Let us take a slightly more. The previous example though involving only a single stage of decision illustrates the elementary principles on which larger more complex decision trees are built. Problem tree analysis also called situational analysis or just problem analysis helps to find solutions by mapping out the anatomy of cause and effect around an issue in a similar way to a mind map but with more structure.
Problem tree analysis is central to many forms of project planning and is well developed among development agencies. The main output of the exercise is a tree shaped diagram in which. Problem tree analysis helps stakeholders to establish a realistic overview and awareness of the problem by ing the fundamental causes and their most identify important effects.
Problem tree analysis procedure and example. Ideally the questions at the end of each branch of the issue tree should be simple yes no questions which can be answered through a short piece of analysis. Across the issue tree the whole point of the issue tree is to disaggregate a complex question into manageable chunks so make sure that your sub questions become progressively simpler.
They are favored at mckinsey because they 1 break problems down into manageable parts 2 enable solving the larger problem by solving the component parts 3 align the team on the nature of the problem and how to solve it and 4 provide insight into missing elements. Issue trees start with the problem statement and break it down into its component parts issues and sub issues. But it s not as good.
This structure is as mece as the last one. It almost feels it was put together mindlessly as if actually solving the problem wasn t a concern in the candidate s mind. Now here s an example of a mece issue tree for the same problem that isn t built with enough skill.
Trees have to be mece to avoid inefficient dependencies between branches. Use hypotheses when analyzing your issue tree to come quickly to the root cause. Be sure to differentiate two types of issue trees problem based or solution based.
An issue tree is the most important tool for structuring your case and form hypotheses.
Issue trees examples. For example one of the issue trees from chapter 2 was about improving the quality of new recruits in a consulting firm. Within making the selection better i could ve broken it down into stages 1 2 3 and so on of the selection process. Mckinsey issue tree example 1. Problem solving and decision making this report is solely for the use of client personnel.
No part of it may be circulated quoted or reproduced for distribution outside the client organisation without prior written approval from mckinsey company. An issue tree showing how a company can increase profitability. A profitability tree is an example of an issue tree. It looks at different ways in which a company can increase its profitability.
Starting from the key question on the left it breaks it down between revenues and costs and break these down into further details.
