Time and cost still important?

This morning, two students at Ghent University have compared the use of ProTrack with various other project management methods and have concluded that ProTrack is "an ideal tool to control time and cost of a project when these two objectives are important".

Glad to hear this good ProTrack news from someone else... but are the time and cost objectives still important?

I believe they are... 

As an example, the London 2012 summer Olympics are on course to be the most over-budget games for 16 years after organizers failed to forecast demands for security and private investment, according to a study by the University of Oxford (read the full article here).

They should have used ProTrack, don't you think?
