To design an easy-to-use interface, pay attention to what users do, not what they say. Self-reported claims are unreliable, as are user speculations about future behavior.

Lee, Kyoung Jun, Chang, Yong Sik, Choi, Hyung Rim, Kim, Hyun Soo, Park, Young Jae and Park, Byung Joo (2004): A Time-Bound Framework for Negotiation and Decision Making of Virtual Manufacturing Enterprise. In Journal of Organizational Computing and Electronic Commerce, 14 (1) pp. 27-41.

Virtual manufacturing has 2 characteristics as an agent-based electronic commerce environment: dynamic nature of resource status and variety of agents' decision-making (i.e., scheduling) model. To reflect the characteristics, a relevant negotiation protocol should be designed and an appropriate decision-making model should be developed. In this article, from the perspective of a sales agent that is a middle man between customers and manufacturers in a virtual manufacturing environment, we provide a case study that suggests a time-bound framework for external negotiation between sales agents and customer agents, and internal cooperation between sales agents and manufacturing agents. We assume a job shop as the production model of a virtual manufacturing enterprise and formulate the optimal order selection problem with mixed integer programming, but its computation time is not acceptable for real-world problems. For this time-constrained decision making, we develop a genetic algorithm as an anytime problem-solving method for the scheduling of the production model, which shows a reasonable computation time for real-world cases and good incremental problem-solving capability.
