How Fast is Your Turnaround Time?

It may just be me but I think that's why they are called "customers"
Excuse me while I gather the virgin sacrifice and assemble the pentagram required to solve your problem
How much of that 48 hour deadline did you waste reading /.
Get back to work!
You have to serve the client who is paying the bills - and we had a very vocal one (Nik*). We had a running joke about the release d'jour. But it wasn't a joke. We literally would push a new build to them every day which contained minor bug fixes. It was maddening! But no one had the balls to stand up to the 800lb gorilla, so the madness continued. As a side-note, they were acting as a beta tester and anyone in the software business knows what that can mean.
What was that exploit again?
You can't talk about Wikipedia's flaws on Wikipedia
For high priority bug fixes, it usually takes 1 to 2 weeks to get a patch out once we determine that a patch is needed.

It depends upon the nature of the problem and the competency of the developers.
If you know enough of the code tree you can tell when first reproducing and examining the failure whether it is a one off mistake or a larger procedural fault.
Single instance stupid errors (doh! moments) can be rectified and put through testing fairly quickly, however if your initial examination uncovered a larger problem then obviously the process will take longer (if at all - consider workarounds).
If the original dev/test team has been replaced over time this becomes a more difficult issue and every bug must go through complete verification simply because the extent or ramifications of the code modification will not be known.
In some instances we have had fixes out of the door the same day an issue was noticed, in others months go by before a final fix is put in place.

I work for a bank so we don't do box software, but our patches have to meet FTC standards and Federal bank standards.
It is uncommon, but not unheard of to have an 8 hour fix. In cases of customer data vulnerability, legislation has been made such that if we are aware of a problem, we have an automatic injunction against us continuing to do business unless the problem is resolved. So when we have a security flaw, our bank stops working untill it is fixed. So yeah 48 hours would have people fired for sure.
Compliance/security are the only two things that can spark a release with less than 72 hours notice though.
But the other day, we got an urgent request from our support team to come up with a decent fix in 48 hours. I think they're a tiny bit unrealistic.
Well, we really can't answer that question with knowing how big the problem is. If it's an embarrassing typo on a dialog box, then 48 hours is reasonable. If it's a windows vista security patch, then 48 days would be unrealistic.

Silver Clipboard: Time Management Tips
It depends on what you're maintaining and how complicated it is. I've gotten fixes out in 2 or 3 minutes. That doesn't mean I'm fast and you're slow, though. "How fast is your turnaround?" is like "how long does it take to write a computer program?" It's hopelessly vague.

Yeah, your turn around time seems good and yes, the customer's request is beyond industry norm.
That might mean one of three things:
One: Customer is being foolishly optimistic.
Two: The entire industry is bad about turn around time, and can, if pushed improve it to 48 hours.
Three: Customer needs it really quick and is hoping to get it quicker by asking. They know 48 hours is well beyond the norm, but are hoping you can do it anyway, because the more time it is unpatched the more they are screwed. They know that if you don't ask, you can't get, so they are at least 'asking'.
Me, I think it is a combination of all three. Customer is being a bit optimistic, the industry is bad about turn around time, and also the customer knows it is a bit optimistic but is making the request anyway in hope you will provide amazingly good service.

Sometimes, customers are unreasonable and if they are, they should be treated with respect and the problem explained to them. Yes, they may be incredulous, but if you hold your ground (if they're being unreasonable), treat them with respect, they will come around.
The fact that the parent was moderated down just shows me that the arrogance, contempt, and stupidity in corporate America is alive and well - especially in IT.
I prefer Flambe as apposed flamebait.
With a little simplification, you have four parameters: Difficulty, quality, speed and available resources. Whenever you fix three, the fourth follows (with some unvertainity). It is well known, that there is a limit on how much you can improve the speed with more resources. So there is an upper limit on speed already. The second problem that difficulty is unknown when starting such a task. There is no fix for that.
So if these people fix speed and available resources, and difficulty is fixed by the task, quality is determined by these factors. Period. There is no arguing with hard, real limits. If they do also want to specify the result quality, then they have to leave speed open. Again, there is no way around that limitation. In fact they should be happy if the team manages the required quality at all in reasonable time. Not all teams do.
Maybe thisn will be an argumentation that is inderstandable for people with a business background. Engineers should already know this.
Software engineering is engineering. Engineering tasks in general have minimal time requirements. Look at structural engineering: Nobody would try to design and build a full-custom bridge in a week. Instead it takes up to a decade, depending on difficulty. And you can generally not speed things up by increasing the team size.
Most ACs are not even worth the keystrokes to insult them. Be generically insulted by this and ignored otherwise.
Overall, we manage to get a 'bullet-proof' patch in about 4-5 weeks (from coding->QA->Build/Packaging->shipment)
Not unreasonable, depending on the size of your release. (How many modules and how many LOC you're changing, the number of change requests or bug reports in the build).
But the other day, we got an urgent request from our support team to come up with a decent fix in 48 hours. I think they're a tiny bit unrealistic.
I think they're smoking crack.
So I wanted to get feedback from my peers: are we doing that bad?
With your regular release schedule, I don't think so.
are our customers being unreasonable?
Yes. That's what they do. If they want a crash development program to get this "patch" out the door that fast, they seriously risk software which does nothing but crash. Really, if they want it that bad, they run the risk of getting it that bad.
You have to ask yourself and your "support team" (sounds more like marketing to me): "Do we wish to ruin a perfectly good reputation for quality and reliability in one hurry-up bashfest followed by weeks of agonizing on-line debugging?" Really, advocate any kind of work-around and risk mitigation response before being pushed into an overly-hasty release that will linger on your reputation like a dead skunk.
Welcome to the Panopticon. Used to be a prison, now it's your home.
A patch (IMHO) is a bug fit to existing code. Given the resources we should be able to get a PATCH out in a week. However, if you need a new version of the software to address the issue. Then we're talking longer development/testing/QA times if which case 4-5 weeks would not be unreasonable. Bugs should be fixed as soon as they are spotted. If their is need for a whole rewrite then you may want to talk to your staff
Ask not what you can do for your country. Ask what your country did to you
How much time do you spend on TPS reports?
The last time I did one I forgot the cover page and my 7 bosses all bugged me about it.
At BSDi, the initial patch (which did have flaws, but it fixed the problem) for the f00f bug was same-day, I believe; might have been next-day, depending on where you're counting from. (Contrary to popular belief, this didn't violate any NDAs.) Now, that was an emergency patch -- it took a while to come up with a patch that fixed the bug without noticable ill side-effects.
We had a better patch later, but the initial emergency patch was VERY fast.
On the other hand, if the initial bug report is "Sometimes the program hangs, no, I don't know when. Maybe every week or two." -- well, that's gonna be hard. Exploits generally have the advantage that an exploit is by nature at least somewhat reproducible, and the hardest part is often getting a reproducer. I've had it take six hours to develop a usable reproducer, and three minutes to develop a patch.
Release time depends hugely on process and procedure. IMHO, an ideal procedure would have some kind of way to get a Temporary Patch out into the field ASAP when there's an exploit.

48 hours is tad bit tight. However, I've turned things around in a similar amount of time.
But, the old adage is true: you get what you pay for:
When faced with unreasonable deadlines in the past, I usually voice my opinion once, and just do the best I can. Your higher-ups are probably already quite stressed at this point, and adding stress to the situation doesn't do anything for your career or theirs. Rather, if you make the point that you're doing the impossible, you might just have a little bit more bargaining power when it comes time for raises.
But on the flip side of the coin, if management doesn't learn, and you find yourself constantly asked to do the impossible, you might want to consider employment elsewhere...

*15 minutes.
It's bad enough that they directly state they're not really testing patches with a 15 minute turnaround, but the fact that they're making mistakes that can be fixed in 15 minutes speaks loudly as well.

In that case, 5 weeks is not enough time for a marketing team to decide on a new name.
Our running joke used to be:
Marketing: We need it real bad!
Engineering: How bad do you need it?
Marketing: <puzzled look>
Engineering: Careful what you wish for... OK, Ops. Ship it!
I made them believe it was a hardware problem!
Engineering is the art of compromise.
Maybe the customer is being unreasonable.
Maybe the developer is being unreasonable.
It isn't possible to determine which from either person's viewpoint. You will ALWAYS think that you're right and that the other person is unreasonable.
Which is why you need criteria for bug escalation. Generating an incorrect response on 1 type of transaction for 1 specific scenario that may pop up once a year is far less important than a bug that corrupts the entire database.
And if your product is considered "mission critical", I would expect a data corruption bug to be fixed within 24 hours. Even if it is nothing more than rolling back the recent patches and re-issuing the previous version.
We generally get fixes for real bugs out within 24 hours, unless the problem is traceable to the OS, the only factor really out of our immediate control. Even then, we do a quick evaluation to see if we can replace the OS function. Over the years, we've replaced quite a few of them, but rarely within 24 hours.
But we know our code backwards and forwards; I wrote the majority of the current codebase myself, and I can generally get to within a few lines of the problem just by a bug's description... the rest is a matter of minutes and testing. This app is very large - comparable to Photoshop in terms of feature count - but it is also very stable after 15 years of whack-a-bug and a continuous drive to make the internal structure as orderly and regular as possible.
It is my observation that the more programmers you have involved, the slower your turnaround time (for everything from bugs to features) will be. Likewise the larger the entity, the slower it will generally move. Almost every layer of management and corporate compartmenting disease will contribute to slowing down the process.
For the apps that I use that I have had the experience of reporting bugs, it is my general experience that bugs often are never fixed at all. One browser, "Omniweb", truly my favorite in terms of features, has bugs that make it essentially unusable for me. Crashing, slowing, lockups and so on - really serious problems. I've reported them, they never were fixed, in fact the software was never updated. Eventually, I just went back to firefox. Then as Leopard came out, after years of doing nothing, they released a "Leopard version" in which, perhaps, I might find those bugfixes if I looked... but as I say, I have moved on and no longer have any enthusiasm for the product. Slow bug repair (or ignoring them) is synonymous with telling your customers you really don't care what kind of experience they have with your software.
Apple, with all their emphasis on customer experience, does this too. They've had bugs in hand for very long periods where they simply don't address them. If your bug isn't something they think will affect a lot of people, it isn't likely to be fixed. I've not yet purchased Leopard, preferring not to catch early-adopter syndrome bugs myself, but when I do, I would not be the least bit surprised to find you still can't refresh a remote share that's been changed by the remote OS; that the wifi differs hugely in compatibility between PPC and Intel hardware; that mail still hoses the sent mail box based on the return address; that shell fonts are poorly rendered; that shell ANSI compatibility is still broken; that the OS still provides locked-up beachballs at the most inconvenient moments; that the OS still puts the wrong things away on the HD when RAM gets tight, and consequently becomes massively unresponsive... Basically, Apple doesn't have good control of their OS, are unable to respond to bugs in a timely fashion, so much so that they triage out bugs based on report counts, and the common patter is that Apple provides a great customer experience. So while my own experience is that bug fixes are important and can be quick in turnaround, here's Apple showing us that you can make a complete thrash out of the entire bugfix issue and still come out smelling like roses. So is a few weeks too long? Probably not, if you have a good marketing department. :-)
I've fallen off your lawn, and I can't get up.
Even if the bug is obvious, it doesn't mean that your fix
1)Works
2)Works correctly for all corner cases
3)Does not have unintended side effects
4)Didn't accidently include some other changes you were working on before, which are not ready for production.
You still need to QA. Attitudes like yours are why the quality of software is so poor.
I still have more fans than freaks. WTF is wrong with you people?
The customer described a program they wanted (to run on an embedded system). I estimated 3-4 months. They asked for 30 days or less. I explained what they'd get if I banged it out that fast - something that would work most of the time and not lose too much data. They then explained that the program would save them over $1,000,000 a month. If it quit working, they quit saving money, but nothing else bad would happen.
So, I saluted and said I'd try really hard for 3 weeks for the first version, then about three months longer for a version that would work all the time. Which is what happened.
Do you know the impact on this customer of not having the fix that soon? Maybe it's worth it to them...
Exploits should be a high concern for any company
Which is exactly why exploit fixes must go through STANDARD QUALITY CONTROL. What the fuck good have you done if by fixing one exploit you introduce ten bugs and two new exploits? I don't care how urgently the customer needs it. I'm not going to give them something I haven't tested. That's insane. If they don't like it they can shop elsewhere.
I work for a large healthcare organization and typically have very fast turn-around times (bugs often get squished within an hour). For clinical applications and other core applications, though, we're much more methodical and careful.
I often explain to the user that I can push changes out immediately, but it introduces certain risks. I then detail the risks they may face, and that if they say to go ahead anyway, at least they'll be aware of what might happen.
At the risk of getting modded "offtopic" I will say what everyone is thinking and take a hit for the team
IS THERE ANY WAY TO BAN THIS ASSHOLE!!!! (pardon the little pun I threw in)
