Cabe, yes you cant always satisfy every customer but according to marketor customer is always right never say no to the customer like its an old saying that boss is always right . But i guess these days this trend is moving and changing marketors and customer service industry is now focussing more on explaining the things to the customer and are working on how politely and calmly we can explain the customer that they are wrong without offending them and hurting there feelings .
Great article Jay, and brought not just a little nostalgia back to me with mention of the 8051 - the microcontroller I used in my student days and the pin to pin compatible DS5000 that I had a great time with...rather than burning an EEPROM, it had NV Ram that could be loaded via a serial interface - a big deal back then.
I wholeheartedly agree with you on lessons learned but some of that comes through hard earned experience. In my test engineering days I learned the hard way not to set a projected project completion date until I checked the lead times of any specialized equipment that was needed for the test set. Checking part availability and having redundant sources are other lessons learned. If there is a change in personnel involved with the project, making sure that everyone is brought up to speed so that decisions based on erroneous data due not occur. Sometimes the customer you have to say no to is internal - which can have some unpleasantness to it, but is necessary and best in the long run, even if they don't want to see it.
Thanks for sharing your experience, Jay - I always believe we can learn not only from our past mistakes, but others as well.
Jay, excellent post. I own an engineering consulting firm and have faced the very same demands from customers. You are considered to be "hard to deal with" if you refuse and nervous as a cat if you comply. In my case, the demands came from upper management to the project engineer, i.e. my client, and then to me. Management wanted advance information so they could put together a sales pitch for an upcoming tool and equipment show. I was caught in the middle BUT the big issue came when the delivery date slipped. At their show, comments were made as to when the product would be available for sale. We missed the date by 12 days but it could have been 12 years. Management was incensed. I lost the customer and lived hard for several months after that.
My sympathy in dealing with such a customer. I have had instances where designs needed to be sent for quotes before the exact dimensions were known, and every single page had to be marked "for quotetion purposes ONLY, positions will change, tolerances will not change". That was enough for most machine shopsto deliver a valid quote, and only one ever made a part to the wrong drawing.
And as for part prices changing and parts not being available, I inherited an instrument amplifier board design that used a very nice single sourced part whyich wound up not being available because the US military had priority and got all of them that were produced. So a total redesign had to be done, but this time I had a firm agreement with Analod Devices that the 2B31 would be available for an adequate time and in adequate quantities. That part is obsolete now, but at the time AD certainly saved me from a disaster. The engineer who designed the original board had left the company and I had to recover a few of his goofs. But the good recoveries did help my reputation there.
As a wise marketing person once told me, "the customer isn't always right, but the customer is always the customer".
If you have to deliver something, but know it shouldn't be used, do something like adding a comment to the layout that puts a "PRE-RELEASE TEST DESIGN, NOT FOR PRODUCTION USE" label prominently on the board. If they really don't want to use it for production, they won't mind.
I once saw a document distributed against the author's wishes; he added a watermark on every page that said "This document is incorrect. Destroy before reading." It got the point across.
Jay, you certianly were in a bad place in this situation. It is sometimes hard to satisfy all of your customer's desires. It looks like you were doing the right thing, but got caught trying to please the customer as well. When I was at IBM I always wondered why there was so much emphasis placed on the announcement letters. This is the reason.
Wal-Mart will hold its second Made in the USA Open Call July 7-8, at its headquarters in Bentonville, Ark. The event will be a repeat effort by the world’s biggest seller of consumer goods to increase the amount of US-made products it sells in Wal-Mart stores, in Sam’s Club members-only wholesale outlets, and on walmart.com.
From design feasibility, to development, to production, having the right information to make good decisions can ultimately keep a product from failing validation. The key is highly focused information that doesn’t come from conventional, statistics-based tests but from accelerated stress testing.
There’s a good chance that a few of the things mentioned here won't fully come to fruition in 2015 but rather much later down the line. However, as Malcolm X once said, "The future belongs to those who prepare for it today."
