This publication is intended to help production staff understand (1) what job specifications are, (2) why written specifications are important, and (3) what is involved with documenting specifications. A definition of job specifications is followed by a discussion of the importance of and necessity for such specifications as regards the rehabilitation facility. The section on determination of job specifications is divided into two parts. The first part discusses the requirements of materials for the job and their relationship with shipping/receiving, manufacturing control, and quality control. The second part of this section discusses manufacturing specifications from the standpoint of the support services restrictions placed upon the manufacturing of the product, namely shipping/receiving methods, manufacturing control, and quality control. Forms and checklists are appended. (YLB)
