$5$d$.$ CVS PSI has collected a few items of information and data on the above flow. On the surface most of the data appear to contribute to the KEY problem. These may be too obvious $($top of the iceberg$).$ But there are only $2$ probable and feasible non$-$obvious causes of problem $($listed on pages $7-8$ that can be $$real causes$).($i$)$ Identify the $2$ and provide reasons why only these $2$ can be primary factors behind the problem. $($ii$)$ Provide granular$/$specific statistics$/$numbers and behind the choice of these $2$ factors being the only possible non$-$obvious cause of the problem. $($Note there are several problems listed but most can not logically cause the problem and its recurrence$).$
