• WinCC OA IDE is very good…• …but it took many years to get SVN integration

• CERN systems developed for 10 years• … and at least 20 years more foreseen

• Large systems• Several million lines of code

• Rotation of many developers• ~1300 ever (700 currently active)• Many different background• High risk of having “spaghetti code”

• Many languages• CTRL, C++, SML, PL/SQL, Python…

Why another IDE?
