When a business is choosing which company to outsource with, location can often be overlooked in favour of the most appropriate specialist for the project. However, location – and especially proximity - should be a critical part of the decision process. For example, if your company is based in Europe, it will be more difficult to outsource from a provider based in Asia, due to a mixture of time, travel, language, and perhaps cultural differences.
Over the last two decades I have had the opportunity to work with some of the largest (as well as mid-sized) enterprises who had outsourced their IT work to offshore based teams. The offshore teams themselves were either part of service providers who were domestic companies out of North America/Europe, or part of providers who were headquartered out of India (with largely a sales presence in North America/Europe).
