You have selected a performance, a production, or an event. The timing is clear. Now, it is necessary to make arrangements with your external professional partners, who will help you to provide full accessibility. From the lesson about your organization chart, you know that you have to contact personal or group companions, who assist outside of the venue the patrons with a disability, the audiodescriber(s), the surtitlers, the suppliers of a hearing loop, the sign language interpreters, the suppliers of vibrating chairs, the supervisors for people who are mentally challenged, and for people with autism spectrum disorder. You dust cover the patrons with a disability, the people who are blind and partially sighted, the people who are deaf and hard of hearing, the people who are mentally challenged, and the people with an autism spectrum disorder. You also keep in mind the accessibility for wheelchairs. You provide all these external professionals with all details of the production or event. You ask all of these professionals to make you an offer or bid for their services, based upon all the provided details. As for the audio describers, surtitlers, and sign language interpreters, you let them know what a rehearsal possibilities are, and what the date of the performance or event is. You agree with them upon delivering preparation and content materials. You also agree about delivery of these materials with the supervisors. To the supervisors mentioned, and a personal or group companions, you communicate about a performance or event date. With those personal and/or group companions, you arrange possible supervision in getting to the venue or performance place and back. You agree with the suppliers of vibrating chairs and the suppliers of the hearing loop about delivery, set up, and deconstruction of the vibrating chairs, and the hearing loop on the day and the date of the production or event. For the audio describers, you think about arranging a possible customized introduction, and you look into the possibilities to organize a touch tour before the production or event. For the surtitlers, you think about arranging support for the scheduled general introduction. For the sign language interpreters, you think about arranging the interpreting of the scheduled general introduction. For the earlier mentioned supervisors, you think about arrangements on making and giving of a customized introduction. Once again, in arranging all of this, you keep in mind wheelchairs. If you have ticked off the list of arrangements, you will be sure to have dealt with all external professionals accompanying the fully accessible production or event.
