One Work Analysis, Two Domains: A Display Information Requirements Case Study

Abstract

Work domain analyses can be time consuming, requiring extensive interviews, documentation review, and observations, among other techniques. Given the time and resources required, we examine how to generalize a work domain analysis technique, namely the hybrid Cognitive Task Analysis (hCTA) method across two domains in order to generate a common set of display information requirements. The two domains of interest are field workers troubleshooting low voltage distribution networks and telecommunication problems. Results show that there is a high degree of similarity between the two domains due to their service call nature, particularly in tasking and decision-making. While the primary differences were due to communication protocols and equipment requirements, the basic overall mission goals, functions, phases of operation, decision processes, and situation requirements were very similar. A final design for both domains is proposed based on the joint requirements.

“…A. Miller & Vicente, 2001) with limited definition, consistency, and specificity. Furthermore, while various methods have attempted to demonstrate and link CSE requirements to specific CSE model components (Cattermole, Horberry, & Hassall, 2016;Cummings, 2004;Cummings, Tappan, & Mikkelsen, 2012;Lintern, 2006;Nehme et al, 2006), the extent to which these studies emphasize the actual requirements derivation process and situate their development within traditional SE processes is limited. Although examples are deemed valuable within the CSE community for their specific domain application, if they cannot be translated to the SE community of system developers, customers and other engineers, CSE insight and influence will remain limited (McIlroy & Stanton, 2012).…”
