Environmental, social and economic challenges - EdexcelCost and manufacturing capability

When a product is developed, consideration should be given to social, economic and environmental issues, such as the materials used, the product life cycle and how it will be recycled or disposed of.

Cost and manufacturing capability

The cost of making any new product is affected by many different elements, and consideration should be given to each of these during design:

  • labour
  • equipment and manufacturing processes
  • materials, ie quality and finish
  • energy
  • overheads, eg rent, utilities, marketing, storage and business rates
  • environmental, eg how much is recycled and reused and the disposal of any waste both during and at the end of production

From this consideration a designer can set a realistic price for their product. If the price doesn't cover the costs to produce it won’t be viable as businesses can only make a profit if the price charged covers the production costs.

Example

To make a batch of garden sheds, a joiner has these costs to consider:

  • labour = 40 hours at £10.00 per hour = £400.00 per week
  • energy for the workshop = £95.00 per week
  • materials = £120.00 per shed

If one shed sells for £250.00, how many sheds need to be sold for the joiner to break even in one week?

Weekly costs = labour + energy

= £400.00 + £95.00 = £495.00

= £250.00 - £120.00 = £130.00

= 495 ÷ 130

= 3.8

Therefore, four sheds need to be sold to cover costs and show a small profit:

£130.00 × 4 = £520.00

£520.00 - £495.00 = £25.00

This yields a profit of £25.00 each week.

Question

In the production of dog kennels, the following costs are incurred:

  • labour = two workers for 40 hours at £10.00 per hour
  • workshop hire and energy costs = £300.00 per week
  • materials = £45.00

Each kennel sells for £200.00. How many dog kennels must be sold in one week to cover the costs of running the business?
