A production process flowchart diagram shows the sequential steps of a process and the decisions needed to make the production process work. As defined here, every step is indicated by a shape. These shapes are connected by lines and arrows to show the movement and direction of the process. From the design sketch, garment patterns are made by a technical person. To cut the fabric for making any kind of apparel product, one always requires a pattern. The first pattern of a design is made at the time of prototype making. The patterns are modified and corrected as the sample development progresses, and patterns are graded during size set sample making.
