Unless your product is used only in the US, you as a product manager should make sure that you are listening to the “global” voice of the customer. Customers in other countries typically have vastly different needs than customers in the US. Localization of your product is something you should account for in the very first release if you know that your product will be sold in non-English speaking countries. Even if your first release product launch plan is limited to the US market, you should make sure that R&D accounts for localization such that when you do decide to sell in the non- English speaking world, you will not have to rearchitect your product. Localization is not cheap, nor is it easy to implement as an afterthought.
You as a product manager should also plan on visiting these customers to understand their requirements before you build the product. Even users in the English speaking world have different needs – assuming that customers in the UK have the same needs as those in the US would be making an assumption to your own detriment. One way to figure out who or how often to visit non-US customers is to look at the percentage of established customer base (or potential market for new products) in the major geographic market segments. Thus, if 45% of your revenue comes from the North American market, 30% from Europe, 10% from South America, 10% from Japan then you should plan on visiting customers (prospects) in these countries using the same ratio. You should then use market segmentation based on verticals to figure out which specific customers to visit.
In my experience, on-site customer visits in countries outside of US/Canada are best arranged through your local rep. This will help you overcome the language barrier and also driving in these countries. This will also help you establish a better rapport and expectations with the aid of the local rep who is more in tune with the local culture.
In certain countries like Japan, it is difficult (if not impossible) to have high level discussions on the customer’s goals and tasks. Often, you meet with folks in the trenches who use your product everyday as opposed to management folks and hence your discussions usually revolve around a laundry list of specific enhancement requests. You should try nevertheless to set expectations and send them a discussion guide long before the meeting so that they know how you would like to structure the meeting. Here is where the local reps can really help overcome the language barrier. After all, whatever you want to send to the customer will need to be translated before it can be send.
Listening to the “global” voice of the customer is not easy and not cheap. But it is something you cannot afford to neglect if your product is sold internationally. With some careful planning, it can be done. If you are going to do this for the first time, make sure you budget enough time, money and resources for couple of “learning trips” before you can fine tune to get the most out of these international visits.
