From all the hype, you might think that interactive technology dominates the training market. But computer based training (CBT) and Web based training (WBT) have yet to match the popularity of traditional print, video and instructor-led programs.

Computer based training (CBT) provides multimedia instruction via CD-ROM on a desktop computer. Web based training (WBT) uses the Internet to deliver its message, but allows for greater interactivity through live chats with an instructor and bulletin boards.

CBT and WBT "chunk" up learning objectives, allowing students to skip between sections, work with simulations, take tests and receive immediate feedback. The buzzword for most CBT and WBT courses is "just-in-time" training - coaching that you can access in bits when and as you need.

These interactive methods are best for teaching complex material and technical certification courses. They're less useful for "soft skill" training like leadership, which requires a level of group interaction not yet possible with current technology like online chats.

Unlike CD-ROMs, Internet-based courses can be easily updated, are accessible from anywhere and work with all kinds of computer systems. But beware of technology constraints - the speed of your Internet connection could limit the effectiveness of online materials.

Before choosing a CD-ROM, ask the vendor for a complete version, not a sample disk, to check if the software is buggy or if it causes your office system to crash. And if employees are going to be accessing the CD-ROMs or online courses from their home machines, try to get a vendor who has a support line.

Most importantly, be mindful of your audience. Don't invest in high-tech training methods if your employees - and their supervisors - are uncomfortable using the technology.

Pricing models.

CBT and WBT costs depend on how many people will be trained. If you have a small number of workers to train, or if you anticipate employees taking a while to master the material, pay by the number of users. A CD-ROM costs upwards of $50 and can be used to train one user at a time. Online courses vary from $12 to a couple of hundred dollars per user, and some course providers let you refer to the material for a full year.

For larger groups, you can rent unlimited access for a limited time to a library of CD-ROMs. Or with the appropriate license, you can post a CD-ROM on your business' internal network for use by multiple users.

A less common alternative, known as "pay by use," lets you base your costs on courseware time used. This method may cause some people to rush through the material and is less desirable than paying by user or course.
