Imagine you are building a Lego castle. You need to follow a set of instructions to put all the pieces together in the right order. An open shop works in a similar way.
Instead of Legos, there are machines and tools that help workers make things like furniture or cars. In an open shop, everyone works together to create the final product, but they don't have a set way of doing things like the instructions for the Lego castle.
Each worker has their own skills and ideas for how to make the product, and they work together to figure out the best way to get it done. Think of it like a big group project where everyone brings their own strengths and ideas to the table.
The final product is still made with the same quality and care, but the process of making it is more flexible and collaborative.
