Figure 8
The diagram is structured into five main categories: Man, Material, Method, Environment, and Equipment, each with sub-causes leading to customer service delays. Under Man, factors include demanding customers, insufficient training, lack of technical knowledge, inadequate time for rest, and lack of staff. Material issues involve wood shredding, wrong size selection, and order mistakes. Method-related causes include similar descriptions, different suppliers, time-consuming processes, large orders, orders requiring visits to both warehouses, unclear definitions of work obligations, insufficient communication between sectors, unnecessary tensions, stock problems, and sales mistakes. Environment factors encompass product arrangement, accessibility problems, unclear responsibilities, unnecessary staff movement, power outages, and system overload. Equipment issues are attributed to old equipment and difficulties in buying new equipment.Cause and effect diagram for the customer service delay. Source: Authors' own creation
