Pretend that you have just come from a relative's wedding reception. It didn't turn out as well as it should have, and the bride's parents are pretty mad at how things turned out

Use the supplied template to construct a conventional cause-and-effect diagram. Identify twelve sources of defects for the issue "dissatisfied customer of wedding reception caterer." (Your dozen need not be exactly three per main cause, but should be a balanced treatment.) Categorize each cause onto a main cause. Provide brief support for each of your choices.

Solution: Individual responses may vary considerably; some of the variation in responses comes from differing views of what is the caterer's realm of responsibility, compared to what might be assigned to a wedding planner instead. Material: not enough plates, glassware, utensils; prepared wrong dish; food was cold; ran out of food; food was "bad." Machinery: air conditioning/heating was broken; room was dirty; room too small; furniture poorly arranged; wedding "props" ugly or shopworn. Method: not on time; overcharged; not enough workers. Manpower: wait staff not properly attired; wait staff not speedy; wait staff not courteous. Responses should comment as necessary to show why a fault lies on a certain main branch; as an example, "cold food" might be interpreted as Method, not Material.
