Steps of line balancing 1. Identify the work (job/task). 2. Break down the work into elemental tasks or steps. 3. List the various elements along with their precedence relationship or logical relationships and the time required. 4. Sketch the precedence diagram. 5. Determine the cycle time. 6. Divide the total time by cycle time to get the number of work stations required. 7. Assign task to stations or group the elements. Total time of all the elements in a group does not exceed cycle time.
