ften in industrial situations the non-productive therblig HOLD occurs and usually can profitably be eliminated by resorting to the use of some device to maintain the workpiece la a fixed position and location. This is especially true in hand operations such as assembly work and operations capable of being made bi-manual, where the versatility of the hand can be used to do more productive work. The purpose of this study is to attempt to develop a checklist which will facilitate a systematic approach to the problem of selecting or designing devices to eliminate the therblig HOLD A surrey of texts on tool design and motion and time study as well as periodicals established basic principles that apply to fixtures which hold a workpiece while an operation is being performed. Using these as a guide a check list has been developed to apply to the therblig HOLD when it occurs. The list is arranged in a sequence so as to facilitate a logical approach to the problem of dealing with the situation and should provoke thought in such a fashion as to lead to the selection of a more suitable device to eliminate HOLD.
