The Truth About Last Year's Xbox 360 Recall 255
chrplace forwards an article in which Gartner's Brian Lewis offers his perspective on what led to last year's Xbox 360 recall. Lewis says it happened because Microsoft wanted to avoid an ASIC vendor. "Microsoft designed the graphic chip on its own, cut a traditional ASIC vendor out of the process, and went straight to Taiwan Semiconductor Manufacturing Co. Ltd., he explained. But in the end, by going cheap — hoping to save tens of millions of dollars in ASIC design costs, Microsoft ended up paying more than $1 billion for its Xbox 360 recall. To fix the problem, Microsoft went back to an unnamed ASIC vendor based in the United States and redesigned the chip, Lewis added. (Based on a previous report, the ASIC vendor is most likely the former ATI Technologies, now part of AMD.)"

Years before the xbox360 has been released ATI was already announced as the system parter for the GPU. No "secret unnamed ASIC vendor" anywhere.
The recall, again, was thermal problems.
Do you really think a completely different GPU by a completely different company could have been designed in a year _and_ totally compatible with the original one?

Speculation that is well known to be false and could've been showed up as such with a quick look at the XBox 360 specs which are available in many places that I'm sure Google would oblige to discover.
The issue has already been outed as being to do with cheap solder iirc that simply couldn't stay put under the heat of the system over extended periods of time.

Engineers aren't stupid, and you can certainly cross-train one to do another's job. But you aren't going to do that overnight. If your product is overbudget/behind schedule/etc, you don't want to make it into a very educational failure by regularly having people operating outside their expertise.

You can have business savvy and technological expertise, but it's a roundabout path through today's educational system if you're not teaching yourself at least one. And I think we all know the proportion of people who are capable of serious self-education.

I don't think you're getting it. Cutting costs is one thing. Cutting corners is another. Cutting costs is fine, but cutting corners implies the product is worse off because of it. Few engineers would say "It'd be cheaper to roll our own graphics chip," because they realize the immense technical challenges involved. Few MBAs are likely to understand that, however.
There's a big difference between what you just said and what the OP said. Nobody said MBAs can't be tech savvy. However, the fact of the matter is, most of them aren't.
Also, just to be pedantic, having an MBA has little to do with having business savvy.

Only when problems hit critical mass do they start asking the important questions and gather acurate data.
I've seen groups crushed and the politicians move out before the axe falls. The problem is, they led the charge straight to hell and only got off the bus at the toll charge.
The trick is to yell louder then anyone else when problems are brought up. Scape goats are quite handy too.
I recommend keeping a portfolio of dirt so when it is time to jump ship you point out all of the other rats. This is of course only useful to the guy who is jumping ship. (please take note MBAs as this information is critical to your continued success)

Bunnie's point is that the bga joints cracked over time. Different materials expand at different rates when they heat up, the coefficient of thermal expansion [wikipedia.org]. The fiberglass motherboard expanded at different rates than the silicon/epoxy cpu and gpu. Since the Xbox overheated, and was poorly engineered (so Microsoft could beat the PS3 to the market), the motherboard warmed up, and expanded at a different rate than the cpu soldered to it. As a result, the solder joints were under stress, and thus cracked. You can see this in the red die that leaked between the solder pads when Bunnie pried of the cpu.

Are you telling me that Intel, AMD, ATI, NV, etc. have never released a flawed chip?
Were the people at MS who made the chip really incompetent - or did MS just hire them from another ASIC company? There is no guarantee this wouldn't have happened if they did go to a ASIC.

That's true, but, if the did go to an ASIC vendor they could have got a contract indemnifying them from taking losses when the chip turned out to be flawed. By doing the chip design themselves, they saved a little bit of costs, but also took on all the risks of having a bad design.
That's what the parent poster is alluding to. A manager with experience in technology would have understood that, while designing your own chip might have been cheaper, it would have also introduced significant downside risk, which ought to have been factored into the equation. Farming the chip design out to a third party, while more expensive in the short term, would have entailed less long-term risk.

And for balance the problem I have with engineers as managers is that it's possible to learn the people skills stuff but you have to understand why it's important and want to do learn it. It's all too easy to stay in the comfort zone where you basically sit in a dark corner somewhere and write code if that's what you enjoy rather than forcing yourself to talk to people.

Personally, based on my experience in teaching VHDL/Verilog to students, I believe that it is much more likely that a software engineer would choose to use a much more asynchronouos approach, and get it totally wrong
Most hardware designers would tend to avoid async logic as much as possible to reduce the verification time. Sometimes you have to do it when doing clock domain crossings, etc, but it is usually not something you are looking forward to.

It is true. You should not unnecessarily muck with VHDL/Verilog and 3rd party cores even if you work with an FPGA. This will not kill you, but it will make you poorer. HDLs are notoriously kludgy, and it takes a lot of effort to do it right. Proprietary cores rarely work as documented, and you have no visibility into them. When multiple cores are used, it's one large fingerpointing game between vendors. And you need to have good, experienced HDL coders. And you need to have all the tools, they cost big bucks.
But that's with mere FPGAs, where you can update your design whenever you wish. However here they are talking about ASICs - where all the wiring is done with masks when the IC is made. You'd have to be certifiably mad to even think about a casual design like this. ASIC designs are done by very competent teams, using "10% coding / 90% verification" time allocation, because you can't afford /any/ mistakes. And even then you make mistakes; but experienced teams with good tools make those mistakes smaller, and they call them "errata" - something that is not right but can be worked around. When you make the F0 0F bug, though, you trash the whole run.
So Microsoft risked a lot when it went for an in-house design. I am not surprised that they failed. They should have counted all the successful 3D video companies on the market and asked themselves why there are so few, and why top gaming cards cost so much.
But if you're a cash rich company then the bias will be to try to do as much as possible in house, because that gives you more freedom to value engineer later.
I am not MS, but I don't really see much business value in rolling your own video controller. More likely the NIH syndrome kicked in, or some people were overly concerned about their job security.

Without an ASIC vendor? As in, taped out GDS2 directly to a fab like TSMC? What process node? If you say 90nm or lower (which is the kind of ASIC we're talking about here) I'd have to call bullshit and ask for the names of these companies.
