An automated manufacturing system and method is provided. The system includes a software system and a production system. The software system includes a design module, an engineering module, and a manufacturing module for the design, engineering, and subsequent production of a prefabricated building product. The production system includes a matrix of cells and a plurality of robotic production units configurable with a plurality of production tools. The matrix includes a number of columns and a number of rows, each column representing a product to be worked on and each row representing a type of work to be performed on each product. The system processes a building model and configures each cell to perform specific work with one or more robotic production units and one or more production tools. A prefabricated building product is built in stages as it moves from cell to cell.
