The best way to ensure that members of a group share the mission, vision and values of the group is to recruit people that already embrace those values. That means that part of the recruitment process for students, faculty and staff should be articulating these values and assessing how well the individual holds those values Orientation. One of the goals of orienting an individual to a group is to reinforce the values of the group through shared experiences so the value to be reinforced moves from their head to their heart. In my experience this is best done through facilitated experiential learning activities. Good orientation programs will get an individual excited and engaged, but they don't get the individual integrated into the group.
Integration requires a sustained effort over a period of weeks or months.
It requires the establishment of an ongoing process and periodic reinforcement mechanism to sustain the excitement and engagement of the individual. Ongoing maintenance of the culture is primarily accomplished through three mechanisms. For example, if service is a value the college wants to promote, then the college needs to promote and sponsor as many service oriented programs as possible, either directly or through existing community service organization. Third, celebration of people that live the values through recognition and awards. Community is built through shared experiences and interests.
