rewrite : Systems thinking demonstrates three levels of thinking- events, patterns, and structures- explaining many systems. The first level, event, refers to watching single instances or occurrences of interest. Most firms mainly function at this level, solving problems individually without appreciating the root (Senge, 1990). The second level, patterns, recognises more lasting, continuing behaviours and gets at the issues. The last level, structures, is where systems thinking is at its deepest. At this level, one aims to discover why patterns occur and how structures, processes or mental models give rise to the observed outcomes in the System (Senge, 1990). What is more, by focusing on structures, organizations can more effectively work on those processes which result in the establishment of patterns of behaviour which are not as easy to alter
