Advantages and Disadvantages

Web-based training may be compared to current implementations of computer-based training (CBT) in quality of training outcomes. But what advantage would a training vendor have in establishing a web training site versus producing a CD-ROM or client/server-based training system? What considerations would favor CBT over WBT? Let’s look at some of the advantages and disadvantages of WBT.

Advantages

• easy delivery of training to users
• opportunities for group training (asynchronous and synchronous) as well as individual training
• multi-platform capabilities (Windows, Mac, UNIX, PDA, phone, other wireless devices)
• easy updating of content
• quicker turnaround of finished product
• requires less technical support
• billing options by user ID, number of accesses, date/time of access
• access is controllable
• options for installations on private networks for security or greater bandwidth
• options to link with other training systems
• multitasking capability suitable for electronic performance support systems (EPSS)
• vast market for distributed training
• growing level of acceptance

Disadvantages

• bandwidth/browser limitations may restrict instructional methodologies
• limited bandwidth means slower performance for sound, video, and intense graphics
• someone must provide server access, control usage, bill users
