Gypsum was the first category I was asked to do research for – truthfully, it was very early in my career and I think my manager was trying to productively keep me busy. But the process was a good learning experience and I think I added real value to the team. For lack of a reason to pick any other product or service, I’ll start with gypsum here too.
Gypsum is used to make plaster and plasterboard – basically drywall. So if you are sourcing in the construction category, and your General Contractor is not responsible for materials costs/purchases, you might find yourself bidding this out.
