It is great posted by Jay Cross Whatever Happened to Performance Support? However, performance support is kind of old school. Who knows we do still rely on it . after reading Mr Jay's paper, i do understand how is performance support working on Electronic performance support systems. Is it training system for 21 centries? recently, company has to design a training system for their new employee. My qeustion is that do they relate each other. final, i found a answer from Cross. Thank you for your explanations.

For example, Cross stated that

"In her ground breaking 1991 book, Electronic Performance Support Systems, How and why to remake the workplace through the strategic application of technology",

Gloria described an EPSS as:
…an integrated electronic environment that is available to and easily accessible by each employee and is structured to provide immediate, individualised on-line access to the full range of information, software, guidance, advice and assistance, data, images, tools, and assessment and monitoring systems to permit job performance with minimal support and intervention by others.

Some people do not agree with it . For example, Marc Rosenberg, author of E-learning, former ISPI president, he is early proponent of performance support into system. He describes EPSS as “an enormous opportunity overlooked by the training community.” EPSS is not training, isn’t developed with the ADDIE model, and has been eclipsed by the new kid on the block: eLearning.

I was using ADDIE model to design digital library three years ago. it took me for one sememster to be done this job. i think EPSS can be disign by ADDIE. do you agree with it? Howwever, ADDIE may not work with E-learning system. i said may . some people still think ADDIE is working good with E-learning design.
