Today enterprises focus on down time losses, especially breakdowns.
Many losses are not focused enough today i.e. planned downtime, cycle time losses and minor stoppages.
It should be beneficial to change focus and use a comprehensive model of losses.
The latest TPM model with eight equipment losses seem to be the most relevant in general.
The data collection problem is not sufficiently treated in the TPM literature.
It might be a risk that TPM-thinking tries to avoid the data collection problem,by going directly towards operator maintenance and small group activities without investigating the configuration of losses.
This might lead to operator maintenance and small group activities without effects on overall effectiveness.
A suggestion for solving the data collection problem is to start with the simplified fens-model.
When the personnel has received data collection experience it is possible to go over to a full OEE model.
We suggest a method for collecting disturbance data, where computerized systems are combined with manual recording. This gives both an exact assessment of the magnitude of the disturbance and a deeper understanding of the reason for losses.
