Figure 4,2 An overview of different versions of the basic NMMS framework (see Figure 4,1), depending on the type of purpose.

The feedback loop in the basic NMMS framework should show whether a certain preferred action (according to the Classification/Action Matrix) had indeed an effect on the classification category it is linked with. This effect may be measured by looking at the relative occurrence of that specific error category in the near miss reports handed in during the period following the... 

The reason for placing Chapter 7 near the end was the fact that the NMMS framework modules as presented in Chapter 4 were used already extensively in structuring both the CEC-workshop discussions and conclusions, and also served as the basic checklist during the series of plant visits of the national survey therefore it seemed important to present the NMMS framework before Lhe results of Chapter 7. 

Figure 4.1 The seven modules of the basic NMMS design framework.

The basic version of the NMMS framework described above shows its functioning at the level of the safety department in an organisation. The learning process thus takes place at the level of "end-users" (e.g. operators, etc.), their direct supervisors and the local safety staff. Feedback loops which make this learning process possible are not. only the "evaluation" loop back to module 1, but also several smaller loops within the framework, e.g. when the purpose is modelling, module 6 may very well influence module 4, which in turn may change the ways in which the "input" modules 1,2 and 3 operate. 

Figure 4.1 shows the proposed basic framework, consisting of seven modules which together should form the "building blocks" for different types of NMMS s.
