From cooking breakfast and brewing coffee, you are tasked to document the procedure using Process Flow Diagram (PFD). And using this procedure, PFD, create an efficient kitchen layout. Workplace Scenario: Mother starts the day at 6am to prepare breakfast for the family. Breakfast food consists of 1 viand and rice and brewed coffee. The sequence of preparing breakfast starts with the cooking of the rice which is followed by the cooking of the viand and ends with the preparation of the coffee. Given Steps / Procedure:Mother measures and washes the rice then sets the rice cooker to "cook mode". These actions take 5mins. Rice cooker is on cook mode for 30mins. Mother opens a can of processed meat, cuts this into 8 pieces and places the cut meat in a casserole. These actions take 5mins. The processed meat is boiled for 15mins.
