Because you never know if your problem is the real problem or if there are other problems behind these problems. When I first joined the company, the supervisor gave me a long list, hoping that I could chat with them and get to know these people. There are stakeholders with various functions and different departments but related to our products, so I knocked on them one by one. Strangers, chatting one by one, this thing was very unaccustomed to me at the beginning, and I was a little worried that I would be abrupt when I even sent a message.
It was only later that I found out that "knocking on strangers" and "knocked by strangers" are the daily routines of large organizations! In such an photo color correction services environment, in addition to learning knowledge by yourself, in order to make the project successful quickly and efficiently, it is more important to find people who have the knowledge or decision-making power to cooperate to solve the problem. And because it is impossible to understand the whole picture of the product, how to maintain a cooperative relationship with the stakeholders to achieve the goal is very important.
Building relationships is really important, and the more common practices I've observed are often looking for people to chat with over coffee, having regular weekly or bi-weekly catchups, and so on. However, due to the need for "navigation" in large companies, senior employees will be very popular. Both my current supervisor and former supervisor have been in the company for 5-8 years. Every time there is a problem, they always have a way to find a way. Some names gave me the ability and knowledge to ask, and this ability and knowledge is critical for product managers in large organizations.
