Abstractness • Indic a tes whether: ( a ) the item is m a inly a bstr a ct (interf a ces, a bstr a ct cl a sses – extensible but not directly us a ble); or (b) it is m a inly concrete (implement a tions – directly us a ble but less extensible). • It is a v a lue between 0 a nd 1: 0 ( a concrete cl a ss or a p a ck a ge with only concrete cl a sses) 1 ( a n a bstr a ct cl a ss/interf a ce or a p a ck a ge with only a bstr a ct cl a sses/interf a ces) 26

Instability • Indic a tes whether: ( a ) the item is m a inly used by others (st a ble – h a rd to ch a nge); or (b) it m a inly depends on other items (in-st a ble – ch a nge a ble). • It is a v a lue between 0 a nd 1: • 0 only incoming dependencies to • 1 (only outgoing dependencies). 27
