Routing Use Cases: How Manufacturers Turn Process Knowledge Into Repeatable Execution

Every product has a path through the factory. It may start with cutting, move to machining, then welding, finishing, inspection, packing, and dispatch. Another product may need outside processing, heat treatment, assembly, testing, and final QC. If this path is not defined clearly, production depends too much on individual memory.

Routing is the structured definition of that path. It tells the factory which operations are required, in what sequence, at which work centre, with what expected time, and sometimes with what tools, labour, or inspection steps.

For manufacturers using AICAN Optiwise, routing helps connect production planning with shop floor execution, costing, capacity, and progress tracking.

Use Case 1: Defining Operation Sequence

The most basic routing use case is operation sequencing. The system defines the correct order of steps needed to manufacture a product. This reduces confusion, especially when products have multiple processes or variants.

For example, if drilling must happen before coating, and coating must happen before final assembly, routing makes that sequence visible. New supervisors, operators, and planners do not have to depend only on verbal instructions.

Use Case 2: Work Centre Planning

Routing links operations to work centres or machines. This helps planners understand where work will happen. If many jobs require the same work centre, the planner can see potential bottlenecks.

Without routing, production planning may list jobs but not show the load on each machine. Routing turns the plan into a more realistic capacity view.

Use Case 3: Estimating Production Time

Each routing step can carry setup time, run time, queue time, or labour time. This helps estimate how long production will take. Even if actual time varies, planned time gives the business a baseline.

This baseline supports delivery commitment, capacity planning, and cost estimation. Over time, comparing planned versus actual time can reveal process improvement opportunities.

Use Case 4: Costing Operations

Material cost is only one part of product cost. Manufacturing also includes machine time, labour, outside processing, inspection, and overhead. Routing helps assign process cost to the product.

If one product uses a high-cost machine for three hours and another uses it for thirty minutes, costing should reflect that difference. Routing gives structure to this calculation.

Use Case 5: Shop Floor Tracking

Routing can help track where a job currently is. Has cutting finished? Is machining pending? Is the part waiting for inspection? Is assembly complete? This visibility matters when customers ask for status or management reviews delays.

Instead of saying “production is going on,” the team can identify the exact operation and bottleneck.

Use Case 6: Quality Checkpoints

Some operations require inspection before the next step. Routing can include QC checkpoints so quality is not treated as an afterthought. For example, dimensional inspection after machining may be required before assembly.

This prevents defective work from moving too far downstream, where correction becomes more expensive.

Use Case 7: Outside Processing and Subcontracting

Many manufacturers send material outside for coating, machining, heat treatment, fabrication, or specialised processing. Routing can include these external operations, helping teams track what was sent, what is pending, and what returned.

This is important because outside processing often creates visibility gaps. AICAN Optiwise can help connect routing with subcontracting and stock movement workflows.

Use Case 8: Standardising Repeat Work

When routing is documented, repeat products become easier to plan and execute. The factory does not rebuild process knowledge every time. This is especially valuable when experienced people are absent or when production volume grows.

Routing also helps train new team members because the process is visible in the system.

Common Routing Mistakes

The first mistake is making routing too theoretical. If the route does not match shop floor reality, teams will ignore it. The second mistake is not updating routing after process improvements. The third is missing outside operations. The fourth is ignoring setup time, which can distort capacity planning.

Routing should be maintained as a living production record.

Where Optiwise Helps

AICAN Optiwise helps manufacturers connect routing with BOM, production planning, work orders, capacity, costing, QC, and subcontracting. This gives teams a clearer way to plan and track how products move through operations.

Routing is not just documentation. It is the operating path that helps production become repeatable.

Founder’s Note

At AICAN, we often find that factories know their processes very well, but the knowledge sits in people’s heads. That works until volume grows, people change, or complexity increases. Optiwise helps convert that process knowledge into a system the whole team can use.

FAQs

What is routing in manufacturing?

Routing defines the sequence of operations, work centres, and time required to manufacture a product.

Why is routing important?

It improves production planning, capacity visibility, costing, shop floor tracking, and process consistency.

How does routing support costing?

Routing can assign operation time, machine time, labour, and outside processing costs to products.

Can routing include subcontracting?

Yes. External processes can be included in routing so outsourced operations remain visible.
