Cause and effect diagram

Cause and effect diagram What is a Cause-and-Effect Diagram? A cause effect diagram is a simple but very effective tool that helps to identify, sort, and display potential or real causes of a specific problem or quality characteristic. It can also be used to graphically illustrate the relationship between a given outcome and all the factors that influence the outcome. Because of its function of relating causes to their effect, it is referred to as acause-and-effect diagram. It is also called afishbone diagrambecause the design of the diagram looks much like the skeleton of a fish. It is also known asIshikawa diagrambecause it was invented by Dr. Kaoru Ishikawa (1915-1989), a Japanese consultant, and father of the scientific analysis of causes of problems in industrial processes. He first used this diagram in 1943 at Kawasaki Steel Works Cause-and-Effect Diagram is a tool that helps identify, sort, and display possible causes of a specific problem or quality characteristic (Viewgraph 1). It graphically illustrates the relationship between a given outcome and all the factors that influence the outcome. This type of diagram is sometimes called an Ishikawa diagram because it was invented by Kaoru Ishikawa, or a fishbone diagram because of the way it looks. When should a team use a Cause-And-Effect Diagram? Use cause effect diagram when you want: To identify the possible causes or the basic reasons, for a specific effect, problem, or condition. To sort out and relate some of the interactions among the factors affecting a particular process or effect. To analyze existing problems so that corrective action can be taken Constructing a Cause-and-Effect Diagram can help your team when you need to Identify the possible root causes, the basic reasons, for a specific effect, problem, or condition. Sort out and relate some of the interactions among the factors affecting a particular process or effect. Why should we use a Cause-and-Effect Diagram? A cause effect diagram helps to determine the causes of a problem or quality characteristic using a structured approach. It encourages group participation and utilizes team knowledge of the process. It uses an orderly, easy-to-read format to diagram cause-and-effect relationships. It increases knowledge of the process by helping everyone to learn more about the factors at work and how they relate. It indicates possible causes of variation in a process and identifies areas where data should be collected for further study. A Cause-and-Effect Diagram is a tool that is useful for identifying and organizing the known or possible causes of quality, or the lack of it. The structure provided by the diagram helps team members think in a very systematic way. Some of the benefits of constructing a Cause-and-Effect Diagram Helps determine the root causes of a problem or quality characteristic using a structured approach. Encourages group participation and utilizes group knowledge of the process. Uses an orderly, easy-to-read format to diagram cause-and-effect relationships. Indicates possible causes of variation in a process. Increases knowledge of the process by helping everyone to learn more about the factors at work and how they relate. How do we develop a Cause-and-Effect Diagram? When you develop a Cause-and-Effect Diagram, you are constructing a structured, pictorial display of a list of causes organized to show their relationship to a specific effect. Viewgraph 3 shows the basic layout of a Cause-and-Effect Diagram. Notice that the diagram has a cause side and an effect side. The steps for constructing and analyzing a Cause-and-Effect Diagram are outlined below. The application of cause-and-effect diagrams to the evaluation of thermodynamic data from UV-Vis absorption spectroscopic analysis is demonstrated. The contributions of measurement uncertainty identified from a cause-and-effect diagram are implemented into a Monte Carlo procedure based on the threshold bootstrap computer-assisted target factor analysis (TB CAT). This algorithm aims at an improvement of data comparability and accounts for non-normality, spectral, residual and parameter correlation as well as random noise in target factor analysis. The ISO Type-B measurement uncertainties are included into the process by normally distributed random numbers with specified mean values and dispersions. The TB CAT procedure is illustrated by a flow diagram and a case study of Nd(III) complexation by picolinic acid N-oxide (pic NO) in aqueous solution. Using 12 experimental spectra as input data, the single component spectra and the formation constant 1g betaML of the Nd(pic NO)2+ species a re obtained together with the respective probability density distributions. The role of the cause-and-effects approach on the further development of chemical thermodynamics is discussed Identify and clearly define the outcome or EFFECT to be analyzed Decide on the effect to be examined. Effects are stated as particular quality characteristics, problems resulting from work, planning objectives, and the like. Use Operational Definitions. Develop an Operational Definition of the effect to ensure that it is clearly understood. Remember, an effect may be positive (an objective) or negative (a problem), depending upon the issue thats being discussed. Using a positive effect which focuses on a desired outcome tends to foster pride and ownership over productive areas. This may lead to an upbeat atmosphere that encourages the participation of the group. When possible, it is preferable to phrase the effect in positive terms. Focusing on a negative effect can sidetrack the team into justifying why the problem occurred and placing blame. However, it is sometimes easier for a team to focus on what causes a problem than what causes an excellent outcome. While you should be cautious about the fallout that can result from focusing on a negative effect, getting a team to concentrate on things that can go wrong may foster a more relaxed atmosphere and sometimes enhances group participation. Identify, clearly state and agree on the effect or the problem to be analysed. A problem can be defined as a discrepancy between existing and a desired state of affairs. A problem exists when there is a difference between what should be and what is; between the ideal and the actual situation. Identifying a very clearly defined and specific problem is the first critical step to successfully implementing any problem-solving process. A symptom differs from a problem in that the symptom is an evidence of the existence of a problem Place a white board or flipchart where everyone could clearly see it. Draw a box containing the problem or effect to be analyzed, on the right side of the board with a horizontal spine. Add main categories of possible causes of the problem. Causes in a cause effect diagram are frequently arranged into the following categories: The 6 Ms:Machine, Method, Materials, Measurement, Manpower and Mother Nature (Environment) (recommended for manufacturing industry). The 8 Ps: Price, Promotion, People, Processes, Place / Plant, Policies, Procedures Product (recommended for administration and service industries). The 4 Ss: Surroundings, Suppliers, Systems, Skills (recommended for service industries). The Processes: Process 1, Process 2, Process 3 and so on. CAUSE EFFECT DIAGRAMS Cause and effect diagrams are very simple. The basic concept of a cause and effect diagram is to generate a fishbone diagram where all the causes of a problem against the effect (the effect is the fishes head with all the scales of the fish being the causes) Cause and effect diagrams are best generated in brain storming sessions, when you are talking to the operators about making improvements. You can use them to view historical attempts at solving quality issues have worked out, get the operators involved, see if your proposals for improvement will work or not. Cause and effect diagrams are useful; a lot of organizations do use the diagrams on quality control documents such as concession sheets where a cause and effect diagram must be completed every time there is any defective material. These diagrams would then be analyzed on a regular basis, to bring about improvements in product build. FUTURE STATE Develop a future state where you want your business to develop. By mapping the process, we should identify areas for improvement. By looking at rank order we observe further areas for improvements. Using cause and effect diagrams we see what has worked and what has not. The final state is to review and apply all we have learnt to how we get to where we want to be. There are numerous other methods for analyzing your business for improvement, the above examples are for illustration purposes only, please be sure to read other quality publications. Understanding Errors The major underlying principle in all quality management systems, is to understand what causes errors in business and try to rectify and prevent them occurring again. Errors can be attributed to: Poor training, which leads to mis-understanding and lack of perception. Production cycle based upon the use of time saving measures which result in poor product quality. Incorrect procedures covering the entire production cycle, rather than specific processes. Employee intentional action (as a result of poor labour relations, motivation, etc). What quality systems aim to achieve by a reduction in errors: Proper identification of production process. Understanding how errors arise, and what could happen. Put measures in place to prevent the errors occurring again. Having unstable processes in the production cycle leads to high levels of non-conforming material, which in itself leads to greater waste in the work place and lack of teamwork. Extensions to this are that your business will find itself having little or no direction, reduced profits due and lots of angry customers. REFERENCES: Brassard, M. (1988).

Changing Self Essay Essay

How do composers use texts to explore concepts of Changing Self? Discuss ideas and techniques. In Gwen Harwood’s poems Prize-Giving and The Glass Jar, the prescribed text Sky-High, and the novel White Teeth by Zadie Smith, the composer have used many varying ideas and techniques to investigate and illustrate concepts of Changing Self effectively. The ideas looked at in Gwen Harwood’s poetry include imagery, retrospect, metaphor, and inversion of the connotation of adjectives. Ideas conveyed in Sky-High include imagery, retrospect, and comparison. The techniques and ideas in White Teeth, to name the most important, are long and erratic chronology, removing characters for a period and the exposing of the least important change are evident in the texts that are compared. In Gwen Harwood’s poem Prize-Giving, the composer has adeptly used imagery to examine and represent the Changing Self evident in this poem. This striking imagery at first portrays an egotistical middle aged man, such as his inurbane behaviour when he â€Å"scowled with violent distaste†. This works in revealing the major change of Eisenbart, in comparing the self-righteous man at the start of the poem, to the awkward and confused man at the end. The imagery used to describe the titian haired girl is also evocative, especially when comparing her supposed insignificance in contrast to Eisenbart, and the affect she has on him. She seems to be nothing but a cheeky, though attractive, schoolgirl: â€Å"one girl sat grinning.† This thought of her insignificance is reinforced when she â€Å"winked at nearby friends†, possibly reinforcing to Eisenbart her immaturity that was earlier established through her audacious behaviour during the opening prayer. However, Eisenbart was flung from his â€Å"calm age and power† merely by a touch of this ‘immature schoolgirl’, indicating a change. This change in the girl’s attitude is reinforced when she changed â€Å"her casual schoolgirl’s for a master’s air†, indicating the power that she has that Eisenbart has not detected thus far. In the text Sky-High by Hannah Robert, the concept of Changing Self is analysed and emphasized through retrospect, apt imagery, and change of language. â€Å"The best climbing tree† indicates the experiences of a child and their joy in everything no matter how small. However, the responsibility in the statement â€Å"it is unlikely the washing line could support me† divulges that the persona is now more responsible, and, it is discovered, also older, revealing a physical change of self. The comparisons in the final stanza show the insight that the persona now has; as seen in â€Å"I was once the curious onlooker, I now write my own semaphore secrets in colourful t-shirts†. It also shows, however, that no matter how much a person changes, that he or she is still the same person, and that they still retain what they were before. The metaphors used in The Glass Jar, and the way in which they are developed and often exaggerated, shows and typifies the change of self that is experienced by the persona, so that greater audiences may understand the experiences of a small child. Only a small child could imagine an ordinary glass jar as a â€Å"monstrance† in which the sun could be caught for the night. This vision of the â€Å"holy commonplace of field and flower† coming to save the boy is lost when he awakes from his nightmares. The religious metaphor is now lost except for the mocking image of the â€Å"resurrected sun† in the final stanza. The inversion of the usual use of adjectives shows the confusion associated with the change of self for the persona, such as the â€Å"malignant ballet†. The novel White Teeth, by Zadie Smith, develops the concept of Changing Self with a long and somewhat inconsistent chronology. All the characters in this novel, which reaches from World War Two to the end of the century, obviously change physically due to this long chronology. However, the retrospect as to how much the characters have changed in other ways is far more potent because of the extensive chronology. The comparison, for example, Josh Chalfen turning away from his family and becoming less of a nerd: he was the kind of guy â€Å"who could measure an eighth with his eyes closed (so fuck you, Millat)†. The original focus of the book on Archie Jones beguiles the reader into thinking that he is the main focus for the book. However, Archie serves  merely as a connection between all the original characters. From these characters the Jones, Iqbal, Chalfen and Bowden families and their stories emerge, and all the adults, in the end, only accentuate the changes that the children (Irie, Millat, Magid, and Josh) undergo, that is, comparing where the children have ended up to what their parents expected of them. The later and extended focus of the novel on Millat Iqbal, who changes in the most radical way out of all the characters, hides the slow and, in the sense that Millat changes, insignificant changes of Irie Jones, but her changes are more symbolic and emotional. The removal of Magid from the story means that his change of self seems sudden, because the persona is taken away at the age of nine years and only returned at the age of seventeen. In the texts Prize-Giving and The Glass Jar by Gwen Harwood, Sky-High by Hannah Robert, and White Teeth by Zadie Smith, ideas and techniques are flaunted in terms of how they are used to display the change of self in the personas. The numerous ideas used in each of the texts, often overlapping to be used in more than one text show the skill of the composers and their flexibility in applying various techniques.

What the difference between big data and data? Figuring out these two questions can help us to comprehend big data in depth. Big data has been defined as the data that is too big to be analyzed by traditional methods. Generally speaking, there are five characteristics for big data: data volume, data variety, data velocity, data variability, and data complexity, which were also known as the five dimensions for big data.3 Data volume means that the measurement of the units of data storage. Data variety indicates the diverse forms of data. Data velocity has been defined as the velocity of data producing and processing. Data variability means that the data flow could be inconsistent. Data complexity indicates that the data is hard to analyze. Also, the five dimensions of big data can be seen as the differences between big data and data. Figure 1.13 shows the dimension diagram for big data. Figure 1.1 Dimension diagram for big data Reproduced from reference 3 No matter if you are looking at data or big data, it is no value without analysis. So if managers really want to use big data to create
