DIAGRAM of tree definition the tree diagram is a tool used to sort graphically and structured the various actions that should be carried out to reach a goal or solve a problem. The tree diagram is going from general to specific it, i.e., part of a general problem (the trunk) and continues with subsequent levels or causes (the branches). The causes are converted to turn on problems which should be associated causes and so on until reaching the maximum level of detail as possible or primary causes. Action to resolve each case represents the means to achieve the overall goal, which is the solution of the problem. Ford Motor Company has plenty of information regarding this issue. Methodology of implementation the tree diagram is a tool of teamwork, therefore before you begin, it is necessary to form the working team (preferably interdisciplinary and broad knowledge in the subject) and assign a responsible thereof, who will lead the team through all the steps to apply the tool. Step 1: Establish the problem the team must initially determine the problem and write it clearly and specifies to avoid the imprecision of the problem.
Table 4 demonstrates the correct and incorrect form of pose problems. Table 4. Form of correct/incorrect problems correctly incorrect form the patients must wait a long time to be served patients should to wait 3 hours to be served there is much unemployment 50% of young people who drop out of College unable to work shirts have faults shirts are coming out without buttons while more specific the problem is more easy it will be to find the causes and effects. Step 2: Define the causes or effects of that problem in a subsequent level recorded the cause that causes this problem. To identify this cause it is recommended to use the question why it happens that problem?.
It should not necessarily be a cause, they can be multiple. Step 3: Define the later levels each cause becomes in effect to identify new causes, by which the team should continue identifying causes successive until it reaches the highest level of detail as possible. Step 4: Weigh the importance of each branch to the causes of each problem is assigned a weighting in percentage (%) according to their importance. Step 5: Implement solutions are deployed solutions for each cause according to the priorities that arise from their weighting. By way of example, a finished tree diagram is illustrated in Figure 13. Benefits – Allows to obtain an overview of the object of study. -Identifies the means to achieve a goal or solve a problem. -Lets you identify primary and secondary causes of a problem and assign priorities to the time of solving a problem. -It allows to understand the relationship cause effect of problems. -Identifies the objectives the goals of each task. Relationship with other tools – affinity diagram.
