3. 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). 3
4. Distance 4 Abstract Concrete Stable Hard to Change Only incoming dependencies Unstable Changeable Only outgoing dependencies the m ain sequence Painful Useless 0 1 1 0 Instability Abstractness
5. Structural Metrics Distance
6. Distance • Dist a nce: how f a r a p a ck a ge is a w a y from the M a in Sequence • D = A + I – 1 • V a lues -1 to 1 • Absolute Dist a nce |D| 6
