Lean communication-centered design: A lightweight design process

Abstract

Lean Communication-Centered Design (LeanCCD) is a humancomputer interaction (HCI) design process, which consists of conducting a workshop, detailing user goals, combining interaction models with paper sketches, and testing them with users, supported by guides and templates. This study adapted the Communication-Centered Design (CCD) and the eXtreme Communication- Centered Design (eXCeeD), other communication-centered design processes grounded in Semiotic Engineering (SemEng). SemEng defines user-system interaction as a computer-mediated communication process between designers and users. Approaches and processes based on SemEng are not used to directly yield the answer to a problem, but to increase the problem-solver’s understanding of the problem itself and the implication that understanding brings about. Process evaluation in a case study, in the industry, proved itself difficult, both in carrying out LeanCCD activities and in the correct application of some techniques and concepts. However, unlike eXCeeD, we were able to observe a systematic use of support questions that contributed to the designers’ reflection, aided by the proposed templates and guides.
