This work describes the research conducted in the quest for designing better software for discrete-event system (DES) control. The think-aloud data from an exploratory observational study of solving DES control problems, together with other relevant research, led to the proposal of a novel approach to DES problem solving called the template design methodology. This methodology does not require the introduction of new control theory; it is rather an reinterpretation of the existing modelling framework. It provides a high-level overview of a DES design, and facilitates the use of template models. Software supporting this methodology was implemented as an extension to existing DES software. The methodology and the implementation were subsequently evaluated using 12 subjects. Significant improvements in the speed of problem solving as well as positive evaluations by the subjects were observed. The usability data do not show any drawbacks to applying the methodology.
