Customer Requirements Forecasting
According to the product snapshot (table 1), the target customers are supposed to be 10 audio product stores, 2 front-end manufacturers, and end users who directly order the products online. Their requirements for the product should be:
` 1) The audio product retails will need a medium quantity in the follow product types: 111,012,122,042,134;
2) The front-end manufacturers demand large quantity for a certain product type.: 042 for manufacturer 1 and 114 for manufacturer 2;
3) Each online order demands unique headsets, so I suppose each type has the same demand.
The monthly forecast requirements can be showed as the table below:
Target customer | Requirement description | Total quantity |
| Product Code | Quantity | |
Retail stores | 111,012,122,042,134 | 50×10 | 2500 |
Front end manufacturer 1 | 042 | 2500 | 2500 |
Front end manufacturer 2 | 114 | 2000 | 2000 |
End users | All types | 20 | 800 |
Total | | | 7800 |
Table 2 Monthly forecast requirements
The firm delivers the goods once a month to retails and front end manufacturers and once a week to end users’ orders. So weekly, at least 200 headsets will be produced. And I supposed the order of one month is manufactured within 3 weeks (Week1 for retail store orders, Week2 for manufacturer 1, Week3 for manufacturer 2).
According to production cycle, the productivity per week should be 2700 units.
Set the productivity of labor hour as 10 units per labor-hour.
The labor requirement is: 2700÷5÷8÷10=7 workers
