Fabrication
The fabrication process outlined below is how RayDesks plans on producing our ergonomic desk riser. Each unit is composed by metal and non metal parts which majority made in house. There is 10 different types of machines used during this process. As explained by the Materials Analyst, all metal parts consist of steel sheets, rods, and tubes that go through the laser cutting, bending, and welding. After being shaped and connected, all metal parts go through the painting process. The painting process consists of the parts going through the parts washer, then is moved into the spray booth and is sprayed with paint from a paint gun, finally it is moved into the oven to cure. The non metal parts are made from ABS (Acrylonitrile Butadiene Styrene), Silicone Rubber, and Polyacetal. All plastic parts are made in the injection molding machine. Below is a chart representing the quantity, source, and prices of each machine selected.
The total capital expenditure for fabrication equipment in year one is $399,017.

Assembly
The Methods Analysis that was preformed by RayDesks is based on 14 total production hours that are split into two 7 hour shifts. This analysis includes the recommended number of workstations needed during assembly of the desk.
Takt and Standard Time
The takt time for our facility is 65 seconds. This was calculated through 250 working days in a year, 14 hours of production time, and year 5 production volume of 195,000 desks. The total cycle time for assembly is 248 seconds. Three allowances were assumed for the assembly of the adjustable desk and total to 12%: 5% for personal allowance, 3% for delay allowance, and 4% for fatigue allowance. This makes the total standard time for assembly to be 278 seconds.

Workstations
Through calculating Workstations based on takt time and standard time, the number of workstations needed is 5. Operation 1 has a higher operation time than the takt time, therefore has been split into parallel workstations between workstation 1 and 2. As seen in the table below, the efficiency for workstation 2 is infeasibly high at 99.26% and workstation 5 is unsatisfactory at 53.42%. Due to these numbers, workers from workstation 5 will spend their idle time assigned to loading finished goods onto pallets and one hour per shift assisting workstation 2.
The final assembly operation efficiency is 85.59%.

Capital Costs and Annual Expenses
The additional equipment needed for assembly is workbenches, anti-fatigue mats, tape guns, and staple guns. This totals to a capital cost for assembly in year 5 to be $9,858. A further breakdown of capital costs can be found in the table below titled "Capital Costs". The annual expenses based on year 5 demand include packaging tape, staples, small cardboard boxes, large cardboard boxes, biodegradable packing peanuts, large bags, small bags, instruction pages, and Allen wrenches. The total annual expenses are $1,400,750. A further breakdown of annual expenses based on year 5 demand are stated in the table below titled "Annual Expenses According to Year 5".
