That point about starving their supplies is not so dumb as you think. I know something about vehicles manufactoring, and I know that most of this factories works with minimal stock, to save money. Just in time , all other kinds of6Sigma and lean strategies are employed in this to minimalize the stock supplies, just for the fact that in the material is money. If this fabric has some problems, they would maybe posses one or two days material reserves, they are at best very dependant on the clever logistics. If we keep disrupting the supply lines for just one parts, that has to be assembled to the engine at the beginning of the manufacturing process, we should make the assembly lines stop. And if we disrupt the logistics for the part that is assembled at the end of the line, they should take the risk and manufacture uncomplete products...which costs even more, because once the parts arrive, they will have to get to goods in proces back on the line and that, believe me, would cause absolute logistic chaos. And if we intercept this chaoss with some false data, casing quallity or logistic problems, they will not just have to stop current production but they would have to work over time...with their financial activa deptlet on the part held in the storage bay...beautifull. And with people angry, overworked it takes only a little to cause some serious hot moments for the management explaining the situation to board of stock owners.
