For effective sales management one can apply Drum Buffer Rope to the sales process similar to the way it is applied to operations.
Yes, i agree with Arash by matching supply with demand , and while you agree with me that demand is a result of marketing work then supply must follow it since per unit inventory cost and inventory turns depend clearly on demand, and we know inventory is a capacity constraint.

In manufacturing industry the capacity production is at1st place.
A capacity based marketing then refer to value base marketing & order base marketing.
A company should adopt experience sale and marketing persons to get regular job orders as per the market requirement and then the production unit insure the quality and value of the product.
I understand the value base marketing and capacity base marketing as a foundation of manufacturing industry, because high production decrease per unit cost and and high sale volume increase the revenue.

Yes Sir, in new world you must produce your products based on orders , it's not profitable when you produce your products and store them , if you have a professional marketing team , you can manage your factory to produce the goods that you have order for them , not for store ,
