For wire harness assemblers, the key to profitability lies in the ability to produce harnesses at a competitive and well-understood cost. This is a difficult challenge, because project time scales and margins are continually squeezed, while variables such as design content and copper prices can change rapidly.
Engineers have several wire harness costing options available. Many small- and mid-sized harness shops rely on spreadsheets, which are inexpensive to purchase and run. They are readily available and familiar to millions of people.
