We all know that we need to consult specialists for different situations in our lives. For example, if we want to learn a foreign language, we go to a teacher, if we have a medical problem, we go to a doctor. And if we are, for example, a travel agency and we need a special software to show us instant up-to-date information about the hotels in our portfolio, it might be easier to go to an IT outsourcing company than to hire a dedicated person for this project.
