High-mix, low-volume and shared-resource operations
High-mix manufacturing consulting for complex product flow
Different routings, variable work content and shared equipment can make every order feel like an exception. Duggan helps high-mix manufacturers design how products move through the operation, with sequencing and response rules that reflect the actual mix.
Where Duggan can help
Connect the work that delivery depends on.
Design for the actual mix
Use demand, routes and work content to define families and their flow, including engineering-to-production handoffs.
Give priorities a clear basis
Connect sequencing and release decisions to the capability of equipment serving more than one value stream.
Make disruption actionable
Define normal flow, visible signals and agreed responses so people can recognize and address problems as they emerge.
The Duggan difference
Design the flow. Develop capability. Support implementation.
A Customer Delivery System defines how work moves to the customer: the connections between processes, the signals that show whether flow is on time, and the responses when it is disrupted.
Build the design around product families
Duggan considers demand, process routes and work content to define families and their flow. Low volumes and variety are design inputs, rather than exceptions to a standard production-line model.
Connect mixed-model flow and shared resources
The design addresses the designated scheduling point, sequencing and the capability of resources that serve more than one stream. These relationships give operating priorities a clear basis.
Make normal and abnormal flow visible
Defined signals and standard responses help people recognize when the system is drifting from its design. Education and implementation build the capability to sustain the flow and improve its response to disruption.
Variety is part of the operating design

- DemandVolume and timing

- Customer deliveryVisible performance
These are connected design considerations, not five independent improvement projects.
Connect leadership priorities to daily execution
Business and capacity decisions
For business leaders: connect delivery performance, capacity and growth decisions to a system that reflects the products customers actually buy.
Work that can move as planned
For plant and production leaders: establish how families share equipment, how priorities are signaled and how abnormal flow is handled.
Agree the measures before the targets
Lead time by family; on-time delivery; work in progress; shared-resource turnaround; schedule changes and recurring disruptions. Targets are grounded in demand and capability, not a generic productivity percentage.
Experience & method
High-mix manufacturing in practice
Duggan’s published Hypertherm case study describes connected manufacturing flow, visual signals and local capability in a high-mix operation. It illustrates how the operating system and employee development reinforce each other.
Read the Hypertherm case studyA focused starting point
A family of products crossing shared resources is a useful starting point. Discuss the mix, delivery gap and current scheduling burden to establish the appropriate design scope.
What an engagement can include
For engineer-to-order and assemble-to-order operations, particularly where in-house fabrication feeds assembly, the scope can connect engineering information, parts production and downstream delivery.
- Product Family Matrix and future-state Value Stream Design.
- Layout changes where needed, with an implementation plan.
- Mixed-model and shared-resource training, implementation support and progress reporting.
Continued involvement helps your people resolve practical issues while preserving the intended flow design.
Define the delivery gap
Discuss the work, customer need, constraints and available baseline with Duggan.
Design a connected scope
Agree the flow to examine, supporting functions and capability the operation will need.
Build and sustain capability
Connect education, implementation and review to the agreed operating design.

Can Lean work in high-mix, low-volume manufacturing?
Yes, when the operating design addresses variation in routes, work content and demand. Copying a repetitive assembly-line layout is not the starting point.
What is a product family?
For flow design, a family groups products with relevant process similarities. Commercial categories alone may not reveal how products should move through production.
Is this the same as the Lean Consulting service?
This page explains the application to high-mix operations. Lean Consulting describes the broader engagement, while Complex Machine & Fabrication provides more detail on the relevant production methods.
Should we redesign the facility first?
The required flow and resource capability inform the layout. Where a move or expansion is planned, those questions belong in the Facility Design scope.
