You can always assign homework to go back and validate the figures later. Regarding the data boxes, if you don’t have all the data perfectly collected on the day of the mapping exercise just do the best you can. This includes the process boxes and data boxes. Step 7: Focus on the material flow firstįocus on the material flow side of things first (bottom portion of the map). Experiment and do what works best for your situation. Yet another trick is to have the team divide and conquer as you send some off to map the beginning section, some to the middle, and some to the end. I recommend you nominate a scribe and have them draw the map for the team.Īnother trick is to ask each person on the team to map it out so you can compare and consolidate when you get back to the room. Next, we start at the END of the process and begin drawing the map back to front. We also note their monthly and/or daily demand along with the takt time as calculated in step 1. On the top right-hand side of the paper, we draw the little saw-topped box representing our customer. Step 5: Draw in the customer box / details. Remember, we eat an elephant one bite at a time. It’s important to also define the start and stop point of the process. Quickly walk the process with your team in order to understand the general flow. Then, when you are ready to share your masterpiece with senior management you may choose to go for the software. It’s big, but not too big to carry around.įinally, while I will be drawing the value stream map using software in this article, I recommend you always draw the map on paper first. Personally, I prefer the 11”x17” paper size. Your standard 8.5”x11” piece of paper won’t cut it. Please, I beg you don’t use a pen when drawing these. The best value stream maps have eraser marks all over them. In other words, we need to produce a completed PB&J sandwich every 39 seconds in order to satisfy customer demand. But in case you don’t, I’ll tell you the takt time is 39 seconds per piece. I recommend you practice punching this out. In our example, we have a daily demand of 700 pieces with the following arrangement. If you don’t remember how to calculate takt time this free resource should help you along. For those interested, that’s the first letter of each of my three kids’ names! Step 1: Calculate takt timeĭon’t proceed until this step is done. Our PB&J manufacturing company goes by the name of KB&R Inc. To help you visualize things I have created a fictitious example of a peanut butter and jelly sandwich factory. OK, let’s learn how to create a current state value stream map. And for the rest, you can use a cheat sheet like I do! It’s time to create the map! There are really only a handful of icons you will always use. So, the only way you will not be a bit intimidated (assuming you have never seen a VSM before that is) is to study a bit and practice, practice, practice. Luckily, I had some great instructors and I did quite a bit of self-study to get past my initial fears. In short, I was a bit intimidated by the whole experience. It was a bit messy, and I didn’t know what any of the little shapes and icons meant. I wondered how anyone could benefit from it. I remember the first time I saw a value stream map. Will the process change a bit tomorrow? Sure. Instead, we are interested in how the process is performing today. We are not interested in how the process is supposed to work or was designed to work. The key to creating an excellent current state VSM is to document what you actually see with your own eyes. The challenge lies in seeing it.” -Learning to See, Lean Enterprise Institute “Whenever there is a product for a customer, there is a value stream.
