PAINFUL Software Release Cycles Are NO JOKE

What’s your software release cycle? How long does it take you to prepare for a release? If it’s more than a day you aren’t practising Continuous Delivery yet. Still, there are all sorts of barriers to optimising the release process that get in the way of effective, efficient software release management and the adoption of Continuous Delivery. CD fixes release cycle problems by optimising for fast, efficient, cycle times and high-quality outputs, but how do you get to there from where you are now?
In this episode CD expert Dave Farley describes the Software Release Death Spiral, how decisions reinforce bad outcomes, and amplify our need to do more things that only make releases more difficult and more risky. He describes a real-world example of a large company, with complex software, breaking out of this death spiral and how they went from being unable to release software at all, to releasing software all the time.

12 minutes in and this man is describing the exact problem with my job in ever more painful detail. I work in a large cybersecurity company that sells my hours to a government agency through contracts (yes the same government agency through sometimes five different contracts at a time) that specify projects. The relationship with the customer is cold, on some projects hostile. The product suffers too, of course. If we find a bug we first ask who has to pay for it, us or the customer, then distantly second whether it matters or would be easy to fix. Releases are three a year at most. But we are certainly agile, my boss says, because we have scrum and sprints and a scrum master who spends most his time working on charts and estimates. It's not all bad. At least we have decent testing (though mostly manual) and support for me learning the skills to get a better job later on.

@BryonLape Жыл бұрын

I'm betting what they mean by "Scrum" is what some certification mill taught them, not the framework PDF. Either way, Scrum is agile nor does it work. It is a pretend exercise to create shiny reports to show upper management.

My job wasn't in a gov't setting like this, but it was very similar. Same kind of relationship w/ the customers, a toxic relationship between support & developer teams, and many outages. The dev teams had some sort of scrum team structure. Managers focused a lot on tons of metrics & estimations, yet we never delivered on time and with many bugs and the metrics were most likely skewed. The business was sold to another company and is apparently the product I was working on is now in the process of being shut down now by the new company. The development effort was soo slow and poorly done that I had to resort to running manual MySQL commands in production and shell commands to modify database rows for a customer. Scared the HELL out of me. Sooo much stress, I QUIT! Gave me a lot of experience on exactly which type of company to look out for when it comes to finding agile farces.

Great description of a rare event. This is that eventuality where a team of devs plus manager cannot be corrected but are replaced by devs and manager who can. How do the new team members undo the evils of their predecessors. The more normal eventuality is that the devs and manager immune to being corrected (such people do exist) are unable to get new jobs easily and stay put forever, perpetuating their outcomes.

There are some orgs that won't change. This is certainly true, and it's also true that when you start trying to change orgs like this you can activate the "cultural anti-bodies" who will aim to retain the, non-functioning, status-quo. But it's also true that if you never try change will never happen, and many people, even in dysfunctional orgs want to change. There's a joke that I have heard Martin Fowler tell a few times, "You either change the org where you work, or you change the org where you work". For me giving up and not trying to change things for the better isn't an option, but sometimes the scale of the change that you can make may be small.

I totally agree. I won't ever try to change an organization on a fundamental level like that again. I'll always discuss w/ direct co-workers, but it's not my job to convince the entire org. Don't "fix" or save them. What changes is how much money they get. Just let them go broke and stop earning them money.

Been there. It's a paradoxical situation on many levels. Part of the processes are cemented in contracts. Contractors would deliver the code but no unit tests (no contractual obligation). Bureaucracy is superfluous if you version your documents, code, etc. anyways. The bureaucracy could still not make sure that changes to the software or infrastructure were documented in a transparent and easily understandable way. Still important details are not always documented. The various teams are opaque regarding their responsibilities and if they are not then people in other departments don't care about the big picture. Division of responsibilities is on a very small scale thus introducing continual delivery would involve several departments and teams. But still quite a few essential requirements are missing (i.e. unit tests and automated tests). Tests are semi automated although it would be possible to "go that extra mile". The organisation spends a lot of money on professional "toys" with excellent automation capabilities (e.g. weblogic and jython scripting tool) and a lot is still done manually. Deployments are done partly manually and almost every time something goes wrong. It's complicated on many levels.

@ContinuousDelivery Жыл бұрын

@@PavelHenkin only bad managers dislike being told they are wrong 😉 It isn't the managers job to tell everyone what to do, though many try and arrange things to work like that. Good managers are more like sports coaches, they set out the strategy for the game and help the "players" to maximise their skills and to understand the strategy well enough that they can exercise freedom to improvise as the game progresses. As an engineer, your job is to produce good SW that solves a problem for someone as efficiently as you can. Some, quite a lot, of that, only you can do. So properly understanding the constraints in which you operate (regulation for example) allows you to better optimise to minimise the impact pf the regulation. Leaving that as a problem to non-technical people means that you will get non-technical (read 'bureaucratic') solutions to these problems which are actually VERY amenable to automation. You have to engage with this part of the problem, with the help of non-technical people, but not at their command. I describe some aspects of this in this blog post: www.davefarley.net/?p=285

@ContinuousDelivery - Do you think that company would have been as accommodating to your ideas if you had been an employee, say someone who read Continuous Deliver, watches these videos and/or took your course, rather than an external consultant? I've found it very difficult to make changes from within. The ideas from external consultants seem to carry more weight. The more expensive the consultant the better. And if they have to fly, well then gosh darn it, we're going to jump on this immediately. "And he (Jesus) said, 'Truly, I say to you, no prophet is acceptable in his hometown.'" - Luke 4:24.

@ContinuousDelivery 11 ай бұрын

It is certainly more difficult to make changes like this as an employee, that isn't right, it isn't sane, but it does seem to be a real thing. I confess that as I have become more experienced as a consultant, and higher-priced, it does make a difference to how people listen to me, and who listens to me. The higher the price, the more senior the audience. None of this is good, but the cognitive bias of "decision from authority" is a real effect. I recommend to my clients that they use me for that 😉

A couple of notes from my personal experience: 1. If your estimate is 10 and you declare 40, the team will take the 40 number as an anchor and will fill it with what they consider necessary activities. Then you will likely spend 160. 2. With more or less awareness, both implementers and users recognize the problem of the long delivery cycle and create alternative delivery conduits. Frequently, they use the term "configuration" to create code delivery shortcuts. In reality they build a way to late bind code, escaping the tedious gates of the longer process. This approach creates a full domain of new problems.

it's truly poetic that you made this video when you did... because we just had a bad release... thanks to me lmao.... but on the real, I found a neat new nuance with aws AMI's and time zone persistence when an EC2 is spun up... no big deal, only caused a few 1000 medical records to be written in UTC time instead of central. lol. Given, I'm not ignorant lol, I did test changes made, no one thought to actually look at the ec2 though, since the image pipeline appeared successful based on the logs. It was embarrassing causing several people to context shift in the middle of a sprint, but tbh its this weird nuance experience that I love lol
