Replicated experiment has shown that while scripted and exploratory testing result in similar defect detection effectiveness (the total number of defects found) exploratory results in higher efficiency (the number of defects per time unit) as no effort is spent on pre-designing the test cases.<ref>{{Cite journal|last=Itkonen|first=Juha|last2=Mäntylä|first2=Mika V.|date=2013-07-11|title=Are test cases needed?
