+Batching is more convenient
++ As the raw materials are not the same, you must plan . Making big batches + makes the production easier: you add stock so you. +
++ But here comes the bullwhip effect: if you plan with margin, your + suppliers do it too, with margin. These margins add up and even a slight + change in priority demands a high change in the supply network. +
++ The more stock there is, the more latent payments there are and the more + paymeents are still waiting, the more you need to be good at planning + batches. +
++ So producing a bit of everything with small batches is the way to + go and that's the core of Heijunka. +
++ But heijunka needs conditions. First: + SMED +
++ We didn't talk here about how we manage products that need different time + to be produced. There are multiple difficulties when we try to level the + production: by doing everything every day you must have much more + flexibility in + what you can make per day. +
