designers must prepare a business case to persuade management that an EPSS
will address their performance needs, and the expenses saved or revenues generated more than compensate for the cost of development.
IBM's John Karat describes his view of EPSS
research from the neighboring field of user-centered design.
The low-fidelity manikins were set up with appropriate props, and the students used the EPSS
, SDS, and Student Satisfaction and Self-Confidence in Learning Questionnaires to evaluate the program.
Similarly, to the extent that there are identifiable context elements that distinguish electronic performance support systems from other software systems (such as a user's need to perform adequately on the first day of use), then I think it makes sense to advance EPSS
and to explore the usability approaches particularly applicable to it.
Design for EPSSs
operates on many levels: the process (or order in which design decisions are made); the technical details (that is, choosing the technologies used to create parts of the EPSS
and deliver it to users); and the creative, ethical, and philosophical elements.
In this case, EPSS
are closer to the notion of computerized help desks in which the sole purpose of the computer is to assist someone in performing some task, such as the diagnosis of a machine failure or the evaluation of an individual's personal credit.
Consider HP Call Agent, a help desk support system that Hewlett-Packard submitted to the 2001 EPSS
The Developmental Study on EPSS
for Professional Skills Improvement.
LVPWd, LVPWs, IVSd, IVSs and EPSS
that were also significantly different (P<0.
Data were collected from two sets of in-depth, semi-structured interviews with three teachers (n=3), one focus group with two teachers in-2), and the district's EPSS
for SY 2011-2012.
In this regard, using an EPSS
in the role of the facilitator of an ethical decision-making process can be an effective and easy way to reach logical solutions to ethical issues.
Speaking at the Central Banks Payment Systems Experts' meeting which opened on Wednesday in Dakar, Senegal, on the establishment of the ECOWAS Payment and Settlement System (EPSS
), the Commissioner for Industry and Private Sector Promotion Kalilou Traore, said the EPSS
programme was one of the road map activities for the realisation of the ECOWAS single currency, and was in line with steps already taken by some Regional Economic Communities (RECs) across the African Continent.
