I wonder what their manufacturing processes are like, such that they could accommodate this kind of flexibility.
Re:Whatever happened to Japanese laptops? by yaakov34 on Monday November 07, 2016 @05:10AM (#12889980)
In most manufacturing, you have a prototype hall or floor where you have somewhat more general purpose/flexible machines with a lot of manual intervention to make small quantities of prototypes, and factories with automated machines set up to make the exact parts you need for your full production.

This was always my experience in electronics - you, as the development engineer, set up small-scale production (going from prototypes to EV or engineering validation articles, which are basically the final product produced by these manual/slow methods), and then manufacturing engineers work with you to transfer your processes to an automated assembly line making who knows how many units a minute.

It's not unusual to produce a special prototype in the small/experimental floor; I mean, Apple probably goes through hundreds (or whatever) of prototypes and test articles before releasing their next phone, and they are certainly not stopping their million-per-day manufacturing plants to make them. However, it does show impressive commitment to the customer on the part of Fujitsu.

Also, electronics is more cyclical than cars (3-year-old model may be completely different and useless compared to the current one), so it is common to produce everything in batches rather than "the Toyota way" with just-in-time. In other words, if a laptop model is sold for 2 years, the whole run may have been made in 6 months, and then you have that manufacturing equipment sitting idle while the next prototype is worked on, so you may have equipment and engineers to spare. Only a few of the highest-volume factories (e.g. Apple again, I assume) run at full capacity all the time.

You seem to want answers at a level that only the engineers at Fujitsu (not Toshiba, according to the OP) can provide. I can comment on some of the specific questions, but obviously I don't know what went on at Fujistsu.

1) The final development PCBs (the engineering validation articles) are actually identical to the production PCBs. Your final EV revision becomes revision 0 in production; only the manufacturing method changes. So the prototype floor definitely has the ability to make production-quality PCBs.

2) The design change may or may not be complicated. Adding a port typically refers to a port already supported by the chipset; so you add a ribbon connector for it and change the layout only.

3) You generally wouldn't have full pick-and-place automation for making prototypes. There are manual tools (sort of semi-automated) for making a few PCBs. A large company is making prototype PCBs all the time. They know how to do it, and they don't stop manufacturing for it.

4) For the case, the easiest would be to rework an existing case (add a slot). Creating custom injection molds is kind of a big deal. Then again, if Fujitsu does that in house, maybe not that big. Don't know.

5) The expense would not involve a cash outlay, but it would definitely involve diverting engineering, manufacturing and sales resources to even communicate and deliver this whole thing, let alone make it. The engineers may have been pulled off something, or may have been waiting for work; business hasn't been that great for most manufacturers, if you haven't noticed. No, I don't know how Fujitsu accounts for this or why they made the decision to go ahead. I am not a manager at Fujitsu. I can tell you that most companies are very loathe to let prototypes and one-offs to leave their hands at all. So it's definitely impressive on Fujitsu's part that they would go to that length.

Degrees are expensive, and if you don't get to bludgeon people with them, what's the point?
Re:Whatever happened to Japanese laptops? by oblio on Monday November 07, 2016 @11:18AM (#12892190)
This is the bad place to try to bludgeon people with your degrees. It kind of reminds me of two funny moments:

1. A group of British construction workers in a Discovery Channel documentary loved to start fights in random bars until one day they accidentally started a fight in a bar frequented by members of a local boxing club.

Some of the external ports in my lifebook are simply mounted on the housing and connected to the boards by cable assemblies, so:

They may have stuck the needed connector on a wire and used an NC mill to make an appropriate cutout from an existing housing part.

It is literally less than 1 hour to design and tape-out a inch-square pc board to accomodate a connector and cable termination. I am a little guy and have to wait a week and pay five bucks to have this manufactured. Fujitsu probably had this done the morning after a solution to the request was devised and approved.

I think you are right, but the idea that they were willing and able to actually execute was incredible to me. Alot of competence and strong relationships were in place in the sales and manufacturing organization for that to happen.

As a customer, I think we bought ~1,000 units in the end. I've rarely seen that type of capability in my career, and it's too bad that the realities of the market have likely nixed it.

Principle 3

    Use "pull" systems to avoid overproduction.
A method where a process signals its predecessor that more material is needed. The pull system produces only the required material after the subsequent operation signals a need for it. This process is necessary to reduce overproduction.

I too have heard of Kanban and JIT from my fellow arrogant valley douches. I would like to understand the specific manufacturing processes that make one-off products of production quality viable.
Re:Whatever happened to Japanese laptops? by lisivka on Monday November 07, 2016 @04:19PM (#12895232)
I suggest to read Gemba Kaizen books. Yes, it is hard to understand first, but then you realize that Toyota Way is like 3D printer — add only what is needed right now, do it fast, be precise.

So yes, you are right — Toyota Way is not viable for mass production, but it perfect for areas where human labor is still plays major role in manufacturing, e.g. programming.

It was probably more like having some engineers and guys in shop/factory work weekend to meet the demand, on top of what they were already supposed to do.
Re:Whatever happened to Japanese laptops? by notoothpaste on Monday November 07, 2016 @04:49AM (#12889899)
In order to create a prototype with a port in a different location, they would need, at the very least, to produce a one-off motherboard PCB, and a one-off injection molded case. That they could justify doing so to produce near production quality results for a small order either indicates impressive manufacturing flexibility, or an inefficient manufacturing process.
Re:Whatever happened to Japanese laptops? by kw71 on Monday November 07, 2016 @06:15AM (#12890226)
Your assumptions that they would need to redesign and tool up for brand new complex motherboard and housing parts are incorrect. This is a foolish way to accommodate a request to physically move a connector.
Re:Whatever happened to Japanese laptops? by lisivka on Monday November 07, 2016 @04:55AM (#12889927)
Their process is implemented for flexibility first, then for mass production. Look at Toyota fabric [1]. Do you see lot of advanced robots to reprogram for each new model?

Re:Whatever happened to Japanese laptops? by notoothpaste on Monday November 07, 2016 @05:11AM (#12889986)
So how is/was Fujitsu's laptop manufacturing tailored toward flexibility? I want the details. If all you can do is passive aggressively repeat vague ideas that were printed in mainstream management and manufacturing texts decades ago, don't respond at all. Nobody cares about or wants your input.
Re:Whatever happened to Japanese laptops? by yaakov34 on Monday November 07, 2016 @05:42AM (#12890110)
And you think that someone from Fujitsu (where it's 8 in the evening, BTW) is going to jump in here and explain their factory layout to you, because you've put your foot down? The best general answer you are going to get is "They made it using whatever process they used to make prototypes. Probably". You want names, ranks, and serial numbers - try writing to Fujitsu. Preferably while being more polite.

Re:Whatever happened to Japanese laptops? by yaakov34 on Monday November 07, 2016 @06:50AM (#12890372)
Guess what - you can't tell us what to do, any more than you can order Fujitsu's management to appear before you and testify. Not being the dictator of the universe is very unpleasant, but most of us have learned to live with that by the age of 3. And if you think I've been commenting here specifically for your edification, that's wrong too.

As for being downvoted and needing a new account - I personally never care enough any more to get involved with that, but yeah, that's a good guess by the time after the West Coast wakes up, so have fun with that.

Yeah, the Man has been busy keeping you down, hasn't he?

I appreciate your offer of friendship, but since this morning, after a conversation with the neighborhood not-quite-right-in-the-head lady, it would appear that I am getting all the crazy douchebag cultural immersion that I could possibly want. But thanks anyway.

Re:Whatever happened to Japanese laptops? by thedaniel on Monday November 07, 2016 @04:58AM (#12889939)
Or... that it was an option for port placement they'd already considered, and they pulled an existing prototype out of the library, which seems more likely to me.
