1. Hierarchical structure

The FMEA, Control Plan,… have hierarchical structure forms. Before using them with FMEA Analysis, we need to understand their hierarchical structure.

1.1 Columns

First, like any other table, they have columns, each column has a header and items.

Columns and items of a hierarchical structure table

1.2 Column Relationships

But they also have relationships between columns and items

Relationships between columns and items of a hierarchical structure table

There are two types of column relationships:

  • 1-n relationship: one item of the left column has many (n) items of the right column. The left column is the parent-column and the right column is the child-column.
  • 1-1 relationship: one item of the left column has one and only one item of the right column. The left column is a master-column and the right column is sub-column.
Note
  • Root-column: the top-level column in the hierarchy of column relationship.
  • Master-column: include parent column and child column (also root column). These columns are marked with a checked green icon
  • Sub-column: it is a sub-column of a master column, there a no marked

2. Column requirement

Before setting up the form with FMEA Analysis, make sure that your form follows below conditions:

  1. All column’s header must be a single cell or merged cells.
  1. All columns are not a merged column.
