Speed Kills

Posted by Uncle Bob on 02/03/2009

Ron Jeffries wrote a wonderful blog about how we kid ourselves that there is a tradeoff between quality and speed. Isn’t there?

That depends on what you mean by “speed”. If you mean rushingtogetawholebunchofshitcodedandsortofrunning, then quality is not for you. On the other hand, if by “speed” you mean delivering working software quickly and repeatably release after release after release; then maintaining high quality is your only option.

The first course is that of the adrenline junkie. The hacker stereotype of the twinkie eating cola guzzling nerd who cackles like the Wicked Witch of the West while tunnel visioning into his screen and keyboard. The second course is that of the professional programmer, the craftsman who with calm demeanor and deliberate confidence servers his clients, and his career.

We all feel the pressure to rush. It’s like a drug, really. It feels good to through off the disciplines and justcodeupawholebunchofshit. We get the adrenline high, and we feel as though we are skating on the edge between success and failure, sailing so close to the wind that we’re on the verge of tipping, getting the rush of speed. When we get our code working we feel victorious!.

What we should be feeling is stupid. Because we actually were skating on the edge between success and failure. We should not feel victorious, we should feel shame.

We justify this addiction to speed by telling ourselves that our bosses want us to go fast. We tell ourselves that time-to-market requires that we sail close to the wind. And then we put the needle in our arm and let fly another dose of speed—oblivious to the consequences.

I teach a lot of programming classes in which I give the students programs to write. I tell them that the goal is not to finish the programs, but to learn the skills of programming. I tell them that the code they are writing will all be deleted after they leave. I tell them to focus on the techniques and disciplines they are learning, not on finishing the programs. And yet on Friday afternoon there are always a group of folks who are flailing away at their keyboards trying desperately to finish something that they know will be deleted as soon as they leave.

These people have surrendered to the drug of speed. They need to conquer. They manufactured their own deadline pressure and behaved as if their boss was breathing down their necks.

How do you really get things done quickly? You listen to your grandparents. Remember what they told you? “Slow and steady wins the race.” and “Anything worth doing is worth doing well.” How does a professional craftsman get things done quickly? He/she adopts an attitude of calm, focuses on the problem to be solved, and then step by step solves that problem without rushing, without yielding to the need for speed, without surrendering to the desire for a quick conquest.

When you feel the temptation to rush, resist it. Leave the keyboard and walk around. Distract yourslef with something else. Do not give in to the call of your addiction.

If you want to be a craftsman. If you want to be someone who builds software quickly, accurately, and repeatably. If you want to be someone that your employer respects and values. If you want to respect yourself. Then remember this simple fact. Speed Kills.

    I did exactly that a week or so ago. I found myself in an unmotivated, lethargic state. my initial reaction was to try and find that rush to get me motivated again. i realized, though, that my desire to find that rush would only cause problems in the software – i would have taken the easy way out of a complex problem and causes additional problems in the system.

    instead, i shut my computer down and went home. it was one of three choices: 1) rush and feel the rush, resulting in junk for work; 2) do it right knowing that i probably wouldn’t because i had no motivation, resulting in less than stellar work; 3) do it later when i had the motivation.

    in the end, i know shutting it down was the right choice. the problem turned out to be significantly more complex than i originally thought and my cheap way out would have just caused other problems.

    While it is true going too fast is unhealthy, so can going too slow be unhealthy.

    I worked at a small company with a group of programmers who had the attitude of “the software will be ready when it is ready.” However, the funds for the company were drying up and they had to sell software to stay in business. With the programmers having this attitude, nothing was getting delivered in time for keeping existing customers happy or for getting new customers.

    The company is now a memory.

    Speed kills. But so does the attitude that we can take all of the time in the world.

    The Hero effect, the guy that got the job done by working the whole weekend. Everybody cheers! So now we got something that was created by a single guy in the middle of the night in an rush, most likely resulting in crappy code. No more heroes.

    Now having said that, you can work throughout the night and produce quality work, it’s all in the mind.

    It’s good advice Bob. That rush is exciting. When we think the rush is needed, maybe what is really needed is urgency. Urgency can help keep us on track, and make sure that we work toward to goal without a lot of wasted efforts and an attitude of I’ll be done when I’m done. The professional works without wasted effort in a deliberate and repeatable way.

    We’ve all scene the paramedics rushing through traffic, lights flashing, sirens blazing, but what happens when they get to their destination? They calmly take their gear out and walk into the building. They don’t run because when you rush that way, bad things happen. Great post!

    Brilliant. Thank you Bob.

    Speed kills and it’d be great if there was a faster way than personal experience to teach programmers to take this approach to their craft.

    Any tips for helping team mates adopt this approach?

    Does the group of students on Friday afternoon just succumb to the drug of speed? I don´t think so. There is another drug: the drug of accomplishment, of closure. People want to take home “little boxes” with whatever they did. People to leave tasks unaccomplished. They hate to “live in tentativeness”, in the interim. This is also the reason why agility is hard to adopt for some people: because agility means to not finish (yet). Agility is ever open to change. And that´s what contradicts many people´s striving.

    So how do you convince management of this?

    I have been on projects were the developers wanted to go slow and steady while management was slowly stripping away things like unit tests and pair programming because they say their bonuses and their jobs disappearing. Trying to convince them that writing good code a story at a time would allow their application to be released on time was next to impossible.

    Hey Uncle Bob,

    Okay, there’s not any more coming tonight on my blog. However, I will say this tonight: I think most truly good programmers are more efficient than others. It’s not the speed at which you work – it’s the effectiveness with which you work. JP Boodhoo or Oren Eini, these guys are SUPER effective at coding. They do make mistakes of course, everyone does. But when coding, they’re always thinking about their code and how it’s working together and where points of friction are and so forth. They don’t try to hack something out as fast as possible, but instead they write their tests and try to come up with every possible way to break their system in order to be fully covered by the tests, as well as design their interfaces accordingly to produce the least friction.

    I can’t say I actually asked either of them about this – I just noticed it in their various podcasts/vodcasts/whathaveyoucasts. For example, people call Oren Eini (Ayende) a robot. That’s simply not true. He is so effective and efficient at writing code that it seems like he’s going way faster and ALWAYS knows what to do. Instead, he’s just thinking about the programming while doing it, I suspect, as well as writing the tests which help him decide how he really ought to be doing it.

    In conclusion, it is my assertion that effectiveness and efficiency are far more important than speed of delivery, even if it means being late on a deadline.

    I’ve remembered your post from 2007: Going Fast

    IMO, a lot of people miss the point that they should build abstractions. Some people just hack down gazilions of code-lines per day, and go home with a feeling of super-hero-productivity.

    We need less coders, and more anti-coders.

    I’ve learned from experience that what you say is correct, assuming you find the right balance; but I’ve also found that it’s a lonely avenue in most companies (at least the smaller ones).

    I worked at one small company where the main programmer could get a buggy version running very quickly, and looked like a hero. Then, I would spend most of my time fixing his bugs, and looking like I couldn’t finish anything myself. Management never knew the score, and the other programmer was unable to change.

    My last job was similar. I took longer to get projects promoted out of integration to QA, but once they were out, they didn’t come back nearly as often, so that in the long-term, I believe I was as fast as some of the others, and my code didn’t have many bugs once released. Plus, of course, I was having to work around or fix bugs from other people. But I still had a reputation for being too slow, and in fact, I’m now out of a job.

    So, unless you are a very good advocate for yourself, and keep good records of your production vs your coworkers, you will have a hard time practicing many of these principles in a lot of jobs. Management has the attitude “write high quality code with no bugs, but get it done tomorrow.”

    I’ve recently been involved in a project where they have been rushing features to market for a long time now and as a result the code-base has extremely poor internal quality. The questions I’m trying to tackle now is how to justify the investment needed to drive up the quality of the code-base. My gut tells me we need to take a little more drastic action than what Ron proposes in his post (I may be wrong). My challenge has been trying to justify that investment. What costs are there to the low level of quality we currently have that would go away or be reduced by focusing on improving the quality level? Or stated another way, what benefits would we realize by investing in the quality of the application in a significant way?

    I tried to organize some of my thoughts on this over here:http://geekswithblogs.net/Optikal/archive/2009/02/09/129299.aspx

    Well I do understand your point of view, and a good pace might be sign of craftmanship…. on the other hand i find a lot of colleagues lately trying to get the specs and design right 100% taking all the time. In the name of quality… While i more and more find myself leaning into the movement of build a prototype and have it evolve, which is the fast way to build something… Behavior driven development style for quality control…

    While this might not match your idea of fast vs slow, most of the people of ‘the other group’ did told me that i was going to fast , which made me link it to this blog… i think that just stating that fast development is not inline with quality is a bit of going short

    Try telling that to CEOs who don’t get that quality will produce far better ROI than a hack job.

    I too am sick and tired of Managers who promote Code & Run environments then blame it on the lame “business needs it now, or head honcho says he wants it” when the head honcho is WRONG to force this kind of environment and atmosphere within the people they hire to create working and reliable solutions. That is one of the most stupid things you can do to a development team and the product they create for you. That’s why good developers LEAVE and that’s what has made our industry a pile of shit to work in. That’s why the business FAILS. That’s why everything is CHAOS in your department. I’ve seen this over and over.

    Good development teams know that iterations are key and sticking to the plan is key. And sticking to priorities is key. If a stakeholder wants to interrupt the plans, then you can’t expect now x AND y to be done at the same time…that’s just CHAOS. Sorry, but you have to say NO sometimes to the business and reorganize the deadlines have to be adjusted and YES that means some things are pushed out. That’s common sense.

    Pride should be having a sane department, sane and prioritized goals, sane deadlines and development standards which means you do not rush to put out a hack or purchase a 3rd party system because now you are still running and you can’t say no to slow the business down a bit and now you’re buying all 3rd party to get things done at light speed. That shit will fail faster than you can believe and you’ll be paying costs all over the place as well as adopt a shitty API most likely that you cannot extend. That’s the result of RUSH.

    You are saying you’d rather pay for bugs at a higher cost later than test now and add in time to test with a realistic good deadline, and code a decent quality code base that can maintained, extended easily, and which works well for your customers. That’s what gives back to the business, not a hack job and not a burned out IT development team who humanly cannot meet 5 deadlines at the same time due the the fact that when every day or week you introduce a new project add a shit ass deadline that interrupts what they were currently working on but you still expect both to be done? Common. Wake up.

    I as a developer never wanted or felt the need to rush…I don’t enjoy fixing or maintaining that kind of code later and I will certainly not work until 2 am based on lack of structure and practices. So I do not agree that all good developers want to rush… In fact they slow to build solid code and that is how you support your organization effectively.

    Same here Terry. I’m not a developer myself but when I’ve outsourced such work I’ve always emphasized that the developer spends a it more time to build solid code, even if it costs me more.

    Great discussion. My additional 2 cents: 1) I find much more accomplishment in the numerous completions in getting each unit test to work. 2) Until management expects unit test coverage and velocity tracking as part of the software delivery process, then that team effectively has no software processes in place. Consequently, that team is at a continually-increasing risk of delivery failure/increasing bugs over time.

    Totally agree with the post. If you want it done the right way then you need to set a side enough time between then and the deadline. Companies who promote this type of work atmosphere are not getting the quality work they hired their employees to do.

    Developers don’t realize the long term consequence for trading speed to quality because bad quality code can make you suffer in the longer term development process and cause development to take slower and slower reducing the speed.
