Pilot implementations are field tests of properly engineered, yet unfinished, systems. In contrast to lab tests, the users in a pilot implementation use the system for performing real work. In contrast to full-scale implementations, the objective of a pilot implementation is to learn. The workshop on pilot implementation aims to (a) help mature this technique for evaluating human-work interaction designs during the process of their development and implementation, (b) collect case studies that analyze experiences with conducting and learning from pilot implementations, and (c) formulate a research agenda for future work on pilot implementations – addressing their strengths, limitations, conduct, impact, and so forth. The target audience for the workshop is researchers and practitioners working on topics related to work analysis, interaction design, system-organization fit, organizational implementation, benefits realization, and in-the-wild evaluation.
