Continuing along with my occasional discussion of Lean Six Sigma topics which apply well to farming, here is the next: the Pugh Matrix (or decision matrix method). We are often faced with making a decision between multiple choices which have complex variables. In engineering and manufacturing firms, obvious examples are deciding between two major design path choices, or selecting a vendor who will supply components long-term or perform some sub-contracted duty.
These are decisions where there are many pros and cons between all the choices, and it can be overwhelming trying to choose which is the best solution. The worry is that if we just default to our “common sense,” we may end up being biased and unable to make a truly objective choice. We may unconsciously place more importance on a certain consideration than other critical factors; and in the end, not select the best solution. With vendor selection, it can be easy to be swayed by one you know well and like; or by a good salesman. With design choices, the most assertive person in the room can sometimes sway the group in one direction. With farming, especially animal selection, the potential for bias towards our favorite animal, or best-looking animal, is huge.
