Katzenstein, Gary and Lerch, F. Javier (2000): Beneath the surface of organizational processes: a social representation framework for business process redesign. In ACM Transactions on Information Systems, 18 (4) pp. 383-422
This paper raises the question, "What is an effective representation framework for organizational process design?" By combining our knowledge of existing process models with data from a field study, the paper develops criteria for an effective process representation. Using these criteria and the case study, the paper integrates the process redesign and information system literatures to develop a representation framework that captures a process' social context. The paper argues that this social context framework, which represents people's motivations, social relationships, and social constraints, gives redesigners a richer sense of the process and allows process redesigners to simultaneously change social and logistic systems. The paper demonstrates the framework and some of its benefits and limitations.

Fussell, Susan R., Kraut, Robert E., Lerch, F. Javier, Scherlis, William, McNally, Matthew M. and Cadiz, Jonathan J. (1998): Coordination, Overload and Team Performance: Effects of Team Communication Strategies. In: Poltrock, Steven and Grudin, Jonathan (eds.) Proceedings of the 1998 ACM conference on Computer supported cooperative work November 14 - 18, 1998, Seattle, Washington, United States. pp. 275-284. Available online
The goal of this paper is to identify the communication tactics that allow management teams to successfully coordinate without becoming overloaded, and to see whether successful coordination and freedom from overload independently influence team performance. We found that how much teams communicated, what they communicated about, and the technologies they used to communicate predicted coordination and overload. Team coordination but not overload predicted team success.

The main objective of this study is to uncover the differences in the programming behavior between methodology designers and methodology users. We conducted an experiment with methodology designers who have invented one of the major object-oriented methodologies and programmers who have used the methodology for their projects. Concurrent verbal protocols were analyzed based on a theoretical framework which views programming as search in four problem spaces: representation, rule, instance, and paradigm. In programming, the main problem spaces are the representation and the rule spaces, while the paradigm and instance spaces are the supporting spaces. The results of the experiment show that differences in the supporting space produced different search behavior in the main problem spaces, which in turn resulted in different final programs and performance.

This article investigates working-memory (WM) failure in phone-based interaction (PBI). We used a computational model of phone-based interaction (PBI USER) to generate predictions about the impact of three factors on WM failure: PBI features (i.e. menu structure), individual differences (i.e., WM capacity), and task characteristics (i.e., number of tasks). Our computational model stipulates that both the storage and the processing of information contribute to WM failure. In practical terms the model and the empirical results indicate that, contrary to guidelines for the design of phone-based interfaces, deep menu hierarchies (no more than three options per menu) do not reduce WM error rates in PBI. At a more theoretical level, the study shows that the use of a computational model in HCI research provides a systematic approach for explaining complex empirical results.

Kim, Jinwoo, Lerch, F. Javier and Simon, Herbert A. (1995): Internal Representation and Rule Development in Object-Oriented Design. In ACM Transactions on Computer-Human Interaction, 2 (4) pp. 357-390
This article proposes a cognitive framework describing the software development process in object-oriented design (OOD) as building internal representations and developing rules. Rule development (method construction) is performed in two problem spaces: a rule space and an instance space. Rules are generated, refined, and evaluated in the rule space by using three main cognitive operations: Infer, Derive, and Evoke. Cognitive activities in the instance space are called mental simulations and are used in conjunction with the Infer operation in the rule space. In an empirical study with college students, we induced different representations to the same problem by using problem isomorphs. Initially, subjects built a representation based on the problem description. As rule development proceeded, the initial internal representation and designed objects were refined, or changed if necessary, to correspond to knowledge gained during rule development. Differences in rule development processes among groups created final designs that are radically different in terms of their level of abstraction and potential reusability. The article concludes by discussing the implications of these results for object-oriented design.

Kim, Jinwoo and Lerch, F. Javier (1992): Towards a Model of Cognitive Process in Logical Design: Comparing Object-Oriented and Traditional Functional Decomposition Software Methodologies. In: Bauersfeld, Penny, Bennett, John and Lynch, Gene (eds.) Proceedings of the ACM CHI 92 Human Factors in Computing Systems Conference June 3-7, 1992, Monterey, California. pp. 489-498. Available online
This study aims at developing and empirically testing hypotheses about professional designers' cognitive activities when using object-oriented methodology (OOD) versus using traditional functional decomposition methodologies (TFD). Our preliminary results indicate that OOD may achieve substantial time savings over TFD in logical design. The verbal protocols from a pilot study show that OOD may achieve these time savings: 1) by simplifying rule induction processes used in functional decomposition; 2) by guiding designers on how to build more effective problem spaces; and 3) by allowing designers to run mental simulation more efficiently and more effectively.

Proceedings of the ACM CHI 89 Human Factors in Computing Systems Conference April 30 - June 4, 1989, Austin, Texas. pp. 121-126.
We use GOMS models to predict error rates and mental times for translating financial concepts into equations in two widely used interface representations. The first of these, common to spreadsheet packages, is characterized by non-mnemonic naming and absolute referencing of variables. The second, common to non-procedural command-driven software, is characterized by mnemonic naming conventions and relative referencing of variables. These predictions were tested in an experiment using experienced financial analysts. Although the interface that allows mnemonic and relative names (called keyword) takes longer overall, it produces seventy-five percent fewer simple errors and requires less mental effort. Given the overall serious cost of errors in financial models, we conclude that interfaces having the keyword representation are far superior.

Lerch, F. Javier and Prietula, Michael J. (1989): How Do We Trust Machine Advice?. In: Proceedings of the Third International Conference on Human-Computer Interaction 1989. pp. 410-419.
A study was conducted to investigate the effects of source pedigree of problem solving advice on self-reported measures of agreement with the advice and confidence in the source of the advice. Each subject in the study received the same advice from a different attributed source (an expert system, a human expert and a human novice) for ten problem solving trials. For each trial, subjects were presented with a business problem, a possible solution (the advice), and instructions "to rate the extent to which they agreed with the advice". Confidence ratings in the source were obtained from the subjects four times throughout the trials. The results show subjects had the same level of confidence in the expert system as in the human novice, but higher confidence in the human expert. Surprisingly subjects agreed less with the human expert in the first problem, but this difference disappeared after the first trial. The results also indicate that there are differences on how confidence and agreement judgements are made when the advice is received either from an expert system or a human.
