Types Of Logic Trees

Question 1

Factor / Lever / Component logic trees

Answer 1

DESIGN:
Problem statement < lever 1,2,3 < sub-lever A,B,C

WHEN TO USE:
Early on when you don’t know about the underlying structure or can’t yet form hypotheses.

Question 2

Inductive logic trees

Answer 2

DESIGN:
(Think of components as end points)
Component 1,2,3,4 > other related components > problem statement

WHEN TO USE:
Early on when you know something about the end points of the problem but still don’t understand the underlying structure or relationship between the parts.

Question 3

Deductive logic tree

Answer 3

DESIGN:
Problem statement > relationship 1 + Relationship 2 > factor A + factor B

WHEN TO USE:
When you have a very clear idea of the problem structure especially when it is logically or mathematically coherent (e.g. return on capital trees).

Question 4

Hypothesis Trees

Answer 4

DESIGN:
Problems statement > hypothesis 1 OR hypothesis 2 OR hypothesis 3 > sub fact A + sub fact b, Assertion A + Assertion B

WHEN TO USE:
When you know enough about the structure to make clear hypotheses to begin to test with your data gathering.

Question 5

Decision Tree

Answer 5

DESIGN:
Problem statement -
If < yes,no < then outcome 1,2,3
