Maintenance is continuous Development
Between 50% and 80% of global effort is spent on
“maintenance” !
18% Corrective(fixing reported errors)
18% Adaptive (new platforms)
60% Perfective(new functionality)
4% Other

Handling Moose
5 days to get up to speed
21 days to get proficient
Wednesday, August 24, 2011
Software engineers that extended Moose
Delphi/Java programmerscustomized modelsextended meta modelsdefined specific rules
Smalltalk programmers new tools to support code integration
Wednesday, August 24, 2011
Moose supports Your definition of quality/risk
Example(1) Getting bug maps(2) What info to collect?(3) How to present it?
Wednesday, August 24, 2011
Moose gives you the opportunity to control
your process.
