(This past illustration describes something that I performed in my career, either for a Bredemarket client, for an employer, or as a volunteer. The entity for which I performed the work, or proposed to perform the work, is not listed for confidentiality reasons.)
A company wanted to enter a lower price tier with a product designed specifically for that price tier.
For an early version of a product for this market, I created product requirements and demonstrated the product to prospective clients.
For a later version of a product for this market, I was in a different role, but I assisted by using county population as a proxy value to identify target customers for the new product. As the target requirements were modified, I adjusted the list of targeted counties accordingly.
The early product sold in limited quantities and was subsequently discontinued. (This pricing tier is in a challenging market.)
I do not know the status of the later product.
