Tool description

The Gozinto chart is a vertical tree diagram that displays hierarchical levels of detail of a complete product assembly to ship process. Developed by A. Vazsonyi, this project planning tool is of great value for kitting, bill of materials (BOM) auditing, parts/number identification, and operator training.

Typical application

To breakdown a product into its parts.

To flow out the assembly process.

To cross-reference parts data with the hierarchical levels of assembly.

Problem-solving phase

Notes and key points

Gozinto chart numbering is by levels and BOM or part identification number. Example: 3015: 3 for level 3, 015 for bill of material or part ID number.

This is a similar approach to the work breakdown structure (WBS) chart.

Step-by-step procedure

STEP 1 List all parts required to completely assemble the product.

STEP 2 Draw a hierarchy of assembly, showing levels of detail from the top down to the basic level of parts.

STEP 3 Provide identification of parts; name and number each part charted.

STEP 4 Check completeness of chart and date.
