The concept of product management originates from a 1931 memo by Procter & Gamble President Neil H. McElroy.
As a result, product managers are critical in driving a company's growth, margins, and revenue.
Depending on the company's size, industry, and history, product management has a variety of functions and roles.
Frequently there is an income statement (or profit and loss) responsibility as a key metric for evaluating product manager performance.
Product managers analyze information including customer research, competitive intelligence, industry analysis, trends, economic signals, and competitive activity,[1] as well as documenting requirements, setting product strategy, and creating the roadmap.
