oPRODUCTION SYSTEM
A first possible distinction in production systems (technological classification) is between process production and part production. * Process production means that the product undergoes physical -chemical transformations and lacks assembly operations, therefore raw materials cant easily be obtained from the final product, examples include: paper, cement and nylon. * Part production (ex: cars and ovens) comprises both manufacturing systems and assembly systems. In the first category we find job shops, manufacturing cells, flexible manufacturing systems and transfer lines, in the assembly category we have fixed position systems, assembly lines and assembly shops (both manual and/or automated operations)

Metrics: efficiency and effectiveness
Operations strategy concerns policies and plans of use of the firm productive resources with the aim of supporting long term competitive strategy. Metrics in operations management can be broadly classified into efficiency metrics and effectiveness metrics. Effectiveness metrics involve: 1. Price (actually fixed by marketing, but lower bounded by production cost): purchase price, use costs, maintenance costs, upgrade costs, disposal costs 2. Quality: specification and compliance 3. Time: productive lead time, information lead time, punctuality 4. Flexibility: mix, volume 5. Stock availability
A more recent approach, introduced by Terry Hill, involves distinguishing competitive variables in order winner and order qualifiers when defining operations strategy. Order winners are variables which permit differentiating the company from competitors, while order qualifiers are prerequisites for engaging in a transaction. This view can be seen as a unifying approach between operations management and marketing.
Productivity is a standard efficiency metric for evaluation of production systems, broadly speaking a ratio between outputs and inputs, and can assume many specific forms, for example: machine productivity, workforce productivity, raw material productivity, warehouse productivity (inventory turnover). It is also useful to break up productivity in use U
