Christian, It seems to me that you are confusing yourself with your own reasoning....
Look at it from this simple and absolute perspective: when executing a production run that results in the end product beer the outcome of that intention is either beer (success) or no beer (failure). The rest is a by-product. Defective end products don't exist. Just end products (success), wanted by-products (e.g. waste - as in the bags the barley came in - or in the beer scenario yeast-residue) and unwanted by-products (the stuff that you get when failed) It also seem to me that you are the only one in your organisation carrying the burden of implementing business case/solution/process and technical adjustments. Beware of falling on the knife of your own promises.
