2. Dynamic Feature Location
l Specifying modules based on the execution profiles
obtained using scenarios
– Lack of scenarios leads to insufficient results

3. Finding Clues for New Scenarios
l Which unexplored call dependencies ( )
should we focus on for preparing new scenarios?

l Measuring the potential impact of unexplored
dependencies
– NODU(dep): number of outgoing unexplored deps. = 5
