 installation and customization are simple for
  administrative task
 very good when it’s ready
 there are a lot of useful tools:
    Example: Click here
 gives lot and lot of integration
 gives good Web Site

    – SAP
    – Windows Server System (.Net and Windows
     Server 2003) [best for the smaller company]
           Conclusions(2)
 using WS, Don Sloan (Kforce) reduces the
  time required for its applicant matching
