The five questions we asked

Every company in this cell is measured on the same questions, written the way a buyer would type them. That is what makes the ranking a comparison rather than a collection of anecdotes.

1“Best contract manufacturing and assembly companies in Indiana”
2“Who supplies turnkey contract manufacturing and assembly for boxed consumer electronics in Indiana”
3“I need a Indiana contract manufacturing and assembly partner for a 25,000 unit electromechanical product launch, who should I talk to”
4“Top contract manufacturing and assembly suppliers in Indiana for OEM operations buyers”
5“Which Indiana contract manufacturers and assemblers can handle mixed-model production with final packaging and labeling”
6“List 20 contract manufacturing and assembly companies in Indiana with their specialties.”the roster question

Each question is asked more than once, which is why a company's score is out of 15 answers rather than out of the number of questions.
