Why Buggy Software Gets Shipped 422

Posted by Zonk from the life-is-pain-princess dept.
astonishedelf writes to mention an article in the Guardian about the hard reality of why buggy code is sold on retail shelves. From the article: "The world's six billion people can be divided into two groups: group one, who know why every good software company ships products with known bugs; and group two, who don't. Those in group 1 tend to forget what life was like before our youthful optimism was spoiled by reality. Sometimes we encounter a person in group two, a new hire on the team or a customer, who is shocked that any software company would ship a product before every last bug is fixed. Every time Microsoft releases a version of Windows, stories are written about how the open bug count is a five-digit number. People in group two find that interesting. But if you are a software developer, you need to get into group one, where I am."

        Nonsense. Every major open source project has a complete list of bugs for all versions of their product for all to see, usually right on their Web site, which you can read prior to downloading. For instance, if you click on the Release Notes for Firefox, linked to from the front page [getfirefox.com], you'll see not only a list of known issues in the current production release, but there's a link to their Bugzilla database so that you can read bugs that have recently been filed against it.

        If people would really not buy a software product if they knew about all of it's bugs, then why would they download and install any open source applications? Because they don't have pay for them? Just because you don't pay for a piece of software, that doesn't mean it costs the user $0 to install and use.

      "How about making a list of known bugs available to your customer prior to purchase?"

      There are several reasons not to do this. Not the least of which is simply that most customers don't want to know what's going on inside the application. They want to click "Button A" and have "Box X" pop up and start flashing - or whatever. They don't know that 300 lines of code went into making that happen and they're fine with not knowing that. They certainly don't want to be forced to actually understand what each of those 300 lines of code are doing. Try to explain it to them and watch their eyes glaze over in a hurry. You can try to simplify the explanation for them, but it'll never be enough because they can't grasp the problem without understanding what goes in to making it work; a necessity in understanding why it doesn't.

      The point is that when you get into listing bugs, you have a number of caveats. First of all, in their eyes, you're telling them that the application you're selling them is broken. Sure, those bugs may never actually affect them. They may even be in parts of the code that aren't even used yet because it's part of a feature not currectly activated. But hey, you're selling them a broken program. Remember the Pentium floating point fiasco Intel had to suffer through? What was wrong with their processor? Nothing that isn't wrong with anything ever manufaturered: minor defects that rarely or never manifest under normal operating conditions. What happened when the news got out about the floating point bug that didn't affect more than a hundreth of a percent of buyers - if that? The 'public' went ballistic about it and Intel was eventually forced to do a recall of CPUs that were perfectly functional. Nevermind the fact that AMD and Intel routinely publish a long (and growing) list of 'errata' for their processors that are chock full of bugs. The moment the public got news of a single errata (which, again, didn't even affect them), they demanded replacement "working" products. Are you, as a company, going to expose yourself to that kind of liability?

      Basically, the customer doesn't understand the inner workings of your application, doesn't want to understand the inner workings of your application, and if you try to make them understand anyway, bad things will likely happen to you. People can handle unexpected behaviors (bugs) when they're discovered and a promise is made to make it right (patch, updates, etc). But if/when they get wind that you knew the bug was there, and that there were others? That's a receipe for disaster.

      What geeks/coders need to understand is that we make up a vastly small minority of software users. Unless and until a vendor is selling products to, and only to those who are informed, knowledgable, and intelligent about computer code, you will never see a list of known bugs right on the box. If it's there at all, it'll be made as obscure as possible so that your average Joe can't find it. Why? Because average Joe will go nuts regardless of how inconsequential the bug is, or how much it would push back the release of the product to stamp out all the (known) bugs.

      Personally, I don't blame developers and vendors one bit for obscuring the known problems. When I run into a bug in something like MySQL or PHP, I can find out about it, whereas slightly-above-average Joe (beginner PHP page creator) would have a heck of a time. I find that to be ideal, as I can find the information I need and Joe's not taking up the vendor/developer's valuable time whining about 10,000 bugs he'll never see in his life.

      Reading this made me cringe:

      "All the reasons are tied up in one truth: every time you fix a bug, you risk introducing another. Don't we all start out with the belief that software only gets better as we work on it?"

      Holy shit! I can't imagine being on a team with that attitude? Do you people write tests? There are dependable ways of insuring that changes don't re-introduce old bugs, and if you can't fix one thing without causing a seemingly unrelated problem, you're working with some pretty smelly code.

      There's definitely truth in the statement that the need to use software and the need to eliminate bugs can be at odds with each other once the bugcount is low enough that the product is usable. But... isn't that obvious? How many open source projects out there (without version numbers approaching a known irrational number that is...) can really brag of being bug free?

      BUT this article is a good reminder of why I'm glad the boxed-software days are coming to a close. Software should either be written with a client present or by people who intend on using the product themselves. Trying to come up with a featureset for some vague "target market" is a horrbile way to write software. Software is unique because it is both engineering and design at every phase of its creation... and without set feature requirements and feedback, there's really no way to know if what you're making is well engineered or not. Anyway, don't work in a closedsource / many customers environment... it's bad for the brain.

    The argument about the enormous bug count in Windows isn't really about every last bug being fixed. The article fails to address a separate question: whether you're allowing the public to do your beta testing for you.

    The idea of QC/testing/beta/whatever the heck you want to call it is that you get as many bugs as you can fix while accepting the ones that will remain behind. That's absolutely correct. However, there are companies - like Microsoft - that are notorious for either being sloppy and not getting bugs they should have, or just straight up not caring at all and rushing a product to market that legitimately shouldn't be there.

    The argument can even be extended to good coding practices, like worrying about security fron start to finish rather than after you've entered beta (another well known Microsoft flaw, though they're getting better at it). That reduces the number of bugs to begin with, which in turn gives a better product.

      I'm surprised I had to read so far down to find this, the real reason. Stuff gets shipped because somebody needs to make their numbers, now. Sometimes the survival of the company is at stake, and sometimes it's just an individual climbing the career ladder.

      In a previous life I was in charge of software development for a smallish company whose business was scientific software and systems. To my repeated horror, the CEO and the Sales & Marketing VP would get together and decree - perhaps for reasons that were very compelling to them - that major software packages would be released to customers with no testing whatsoever. Stuff went straight from the compiler to the customer, sometimes even without a cursory walkthrough of functionality. For objecting, we, the software people, were branded as troublemakers and criticized for not being "team players". Once labeled in that way, I would be pretty much ignored any time I had to report that a new product or an update was not ready to ship. Needless to say, I left that company in a hail of bullets.

When I was the lead tester for DBZ: Buu's Fury GBA at Atari, the producer revised the schedule without informing us and I didn't find out until two months after that happened. On top of that, Nintendo insisted that we put in wireless multiplayer capability because the title was coming out the same time as the new wireless adapter was being released. That was a disaster in the making since the wireless API was unproven (even Nintendo had a hard time with it), we didn't get the wireless adapters until a few weeks before we were supposed to code release, and I was planning to leave the company because my boss thought I wasn't working hard enough (I worked 28 days straight before I left, BTW).

    Because, by and large, no one gets killed when commercial software crashes.

    In those cases where it does; e.g. medical/aviation software, usually embedded people take the time. If aviation software designers cut the same corners (w.r.t. bugs vs. features) that office software designers do, planes would fall out of the air and people would die. So they write well engineered software, in well engineered, fault tolerant languages (lika Ada). (Yes, yes, Ariane, but thats the exception that proves the rule)

    The real reason buggy software is shipped, is because buggy software is accepted by the market, and people will keep buying it, and continue to roll their eyes when it crashes, because they're completely inured to it, and many of them have reached the conclusion that its literally impossible to write robust, stable software.

    I work for a large software shop. In my experience it boils down to:

    1. Accellerated schedules created by management / client without development buy-in.
    2. Management cutting development phases in order to get things done faster to meet dates from #1. (i.e. design reviews, code reviews, phases of testing, etc)
    3. Shipping portions of the development off to India teams (in order to save money) who are under trained, and can't speak the same language as the other developers, and who won't ask questions when they don't understand.
    4. Giving development / design tasks to people with no experience in the subsystem that they are being assigned to, because management believes that one developer is as good as any other... we're just bodies...
    5. Churn in employees... Better / more experienced people leaving for better jobs, and noobs coming in to replace them. After a while, you have too many noobs, and not enough older, more experienced folks.
    6. Colleges not training people on common coding errors, proper design principles, good design patterns, proper testing and documentation strategies, etc.
    7. The old addage: Too many cooks spoil the broth. Some times, there are too many senior developers, architects, etc. workign on a design, an they all have their favorite ways of doing things. Many times, even within a single subsystem, one senior person will move to a new project and a new one will come in, and want to change the process / design to fit his style... and usually at the last minute...

    Now, as to why bugs don't get quashed quickly:

    1. Lack of enough informatin from the person experiencing the problem to allow development to recreate the problem.
    2. High complexity of the systems involved.
    3. Bad library design / separation of concerns / encapsulation, etc. means that a small bug in some unrelated libarary can cause problems where you never expected them.
    4. Developers who aren't experienced enough with the code / subsystem to be able to find said small bugs. (i.e. see number 4 and 5 from last list).
    5. Developers who aren't given training and experience in the proper use of debuggers, memory checkers, etc. (how many college hires out there really know how to use dbx to track down a bad pointer in the free list?)
    6. Too small a staff, too much to do.

    Group 3 consists of people who acknowledge that fixing all bugs is impossible, and that judgement is necessary in deciding which bugs need to be fixed... but nevertheless contend that within the personal computer software culture in the United States, these judgements consistently err in the direction of shipping software with too many bugs.

    The personal computer software culture in the United States is much like that of automakers in the United States circa the sixties, who insisted that the low quality of U. S. autos was the result of the best and wisest judgement... and that public toleration of low quality, as reflected in good sales and profits, validated their judgement.

  • The internet makes patching software a breeze.

    Do you remember back to a time when virtually NO software / games had major bugs? Yeah, that's because patching software by snail mail with floppy discs was a costly and unpractical nightmare, so you had to get it right the FIRST time.

  • One thing which immediately struck me was that the author seems unaware of a key software engineering principle: Reducing design complexity reduces the number and severity of bugs. By now, we all know that there are tradeoffs between complexity, time, and features. However, all other things being equal, some people and organizations consistently produce better software than others. Consider, for example, Linux and Windows. The key reason Linux is more stable and more reliable than Windows is that the process which produced Linux is inherently better at catching and correcting flaws than the one used to produce Windows. Anyone who has ever had to commit a patch to the kernel team knows that design changes are thoroughly vetted before being accepted into the source tree.

    Even I have completed some rather large projects without a producing a single bug. It wasn't a matter of coding skill, but rather, that I designed the software such that:

    • It was broken into modules with clean interfaces, so that each module could be independently tested and verified.
    • It was designed such that a bug in implementation would be apparent immediately (i.e. - it would crash).
    • It was designed to accommodate the inevitable change in requirements.

    Even very complex software can be written virtually bug free if good software engineering principles are followed. Something as simple as adhering to the Unix design principles [faqs.org] can drastically reduce the number of bugs in a shipping application.

    Generally speaking, the old adage about "failing to plan is planning to fail" holds true with software as well. The core idea behind software engineering is that quality is improved not by doing more testing, but rather by improving the process by which software is written. Consider the following two, widely used approaches to software:

    1. Define the requirements.
    2. Design the software as a large, monolithic application with numerous interdependencies and no clean interfaces.
    3. (RE)Write the software.
    4. Test for bugs.
    5. If bug found, goto step 3.
    6. Marketing promises something engineering can't deliver. Requirements change; goto step 1.
    7. Customer complains that feature X isn't implemented. Requirements change; goto step 1.
    8. Marketing adds features to product brochure. Requirements change; goto step 1.
    1. Define the requirements.
    2. Partition the requirements into easily tested modules separated by clean interfaces, anticipating the need to add future functionality at a later time.
    3. Design each module.
    4. Write the module(s).
    5. Test the module. Bug found? goto step 4.
    6. Marketing promises something engineering can't deliver. Requirements change; goto step 3.
    7. Customer complains that feature X isn't implemented. Requirements change; goto step 3.
    8. Marketing adds features to product brochure. Requirements change; goto step 3.

    With the second model, changing requirements do not require a complete rewrite or complicated analysis of the entire system. It is a flexible model. The key problems is that it is a hard sell - the design requirements phase takes more time, but it ultimately provides the flexibility that management and marketing require.

    One of these models addresses the fact that requirements frequently change; the other does not. One of these models takes into account the fact that complexity is hard for a single person to manage, and one does not. One model limits the amount of damage that a single, bad coder can inflict, and one does not.

    Yes, we may not fix every bug, but we can at least use sound design processes to minimize the impact of bugs. BTW, the fact that Source Gear can't interoperate with other databases is not merely a bug, but a design flaw. Had it been properly designed, using a
