Fish Bone Chart Essay

ABSTRACTThe experiment aims to analyze the causes of each problem (effect) identified in altogether eggs and mayonnaise products during manufacturing and treat through the use of fish-bone plats or Ishikawa diagrams (cause and effect diagrams).Addition totallyy, dispersion compendium and work out smorgasbord type fish-bone diagrams were used. The result of the experiment showed that dish up smorgasbord diagram is more effective in pinpointing specific causes of error/ problems thus ease more in formulation of disciplinal actions to be taken. However, dispersion analysis concentrates more in analyzing the general nucleotide causes of the errors/ problems, thus fails to identify youngster causes of the problems.I. INTRODUCTIONA fish-bone diagram, also known as Ishikawa diagram or a cause-and-effect diagram, is an organized tool that helps manufacturers in identifying the realistic causes of quality problems (Forman, 2001). This optical tool is also used for organizing possibl e causes of defect in diverse categories. It has angled lines, or the bones, which represents a possible cause of error. each(prenominal) bone can have sub-bones which contains bring forward details about a possible cause of error. The bones ar joined together in a singular straight line that describes the main defect. This outline gives a shape similar to the bones of a fish, hence the name fishbone map as seen in Figure 1.Figure 1. Fishbone Diagram (Cinergix Ltd, undated)There be three main types of fishbone diagrams namely, the dispersion analysis type, product motion miscellany type, and the cause enumeration type. The dispersion analysis type organizes and fixs the factors that result in the difference among the product and other processoutcomes. The toil process classification type is made by making the steps in the production process be the major ribs of the fishbone diagram. It focuses on each step of the process to determine all possible causes of the error. In t he cause enumeration type, all possible causes that results to the defect is determined and then organized to show the relationships to the tone of product of process quality that is being examined (Florac, 1999).II. METHODOLOGYPrior to the exercise, the concourse identified and listed possible defects in both eggs and mayonnaise. One possible defect was then chosen for each the raw material (eggs) and the end product (mayonnaise). The possible defects chosen were cracked eggshells and unst able-bodied emulsion for the raw material and finished product, respectively. The group then constructed two types of fishbone diagrams ( sprinkling Analysis and influence Classification) for each of the chosen possible defects by identifying and writing its main causes and further causes in the diagram. The diagrams were then analyzed by the group to determine the root cause of the defects and to identify and suggest corrective actions to eliminate it. The effectiveness and capacity of the corrective actions were also considered and analyzed. The group then presented the diagrams to the class.III. SUMMARY OF RESULTS(See Appendix)IV. INTERPRETATION OF RESULTSDispersion analysis and process classification type of fishbone diagrams are used in the analyzation of the causes of the problems identified. Dispersion analysis cause and effect diagrams are structured in much(prenominal) a way that the factors contributing to the problem under say are classified into the standard six which are manpower, methods, materials, measurement, operators, and environments. Process classification diagrams on the other hand are structured in such a way that the factors are classified according to steps heterogeneous in the process (Brassard and Ritter, 1994). In the case of mayonnaise, some of the steps are sifting, mixing and filling. In terms of emphasis, dispersion analysis CE diagrams are advantageous in such a way that it helps organize and relate the factors that lead up to the pr oblem.However its drawback is that it may fail to identify humble causes that maybe overlooked (Omachonu & Ross, 2005). On the other hand, the advantage of process classification CE diagrams is that is easier to create because it follows the process in a product. However, verbiage may occur. Process classification is often used when the problem encountered cannot be isolated into a single department (Basu, 2011). An example of which is faulty milling machinery workers which may be a reoccurring problem in all steps.This makes it grievous to pin point what corrective action should be performed (Omachonu & Ross, 2005). Based on the exercise, it was observed that the use of process classification CE diagrams are more effective in being able to identify the specific causes of errors at heart a process however dispersion analysis CE diagrams were able to pinpoint general root causes of the problem by narrowing guttle the sources of errors into the standard six. General corrective a ctions can be generated use dispersion analysis CE diagrams but process specific corrective actions can be generated from process classification CE diagramsV. REFERENCESBasu, R.
