The posterior parietal cortex is located posterior to the somatosensory cortex and serves as its unimodal association area. In addition to further processing of somatosensory input, information from the somatosensory cortex is integrated with visual inputs in this region. Association tracts from both the somatosensory cortex and the visual cortex terminate here. This activity is important for planning complex movements and for hand (prop-rioception)-eye (visual) coordination. 

The case study problem described in the preceding section is characterized by a high degree of planning complexity. 

Theses hierarchies and levels again can be found in the chemical industry practice, but may differ by wording or aggregation levels in different industries or even in other companies. Key is that object and hierarchies are an important aspect in planning in order to limit planning complexity and to ensure decision significance. 

Despite our increasing knowledge of the structures and reactions of organometallic intermediates, it is virtually impossible to plan complex ionic reactions by using known rate constants from simple model systems. Rate constants are potentially more useful when planning pericyclic reactions because they are easier to measure and because pericyclic reactions are much less susceptible to medium effects than ionic reactions. However, the need to evaluate the rates of competing pericyclic reactions is relatively rare (often there is only one reasonable possibility).

When planning complex man-machine-environment-systems, the natural equipment of the operator, namely man, will have to be taken into account with some of his specific psychic and physical functions and the possibilities of compensating for them, and in some cases minimum values will have to be established. The science called ergonomics deals specifically with the problems of workplace design as far as creating humane working conditions, the proper performance of the technical system, and improved safety in the workplace are concerned.
