SC Capabilities required at various elements:

Supply requirements:
As number of offerings increases more raw materials are required. For example in this case this calls for additional inventory for fabrics, handle etc. more sourcing -

Supplier coordination and Information sharing:
Demand information sharing with supplier is required for efficient replenishment systems.

Manufacturing requirements:
Ordering system should be capable of generating dynamic designs/layout based on customer requirement (customizations) and transmit to the manufacturing unit along with the order details.
Since the customization is performed in the manufacturing line, workload has to be efficiently managed (either by having buffer stock between manufacturing cells or by having flexible workforce) since cycle times for each customization can vary.
Additional skilled workforce is required for the customization process
Extra equipment to perform the increased activities following the customization

Additional warehousing req:
Mass customizations can potentially result in increased work-in-progress inventory, so the warehouse/line store should handle these units along with the order details.
Since the customization increases the numbers of packages (finished goods), the warehouse management system should segregate and bin the orders in various customer racks.

Logistics/Delivery:
When the order becomes due or when the items against the order is completed, the tracking system should be capable (also to handle increased volume) enough to match the finished goods inventory to the delivery note.
The number of shipments are expected to increase as a result to customization, hence the logistics/shipping unit should be flexible enough to handle this.

Logistics/Transportation:
The manufacturer needs to coordinate with the logistics provider to ensure that the
