Direct answer
Redesign flow when transport distances, WIP and starving-and-blocking losses are significant relative to processing time. Quantify with a value-stream map before deciding.
When this decision arises
- Long internal transport distances between consecutive operations
- High WIP and long lead time relative to processing time
- Congested aisles and forklift traffic
- Departmental layout rather than product flow
- Frequent expediting and schedule changes
The options on the table
Value-stream mapping
Quantify value-adding versus waiting and transport time.
Cellular reorganisation
Group equipment by product family flow rather than by function.
Layout modification
Physical relocation to shorten flow, staged around production.
Scheduling change only
Where physical change is impractical, sequencing can capture part of the gain.
Engineering and project considerations
- Disruption during relocation must be planned and costed
- Utility and service relocation is often the largest cost element
- Flow redesign changes the constraint — re-measure afterwards
- Operator and supervisor involvement improves both design and adoption
- Some equipment cannot be relocated economically; design around it
What to prepare before engaging engineering companies
- Current layout with flow volumes and distances
- Value-stream map of main product families
- WIP and lead time data
- Utility layout and relocation constraints
What to measure
Frequently asked questions
Is layout change worth the disruption?
Where transport and waiting dominate lead time, yes. The gain is usually larger and cheaper than the equipment investment it displaces.
