Turning inputs 投入 into outputs 产出
- Every business takes things in — materials, labour, machines — and turns them into something customers want.
- That transformation 转化 is operations 运营, the engine room of the firm.

Operations is the transformation of inputs into outputs.
Materials, labour and capital used in production are the ______ of operations.

Inputs are transformed into outputs.
The transformation process
- Inputs (materials, labour, capital) → process (the transformation) → outputs (goods or services).
- Operations management makes this flow efficient and reliable.
Operations turn inputs into outputs, adding value
Operations: input → output
Operations management turns inputs into finished goods or services through a transformation process.
6 workers produce 480 units. What is labour productivity (units per worker)?

480 / 6 = 80 units per worker.
Efficiency in operations means:
Difficulty 1/5 · 100 coins + a small bonus on first completion today
Efficiency minimises resource waste.
Effectiveness is about actually meeting the objective, such as quality and on-time delivery.

Effectiveness = achieving the goal; efficiency = doing so without waste.
Productivity 生产率, efficiency 效率, effectiveness 有效性
- Productivity = output ÷ inputs (e.g. output per worker).
- Efficiency = producing with the least waste of resources.
- Effectiveness = actually meeting the objective (quality, on time).
Worked example. A bakery makes 600 loaves with 5 bakers → labour productivity = 120 loaves per baker. Buying a better oven lifts output to 750 with the same 5 bakers → productivity rises to 150.
A distribution centre: operations management moves inputs through to finished goods
Operations objectives
- Keep costs low, quality high, delivery reliable, and stay flexible.
- Increasingly, operations must also be sustainable 可持续的 (less waste, lower emissions).
You've got it
- operations transform inputs → process → outputs
- productivity = output ÷ inputs; efficiency = least waste; effectiveness = meeting the objective
- operations aim for low cost, high quality, reliable delivery and flexibility
