Synergistic Red Fuse ...

I have a Beeswax fuse in the pre that replaced Audio tuning Supreme with fantastic results. Only trouble it needs a very long burn in.

I've worked as a 100% commissioned salesperson for most of the past 53 years. In my field, its important to understand personality types. There's four basic types with combinations mixing the four.

Engineers are a breed of their own. Its almost impossible to get them to make a decision on the spot. Many of them suffer from "analysis paralysis."

The best approach with an engineer is to leave him/her with all of the paperwork/contract and let them think it over, over night, then call them the next day for their decision. Many times they will say ... "Oh, everything looks great. Its all signed. Come on over and pick the paperwork up."

Salespeople who try to pressure an engineer into a decision before he/she is ready to make the decision are dead meat.

Each of the four personality types has its biggest fear. With the engineer, its the fear of criticism. That's why they measure 15 times and cut once. That's also why they take a doubting posture when it comes to things they can't measure. 

Of course there are varying degrees and a mix of personality types, but normally one type will be dominant in each person. If a salesperson is to be successful, then its important that he/she understands the differences and learns to "sell" to each individual type. 

The engineer, because he/she carefully analyses everything to death, usually ends up with a nice, comfortable retirement because they have planned for it. They are financially frugal and very intelligent people. Also, they drive their spouses crazy. :-)

With the engineer, its the fear of criticism.

Not sure about that. The best engineers strive for accuracy and avoid making mistakes that will have consequences to someone down the road.

Almarg is a good example here.
Also having a law background puts him in a class of his own.

Read up about the Challenger space shuttle disaster for a textbook example. I worked in Huntsville Al. at the time down teh road from Marshal Space Flight Center where those engines were tested. My companies Computer Aided Design software at the time was used to design the shuttle. Human error not technology led to its fate. I was still a young pup but I witnessed how all the engineers I knew were totally shattered that day.

As a general rule, each personality type has its main fear. Fear of criticism for the engineer type. Fear of being taken advantage of for the law enforcement type. Loss of social approval for the back-slapping salesman type. I forget the last one. But, these fears are with us all. Its interesting stuff and very important for folks who work with the public to know. ... especially people in sales. 

I used to be intimidated by the engineer type in a sales situation because they would ask so many minutia questions. I thought they were questioning my integrity. With me, it was that loss of social approval thing.

Once I learned that engineers CANNOT make a decision right after the sales presentation, and that they MUST "think it over," my closing ratio with engineers went up exponentially.

In most cases, the engineer type is going to interview at least several salespeople to get all the facts he/she can. These salespeople, not understanding the psyche of the engineer type, would pull out their hammers and try to beat the poor guy into submission in an effort to close the sale.

 Ha ... I'd just leave the paperwork overnight, let him/her dissect it to their heart's desire, then call them the next day to see if I could pick up the signed paperwork and start working for them.

I've been told many times by these folks that the reason they decided to work with me was that I was "so low pressure."

OP

When in product development, I worked with many technical marketing folks and always got along well with them, especially the ones who also valued integrity and accuracy. The best companies always place top value on that.

Also I will add that the creme of the crop when it comes to engineers have extreme confidence in their knowledge and abilities and fear little in that regard. Also pretty much true with the best in most any profession I suspect.
