Abstract

In this paper, we describe a research project in which Core-Task Analysis (CTA) is used to elicit functional requirements for an adaptive user interface of a batch process control system. The process under study is a continuous steel casting process the end products of which are steel slabs of varying size and quality. The paper is aimed to be methodological describing how technological requirements can be formulated with a work analysis method. Description of the prototype implementation shows how practical constraints and tools available form the solution. In the study it was find out that CTA works as work analysis method and with it, it is possible to identify interface content related requirements for new tools.
