You have selected a production or event. The timing is clear. External arrangements are made. Now, it is necessary to make arrangements with your internal departments that will help you to provide full accessibility. From the lesson, concerning your organization chart, you know that you have to contact and make arrangements with the box office, the front of house manager, the education department or public outreach department, the production manager, and the stage manager.

They have to make up a checklist when selling tickets to the target audience or after tickets have been sold. They have to provide a sign language interpreter on the performance date to support the box office communication with the target audience. Then you make arrangements with the front of house manager. He or she has to know and implement the procedures for assisting wheelchair users. He or she has to know about a customized introductions for the target audiences and related seating allocation. He or she has to provide extra front of house staff for assistance of the target audience in finding their way from entrance to performance room or place. He/she has to organize the hosting and shelter of assistance dogs based upon the received reservations. He or she has to organize a distribution before and the collection afterwards of the accessibility aids, such as AD headphones and hearing loop materials. You also make arrangements with the education departments or the public outreach departments. You have to inform these colleagues about the number and the kind of introductions that are needed, general and customized, so they can create and give the general introduction. They are then able to make arrangements about the time scheduling of the general and customized introductions. They are able to report about this time schedule to the external professionals. You then make arrangements with the production manager. You have to inform the production manager about the fact that a voice recognition and touch tour are being organized as a part of the customized introduction for people who are blind and partially sighted.
