## Tree Diagram

Tags:

The tree diagram goes from general to specific, ie part of a general problem (the a troncoa ) and continuing with subsequent levels or causes (the a ramasa ). The causes in turn become problems for which it should associate causes and so on until the maximum possible level of detail or root causes. The action to resolve each case represents the means to achieve the overall goal, which is the solution of the problem. a Implementation Methodology The tree diagram is a tool for team work, so before you start, it is necessary to conform to the team (preferably interdisciplinary, with extensive knowledge in the subject) and assign a controller, which will lead the team through all steps to implement the tool.

Step 1: Establish the Problem The team must first determine the problem and written in a clear and specific to avoid the imprecision of the problem. In Table 4 we can see the correct and incorrect pose problems. Table 4. Form of correct / incorrect WRONG WAY problematic CORRECTLY Patients must wait long for treatment Patients should wait three hours for treatment There is much unemployment, 50% of young people leaving university did not get work shirts have The shirts are coming out flaws without buttons The more specific the problem is easier to find the causes and effects. Step 2: Define the causes or effects of the problem In a subsequent level records the root cause the problem. To identify this case you should use the question And why happens this problem?.

Not necessarily be a cause, may be manifold. Step 3: Define Each subsequent levels cause becomes the effect to identify new causes, which the team must continue to identify causes on until you reach the highest level of detail possible. Step 4: Weighing the importance of each branch to the causes of each problem is assigned a weighting in percentage (%) according to their importance. Step 5: Implement rollout solutions for each case in accordance with the priorities that emerge from their weighting. As an example, Figure 13 illustrates a finished tree diagram. a Benefits – Allows you to get an overview of the study object. – Allows identify the means to achieve a goal or solve a problem. – Allows identify the primary and secondary causes of a problem and prioritize the time to solve a problem. – Allows you to understand the cause a “effect of the problems. – Allows identify the objectives of each task goals.
