My folks brought me up to remember my manners. I consider I’ve perhaps taken this a little too far when I find myself apologising to people in London who have just shoulder-barged me into the path of an oncoming bus. But manners are important, especially for a product manager, where your success relies on the help of many others.

Contrary to what you may think, most of product management is actually selling. You are continually selling new product concepts, ideas for improvement as well as pitches for projects. What you may not realise is that what most people think is selling isn’t actually selling.

So much of being a product manager depends on successfully persuading and influencing others. Whether you’re presenting your product strategy, presenting a business case to the Board or talking with your customers, you need to know your subject matter: to demonstrate a good knowledge of your products and market to ensure that you come over as authoritative and credible.

One of the roles a product manager or product marketing manager plays is to act as a translator between different groups of people. Sometimes this can be in a literal sense, if your responsibilities span different countries, but more generally this means translating between the market, Sales, Marketing and Development as a minimum.
