A Spaghetti Chart is a map of the path taken by specific products as it travels down the value stream in a mass-production organisation, so-called because the products route typically looks like a plate of spaghetti.
Is a graphical aid used in lean manufacturing activities. It is used to detail the actual physical flow and distances involved in a work place. Processed that have not been streamlined frequently are poorly laid out with work/product taking a path through the work area that looks like a mass of spaghetti. To create a spaghetti chart you first create a scale man of a work station or work process. The next stage is to draw a line from the initial point of the work to the next step, and so until the work/product exists the work area. Examination of this resulting chart will show where improvements are to be made. Using the information provided by the process chart is used to physically relocate work steps so that work/production does not backtrack at any point and proceeds in a linear fashion. A common end layout resulting from using a spaghetti chart is a “U” shaped workstation where materials enter one end and exits in Parallel fashion with all work steps completed.
