Software modifications and reliability ARW2011

Software is a major part degrading reliability Software is major part able to improve reliability

Severals steps Collect data on software behaviours Sort, priorize data and convert in specifications Process of developpements Process of information before upgrading Process of integration, tests & installation Process post installation

questions Timing for update and upgrades ? How do you define the kind (and depth) of tests ? Management of softwares interfacing ? Do you have off-line platforms ? level of documentation ? Training of operators, backup solutions ? Good and bad stories ?

naming Patches, update, upgrades, renovation Software is: code ? O.S. ? Machine ? IT ? control ? Scada ? Middleware ? Developpers ? Testers ? Integrators ? Users ? Configuration managers ?
