Fig. 1 Implementation of Indicators in an iterative process
“practical target indicators”. The practical target indicators are a set of 21 indicators
in total (see Table 2). For the assessment of the case examples the indicators were
divided into the three sustainability dimensions.
Since the concept of sustainability is in transition over influenced by culture and
knowledge a regular reassessment is vital. That is why an incremental implementation of indicators is proposed (see Fig. 1). By adding indicators over time, the MIS
can be readjusted, and new indicators can be added if necessary.
