Proof in point. Mr. Know it all here, knows everything and will never listen to actual information from someone who knows 1st hand of how things are done. He knows NOTHING about the design and development process, yet he tries to debunk everything that I just said. Do you see me saying things, that I know nothing about?? No....I'll admit, I don't know a lot about the different variations of 4 wheel drive. I won't act like an expert when I know for a fact that I am not.....but just look at that reply above from someone who has never done anything in the development stages of a vehicle.
Yes....Toyota's quality has gone down recently and I can explain that to you also with another long story since I know what has caused that problem recently and I'll tell you WHY it will improve while Chrysler's won't and will most likely drop in quality.
Toyota develops it's vehicles built on the premise of a Japanese term called
"Kaizen". The English translation of Kaizen means
"Continuous Improvement". So what they do is with each new vehicle they design is that they use their previous design and then improve upon it in the next version and then add new technology as the market which you as a customer may be looking for. So as a supplier to Toyota and working with them directly, we reuse core parts of our previous design which we know has some long term real use reliability to them in the vehicle. We then add new functions and features to that design. Then we focus in on testing the things that have "changed" within the design. We already know we have reliability in the vehicle from the previous design in a majority of the core design sections, so we can now focus testing on the "changes" in the design and thus become more efficient, focused and in dept in our reliability testing processes. So once you're supplying parts for Toyota, you will usually remain a supplier for them with the next design and for many years to come where they will continue to work with you and focus in on improving your previous designs, so old problems will never remain the same new problem.
This Kaizen design approach has one drawback to it though. It sometimes means that you start to fall behind on the technology curve, because you're being forced to reuse parts of your old design and not being able to add the latest and greatest gizmo feature because the old design can not support it. So while Toyota's quality was continuously improving, they started to fall behind on the latest gadgets and gizmos that you as a customer wanted in your new vehicles. So a few years ago, Toyota had to become more aggressive in this area and started to make bigger changes in their designs. More changes increases the probability of things that can go wrong with the Quality of your parts, but it was something Toyota had to do, to remain competitive and to be able to offer you as a customer what you wanted.
MORE CHANGES=HIGHER PROBABILITY FOR QUALITY PROBLEMS. I bolded that statement, because I will refer back to that later.
So anyways Toyota's quality took a dip as a result of that. Now that they've caught back up on that technology curve, they are back to focusing in on minimizing the changes to bring that quality back up to what people have grown accustomed to from previous Toyota vehicles. Kaizen is a way of life throughout Toyota. In their design processes, in their production processes, and in their testing processes...these things are ALL therefore "continuously improving" throughout Toyota.
Now since TJ mentioned FORD, I will talk about what Ford does in their design processes when developing a new vehicle and working with their suppliers. Chrysler isn't as bad as Ford in this area, but they also do this. When it comes to designing a new vehicle, Ford will invite all their potential suppliers into a bidding war for the business of supplying a part. They do this electronically on a web based bidding internal software utility. It's basically a lot like eBay, where they are auctioning business to suppliers. Their goal is to drive down the cost of the parts that are being supplied to them. Say you have 10 potential suppliers who want the business. Every supplier can see the current price that their competitive suppliers are offering FORD to get the business. So the other suppliers will then offer their part at a lower price to try to get that particular business from Ford. I'm not making this up....it's basically bidding for business through an Ebay method of auctioning. Usually the lower price supplier has a good chance of getting the business with Ford. Often suppliers who are desperate for the business or just want to get their foot in the door will put bids in that are below the costs that it actually costs them to make the part. The reason why they do this, is that often prices of components and pieces will drop over time or there becomes another cheaper part that they can use instead, and what they do is they make engineering
"changes" after they get the business that will lower the cost of making their supplied part, where they can eventually see a profit.
2 major "quality" problems occur in this process.
The 1st being, is if the previous supplier of that part doesn't get the business due to not being able to lower their price enough, the new supplier's part is a totally NEW design. It might not have the same problems that the previous supplier's part had, but they really don't know what new problems may await them down the road, since they have no history with that new part's design to be able to rely upon. The previous supplied part supplier also loses the opportunity, to improve upon their previous problems....thus ensuring they don't happen again, and therefore there is no "continuous improvement"......no "Kaizen". You are basically throwing the baby out with the bath water and starting over with a new design and new potential problems.
The 2nd problem is now the new supplier since, they are now selling a part to Ford which is at a price below what they are able to build it, they WILL be making further design changes to lower the cost, so they can eventually get out of the red and into the green.......which means more "changes". Remember what I said earlier???
MORE CHANGES=HIGHER PROBABILITY FOR QUALITY PROBLEMS. But HEY!!! Ford was able to offer you a cheaper priced vehicle with all the latest and greatest gizmos in it. Just don't act surprised now when your new Ford vehicle starts to fall apart down the road, because now I've explained to you why that will probably happen.
I also have 1st hand experience with Chrysler/Jeep on the same type of thing. Chrysler wanted our part in their new vehicles with all the latest and greatest gizmos on it and they wanted it NOW!!! We delivered it to them. As a result of it being a totally new design they wanted and them wanting to accelerate the design timing so they could offer it to you as a customer....Yes, it had some initial quality problems when the new vehicles launched. It was a totally new design with all the latest and greatest gizmos on it that Chrysler wanted though. As the problems where found in the vehicles we fixed them, to where we eventually got it to where it was a good quality product. Since there where a lot of initial design problems and the cost of the part was higher than Chrysler wanted to pay......what do you think they decided to due in their future designed vehicles???? They decided to buy a new part from a new supplier who offered them something cheaper and they have no quality history with. So the part we where supplying got to where it needed to be.....and now they're starting all over again with another supplier with a new design.....and new problems.
So Mr. TJ know-it-all. I know you have no knowledge of these things that I just went into with very much depth and explanation with your gear head garage repair experience. Do us all a favor and try not to act like you do. You personally sound like you could use a little "Kaizen" in your life.
