Pros
You learn allot of software to do the jobs.
Cons
Typical big company takes a year to do little or nothing. One group doesn’t know what the other is doing. Drawing checkers with 20 yrs. don't understand CAD. A drawing has to have a suppressed ( flat pattern) feature for sheet metal or it will not show as a bent part. Designers are taking thing off drawing blocks while checkers put them on. IT can take 2 wks to setup a simple meeting once you find all the required people. List with the product managers are constantly changing. To get this done fast you spend allot of time commutating between groups, setting up Power Point slides, filling out 4 sheet workbooks. Contractors are restricted from information that is needed to do the work as well as training material. They have been up and down in production, twice in the last four years. Contractors will probably never get hired so they don't pay benefits. Anger management is needed throughout the company, I watched a dozen people blowup at someone else.
