Fishbones by Number and Title

Fishbones are organized and grouped by a particular topic (e.g., Yeast Viability and Vitality). Under each topic follows a numbered series of fishbone diagrams pertinent to each subject. In some cases, there may be only a single fishbone, while for others, such as Yeast Viability and Vitality, there can be multiple series of fishbones (what a surprise, eh?!). In these cases, different fishbones within the same series have alphabetical letters assigned to the series number as new fishbones are added (e.g., Ia, Ib, Ic, etc.). The fishbone title is linked to the diagram itself. Following this structure, the complete set is organized as follows:

A. Yeast Management Processes Impacting Yeast Viability & Vitality

Id. Yeast Storage
