|10. THINK IN TERMS OF LONG-TERM MANAGEMENT|
What you are aiming at will not happen in one day, it is a long-term endeavor.
You need a dean or a manager in charge of all immersion activities, and a steering committee who can consult broadly the various people involved in the project.
You need regular feedback and surveys, otherwise things may quickly get sour or dysfunctional. Dealing with another language and culture involves cross-cultural pragmatics, intercultural sensitivity, and constant problem solving.
