overview of the relationship between the basic elements ‘plan’, ‘concept’ and ‘technique’

  • A strategy consists of a number of concepts. There are 17 strategies in BOSS.
  • A concept is a task which must be fulfilled by the soil remediation system; a concept can be realized by several techniques (‘or’ relation). One technique can be applicable for several concepts. There are 57 concepts in BOSS.
  • A concept can be executed by a number of techniques (‘OR’ relation). A certain technique can be used under several concepts. In total there are 101 techniques in BOSS.
