The following is adapted from Build What Matters. One of the most fundamental experiences in an e-commerce product is called “finding,” showing buyers the items they’re looking for. At eBay, I was product manager on the finding team responsible for the item details page, which showed what sellers listed. Counterparts on my team included product managers for searching, browsing, the bidding flow, and so on. Our team collaborated well, worked hard, and learned a great deal from one another. We also made our share of mistakes.
