In the IT world, certification is given quite heavy weightage when it comes to beefing up your resume, however employers should be wary that a certification just means that the person knows about the best practises behind the certification standards but does not necessarily mean that they will make use of those skills.
For instance, I have come across PMP and PRINCE 2 certified professionals who have detracted far from what is preached by those standards. Some of them may have been restricted in the sense that they need to fit into the corporate culture, but others may just lack the necessary skills (both hard and soft skills) and are just hiding behind those pieces of paper.
Certification may be important, but it is not what defines the person. Ultimately, since IT work usually involves working closely together in teams, such cert-rich but skills-poor people will get exposed and lose their credibility.
