Delivery hubs in Sydney and Canberra – help identify and plug capability gaps in teams
  • Prototype of how government services could work  gov.au/alpha
  • Digital Service Standard – 13 characteristics on what good looks like in government, useful in organisations as well
  • Cloud.gov.au  – government cloud service, usage growing, continuous delivery pipeline (which is a major change for government who are used to 2 changes per year)
  • The unit of delivery is the team – not about individuals, but the team – borrowed from GDS
  • Government is slow, but government is designed to be stable, they cannot fail, they have characteristics that are resistant to change
  • Myth that organisations must choose between speed and reliability, high performing organisations deploy more frequently, have shorter lead times, fewer failures and recover faster, but they also have a greater profit
  • Want to deliver like a startup but be stable like a government
  • Not a lot of cross pollination between departments currently
  • Read the policy! – quite often the process is not mandated
  • Document what works and doesn’t so it becomes a repeatable pattern – ie. running a meetup inhouse, don’t tell me I can’t do it, tell me how I can run it without being thrown in jail!
  • Stick with technologies the government is comfortable with if you are changing the delivery engine
  • Security matters – prevention is a battle you will always lose, detection is your best defence – aggregate and log in one place, identify threat signatures, etc
  • Embed security people on big services so it is part of the architecture
  • Proactive testing between different governments around the world on similar platforms
  • Simplest security breaches make the most mess – infected excel macros, leaving free USB keys in the foyer that are malware infected
  • Need to put user needs first – alpha mockup using tools like Jeckyll, then beta then live
  • Lots of people strictly interpret the design and delivery guides – they are guides not rules!
  • Create a longer runway by pulling tech forward – turn down the volume of design, turn up the volume of tech
  • If it hurts, do it more often!
  • Fixed cost delivery with agile is a thing, agile is a way to de-risk in the government
  • Don’t put manual testing on the critical deployment path – have special skills on hand for accessibility, performance and security

Episode 119: Agile (Raccoon) is Dead with “Pragmatic” Dave Thomas

The Agile Revolution Podcast

davethomasCraig and Tony are at YOW! Conference and get the opportunity to sit down with Dave Thomas, signatory to the Manifesto for Agile Software Development and have a great discussion about:

  • Dave’s talk “Agile is Dead (Long Live Agility)
  • Agile as a word has become meaningless, don’t follow the off-the-shelf processes, apply small corrections to move forward
  • Story of Stone Soup is like Agile consultancies, the hard work is done by the companies
  • Scrum is a good starting point due to its simplicity
  • Raccoon is a noun, so not a good replacement name for Agile, because you can buy a pound of it
  • 1,000 working on one thing can never be Agile, you have to make enterprises agile before you can run an agile project
  • The values in the Agile Manifesto hold up well, would have been nice to have had more diversity, had no expectation they were…

Social Good and Flying Robots

YOW-Nights_Logo_stackedAt the recent YOW! Night in Melbourne (as well and Sydney and Brisbane), Daryl Wilding-McBride (the CTO of DiUS) presented “What I Learned while Teaching Kids at Flying Robot School”. It was an interesting story on the importance of social good for those of us in the technical space.

  • Waking hours capacity – families, hobbies, paid work, unpaid work
  • Not all work has equal social impact – pays the bills > interesting > impactful > worthwhile
  • Worthwhile work creates a legacy and passes the BBQ test (something you are proud to convey and recognised as value by the other person)
  • 80000hours.org – the average hours you have from university to retirement, help you decide how to spend that time and be effective
  • William MacAskill “Doing Good Better” – how do you know your social impact is not being wasted – doing good, lean
  • Dimensions for measuring social impact – scale, neglectedness, tractability, personal fit
  • A lot of untapped potential in rural areas
  • Interest in science and maths drops considerably between year 6 and year 9
  • Number of girls continuing with maths after year 10 – 21% drop out, and for boys and girls the percentage has tripled over the last 10 years
  • Flying Robot School – started 2014, overcome barriers for rural schools, free program to lower barrier of entry, blend of technologists and teachers
  • Drones are not only fun but are a self contained package that cuts across science, maths and technology
  • Had lofty goals on topics to teach, but had to prioritise to mix theory and practice
  • Other social outlets – Random Hacks of Kindness (RHoK), Code Club, FIRST Robotics, NodeBots, Robogals
  • We have an obligation as technologists to make things better
