No time for that, I’m seriously late. I was leaving the office just as someone said “James, before you go…” and that was the end of any hopes I had of getting here on time.
It’s 6:40pm, I’ve finally got my sh1t together, and we’re off! In act that’s a lie, they were off ages ago. I’m so late there aren’t even any seats, so I’m sat in the corner at the back, like a proper Billy No-mates
6:41pm: Chris is talking about big balls of mud and how they’ve gone from that, to a much smaller ball (no mention of mud this time).
6:42: Slides are going by quicker than I can type! Chris is talking about the importance of moving away from a “blame culture”. I personally hate blame culture, I think it was the French who invented it. Arf! (sorry).
6:45pm: Ok, there’s a slide on how to get to Continuous Delivery, I’m going to pay attention to this one…
It says you need:
- Cross functional product focused teams
- A focus on technical debt
- Sit the team close to their clients
- actively remove blame culture
- focus on self improvement
- radiate metrics
- collect metrics on work in progress
After a quick coffee break it’s time to interrogate the suspects – It’s Q&A time!
7:01pm: How do you share “commonality of functionality”? Asks someone who likes words ending in “ality”. Service oriented architecture was apparently a big help responds someone from the 7digital posse (they are a posse by the way Chris has been joined by some 7digital reinforcements).
7.02pm: The next question is about metrics and how they collect them. Apparently they’re working on a logging system, but I’m guessing they also use CI and some live reporting tools which I probably missed in the earlier slides! Oops.
7.05pm: “What didn’t work?” Asks someone (my favorite question so far. I’m giving it a 7.5 out of ten). Trying to patch things up didn’t work. The dependency chain caused a pain. Acceptance Tests were a pain (haha!) Using UI stuff and a shared DB caused Acceptance Test issues, they say. I nod in agreement.
7:07pm: Someone says something about keeping environments the same being a challenge. They’re meant to be the same??? Where’s the fun in that?
7.10pm: A question on blame culture is next up, namely “How do you get rid of it?” By not telling on people! Also, having a dev manager who protects from above is handy.
It’s how you respond [to blame] that’s important, as that’s what sets the tone.
7:11pm: How did you make the culture change? Asks someone who wants to know how they made the culture change. It’s another good question, and one I’d really like to learn from. It’s all very well having a great culture, and there’s no denying its importance, but how do you make a culture change if it’s not ideal to start with? Sadly the answer isn’t straightforward. The posse reply with things like “Adopt Agile principles”, “tech manifesto” (which sounds cool), “self-organising teams”, “small steps” and “leading by example”. Followed up with “hire well”, “you need champions!” “do workshops”. Also, “the CTO is pretty cool”. Hmmmm, so no “click here to change your culture” button then?
7:16pm: The next question is a corker. It went a bit like: “Usually have to change architecture of system to support Continuous Delivery, but also sometimes the architecture of organisation as well. Did this happen?” That’s the winner so far. “No” comes the answer. Damn. At 7 digital there’s a focus on lack of hierarchy, so quite a flat structure. Not much change was needed then, obviously. I think the word “culture” came up as well, and not for the first time.
7:18pm: How have they managed to integrate Ops, asks the next person, clearly fresh from devopsdays. “We’re still learning” is the honest sounding response. Not that the all haven’t been honest sounding. They’ve started assigning Ops people to “the team”, by which I assume they mean the project team.
7:20pm: Someone wants to know if they had a shared goal between tech/ops and dev? I think the answer is yes. Basically Rob (who is the head of both ops and dev) became head of both ops and dev, which helped. He also created a tech manifesto and is toying with the idea of putting up some posters. When I was a kid I had a poster of Airwolf in my bedroom. Not sure if that’s going to help anyone though.
7:21pm: “Is there a QA on the team?” is the next question. Yarp (I’m paraphrasing). But the QA person is more of a coach – everyone is expected to do it, but they’re there to lead. No separate dev manger or QA manager – everyone’s one great big team (aaahhhh).
7:23pm: Somebody has asked how they handle support, and whether there’s a support team. I think the person who responds says there’s a “Systems team”, who get a text or call in the middle of the night. It seems a bit cruel that they wait until the middle of the night to text them but what do I know? Apparently the devs may also get involved, so that’s ok. There’s an on-call team, “but this is an area for improvement” they confess. Mainly it’s a case of “call someone!”, which I personally think is pretty good. But they do stress how there’s a focus on monitoring so that they can catch as many issues as possible before they become, er, issues, if you catch my drift. They said it much better than I can write it.
7:26pm: “How frequently did you deploy your big ball of mud compared to how frequently you do it now?” And that question goes to contestant number 2. It used to be one every 3 months, but they don’t measure how frequently they can deploy stuff any more because it’s that frequent.
(that’s just showing off). Improving the deploy mechanism was all-important. And changing the culture to shift to more frequent releases. That word “culture” again.
7:30pm: This question sounds like a plant: “How do you have time to test stuff if you deploy so often?” asks some cheeky 7digital employee hidden in the audience. I’m joking of course, it’s a nice question because it leads to a well executed answer: Chris basically explains that because they deploy so often, their releases are very small. Also, they’ve automated the hell out of everything.
7:31pm: Dave asks a really good question but I’m far too slow to keep up! It included the phrase “separation of concerns” so was probably too complicated for me to understand anyway.
7:40pm: There’s a question about schema changes. I reckon the answer will include the word “culture”. it does. Somehow.
If there was a word cloud for this Q&A session then “culture” would dwarf all the others. Something tells me that “culture shift” is important.
7:45pm: “How do you manage project accounting?” “We don’t” – No mention of culture!
7:46pm: Someone asks “If there’s a production issue, like an outage, who takes ownership?”. Nice one, who indeed does take ownership? “Everyone, we have a culture of shared ownership”. Gah! it’s all about culture!
7:47pm: “How do you decide what projects get green lighted?” asks some poor innocent from the back of the room (and no, it wasn’t me). Apparently this has nothing to do with Continuous Delivery (and all the other questions have?) and there’s nobody from the product team here so that question lands on stony ground.
7:52pm: Banos treads a fine line by asking a question dangerously close to the time when we’re meant to be heading to the pub, but just about gets away with it “what CI system do you use?” he asks, and the answer is (drum roll…..) Team City! Actually there was no drum roll, I made that up. Then interestingly they say that everyone is in charge of looking after Team city and that they just trust each other! Crazyness!
8.02pm: “I was told we finish at 8” says Chris, and she’s bloody well right, there’s a pub nearby and some of us are thirsty.
So, in conclusion, 7digital know their Continuous Delivery from their TDD, and “culture” is the word of the evening. I’m off for beer with Banos, and the rest of the London Continuous Delivery gang!
