Analysis and use of company level data

The standard requires tends in quality, operational performance (productivity, costs of poor quality, efficiency, effectiveness) and current quality levels for key product and service features to be documented. 

This requirement is similar to that in clause 4.14.3 under Preventive action since the data collected for preventive action serves a similar purpose. In one case an analysis of company-level data serves to identify overall trends and predict potential failures that will affect achievement of the goals. In the preventive action case, the data serves to identify local and overall trends and predict potential failures that will affect achievement of specified requirements for the product, process, and quality system. It would be sensible to develop a data collection and analysis system that serves all levels in the organization, with criteria at each level for reporting data upwards as necessary. You should not treat this requirement separately from that for preventive action since the same data should be used. However, the explanation given in clause 4.1.5 of Operational performance does include some factors that may not be addressed in your preventive action procedures. 

Productivity is addressed under Continuous improvement and in order to improve productivity you will need to collect data generally in the form of resource/part produced. Resource can be hours, costs, weight, or volume of material consumed. Graphs showing the productivity trend over time for plants, products, and processes would satisfy this requirement. 

Efficiency and effectiveness are broad terms that encompass the others. Productivity is a measure of efficiency and quality costs a measure of effectiveness, but there are others. Gustomer satisfaction is also a measure of effectiveness.
