This paper is based on a project which was funded under the EU DELTA r
esearch initiative with participating partners from the UM, The Nether
lands, Germany and Ireland. It describes the purpose, design and devel
opment of a knowledge-based computer system that addresses Training Ne
eds Analysis (TNA). The consortium of industrialists and academics des
igned and built an innovative software tool which gives accurate and c
onsistent advice regarding training requirements for an organisation's
personnel. TO create this tool, knowledge engineers methodically inte
rviewed and elicited knowledge from several experts in the domain of h
uman training and development. The final system entailed representing
the underlying knowledge structures and concepts of the training needs
analysis process. The application was constructed to represent traini
ng needs analysis decision making and the system and interface were bu
ilt using Visual Baste. The final application has been critically eval
uated by end-users at several test sites across Europe.
