can someone draw a future state value stream map for this $-$ rban Haven Furniture $($UHF$)$

Urban Haven Furniture is a furniture manufacturer selling to retail stores. In the last few

years, the company has taken on a considerable volume. Resources have been assigned but

not with a production system focus. As a result, UHF has been receiving customer

complaints and hasn$$t been able to deliver on time.

After analysing the production and applying the principles of

Group Technology, UHF identified several product families.

This case concerns one product family $$ glass tables, which

come in small $($S$)$ and medium size $($M$).$

Customer complaints mostly relate to getting the wrong

components in their flat pack or the table being wobbly after

they assemble it$.$ Some of the customer complaints include the

following. $$I can't believe how unstable this table is$!$ One slight

bump and it wobbles like crazy$.$This table is a disaster

waiting to happen. During assembly, some of the screws stripped easily. Now, it wobbles

like crazy, and I$\text{'}$m worried it's going to collapse any minute$.$Some of the hardware was

missing, I wasn$$t able to assemble the table$.$

Furniture is a $$make$-$to$-$stock$$ business. It currently takes over a month to get through the

company production processes.

Production Processes

Tables are made of three parts $$ round glass, aluminium disc hardware, and timber legs.

While the glass is cut into a round shape, the discs are cut from aluminium coils. The

aluminium hardware is then glued into the glass.

At the same time, legs are made from wood lumbers. The wood is cut into standard pieces

and then shaped using a lathe. After sanding and coating, the legs are packaged together

with the glass $($and its aluminium hardware attached to it$).$ Finally, the flat pack is briefly

inspected to ensure all the components have been included.

$$ Tempered glass is supplied by CrystalCraft Glassworks every fortnight.

$$ Aluminium coils are supplied by AluCoil Producers every fortnight.

$$ Wood lumbers are supplied by ForestHarvest Wood on a weekly basis.
