Process Mapping

What Is Manufacturing Process Mapping?

Manufacturing process mapping is a visual way to document how work, material, and information move through a production process from start to finish.

The goal is to make the actual process visible—not just how it is supposed to work. A good process map can reveal delays, unnecessary handoffs, duplicated work, bottlenecks, rework, excess material movement, and steps that add little or no value.

What Process Mapping Looks At

Process Steps — What actually happens from the beginning of the process to the end?

Material Flow — How far does material travel, where does it wait, and how many times is it handled?

Information Flow — How do drawings, work orders, approvals, schedules, and other production information move through the process?

Handoffs — Where does responsibility move from one person, department, work center, or machine to another?

Delays & Queues — Where does work sit waiting for people, material, equipment, information, inspection, or approval?

Rework & Loops — Where does work repeatedly move backward through the process because something was missed, completed incorrectly, or requires additional correction?

Why Manufacturing Process Mapping Matters

A process can look efficient when each individual operation is viewed separately while the overall workflow is creating unnecessary time, movement, inventory, and cost.

Process mapping can help identify:

• Bottlenecks
• Excessive material movement
• Unnecessary handoffs
• Waiting time and queues
• Rework
• Duplicate or unnecessary steps
• Poor communication between departments
• Layout problems
• Opportunities for automation

When Process Mapping Makes Sense

Manufacturing process mapping is especially useful when:

• Lead times are longer than expected
• Work regularly gets stuck between departments or operations
• Employees have different understandings of the process
• Production problems keep recurring
• Material travels farther than it should
• Work-in-process inventory is building up
• A process is being redesigned or automated
• A new layout or piece of equipment is being considered

BrewerMade’s Approach to Process Mapping

BrewerMade focuses on documenting what actually happens on the manufacturing floor, not simply what the procedure says should happen.

The goal is to identify practical opportunities to simplify the process, reduce wasted movement and waiting, improve flow, and make better use of people, equipment, information, and floor space.
