    Incomplete software requirements and assumptions made by software engineers
    (IEEE, 2009) Albayrak, Özlem; Kurtoǧlu, Hülya; Biçakçi, M.
    Many software engineers make implicit assumptions when working with incomplete software requirements. To study assumptions made by software engineers while converting incomplete requirements to software design or to implementation phase deliverables, we conducted an experiment with 251 software engineers from eight companies. The results of this empirical study showed that how software engineers responded (using source code, pseudo code, or prototype) to an incomplete requirement significantly impacted the number of explicit assumptions they made. We studied relationships between the number of explicit assumptions and the engineers' experience and educational backgrounds. On average, non-computer-background engineers made more explicit assumptions than computerbackground graduates. We found a significant relationship between the engineers' experience and the number of explicit assumptions made. We discuss the results and their implications. © 2009 IEEE.

    Modelling detailed information flows in building design with the parameter-based design structure matrix
    (Elsevier, 2006-01) Tasli Pektas, S.; Pultar M.
    The Architecture/Engineering/Construction (AEC) industry is one of the multidisciplinary domains in which collaboration among related parties is of utmost importance. Despite the intense flow of information between design professionals, there is a lack of research to better understand and manipulate these flows. Most of the current process modelling tools in the AEC industry do not enable analyses of iterative information cycles. Moreover, these tools represent the process at high levels, thus, they are inadequate for multi-parameter problems like building design. With a view to alleviate these problems, this paper introduces the use of parameter-based design structure matrix as a process modelling and system analysis tool for building design. The method reveals insights into the process structure, optimum sequence of parameter decisions, iterative cycles and concurrency in the process. The application of the method is demonstrated through a case study on suspended ceiling design in a real-life project.
