As business becomes more and more global through the World Wide Web software developers increasingly need to make applications multi-lingual and culturally aware. Only 8% to 10% of the world's population speaks English as their primary language. Even in the United States, there are Spanish and Japanese TV stations that address the needs of the high percentage of non-English-speaking ethnic groups. People in other countries are different and need special attention in a user interface design project. Not designing with language and cultural differences in mind is no longer an option that companies can afford.
International usability is not a minor issue ; it has a major impact on your success. To sell in foreign markets you need to speak in the language of your customer because in most countries , computer users prefer to work with software in their native language. Localization has been proven to be the key factor for international product acceptance and success.
This means , you can increase the size of your market and therefore increase your revenues by reaching a wider market and have possibilities to enter markets that would otherwise have been unavailable to you.
Moreover , local law often requires all imported hardware or devices to be accompanied by documents in the local language. In addition, by localizing your product you build credibility as a global player and remember
the competition is tough. If you do not take an action now, your competitors might win the game.
