Gallemore Submitted to the Department of Architecture on May 8, 1998 in partial fulfillment of the requirements for the degree of Master of Science in Architecture Studies Abstract Our model of work is shaped by the places we choose to work and the tools we choose to work with. As we introduce new technologies and build new environments our model is changing. Today's virtual workplaces are grounded in models of work that have been reformed from our experiences using current technology in physical workspace. However we are discovering opportunities and possibilities for work in collaborative, virtual environments that question physical models. Emerging patterns of distributed collaboration in persistent virtual environments are changing the way we work in time and space, recasting our notion of workplace. Virtual workplaces are interpreted and experienced through metaphors that describe a space of potential for work occurrences. Through the lens of metaphors, this research focuses on breakdowns between collaborative work and the environment in which work occurs. If what we understand and predict is based on what we already know, then by examining the breakdowns between design and use of collaborative environments we can illuminate the space of possibilities for collaborative work. Thesis Supervisor William L. Porter Norman B. and Muriel Leventhal Professor of Architecture and Planning Acknowledgments This research is a collaboration between MITRE Corporation of Bedford, Massachusetts and MIT Space Organization Research Group (SPORG) in Design Technology. The common ground stems from MITRE's research and development of Collaborative Virtual Workspace (CVW) and MIT-SPORG's design research in physical and virtual collaborative work settings and tools.

Does someone want your attention or is someone just passing along a message? You screen your calls, you look through the peep hole, or filter incoming messages. Depending on who it is or what it is about, you will decide whether or not to engage an immediate response. You are in control. The door opens. A co-worker stops by your desk. A message instantly appears on your desktop. It doesn't matter who it is or what it is about, you have to respond. Not only is it easier to reach our colleagues, it is easier for them to reach us. When we work together we adapt conventions for how we interact in space and time. When someone answers the phone we expect a responding 'hello', when an office door is open we assume availability. When we work in different places and at different times we adapt our behavior to fit the context. If there are no doors we may use signage or body language. Over time the patterns of behavior become convention, through mutual acceptance and reinforcement. The patterns in which we interact with one another and with our context, form the basis of our model' of work practice. If our goal is to improve the way we work, our purpose for modeling is to describe and access key features and their relationships so that they can be finessed. By constructing models we can make hypotheses and evaluate alternative theories. Models do not replicate either the real or imagined original, rather they are incomplete, and are inevitably susceptible to distortion. If our model is too detailed, the features become increasingly cumbersome to access and manipulate. If too obscure, the features and relationships become increasingly difficult to identify. The way in which we represent and describe our models are then subject to rules of interpretation for accuracy. By observation and engagement in work, we are continually validating and reshaping our models of work practice (Black 1962) to test out new processes and work strategies. Our constructions and interpretations are asymmetrical and are due individual differences and contextual differences. Individual differences are due to professional orientation, personal style, background experience as well as emotional state or career position. Contextual differences are due to available resources, indexed references and presence of others. When we construct shared models of work practice for collaborative work, we need not reconcile the differences, we need only to provide a structure that can accommodate individual and contextual differences. The key to understanding, is the structural consistency in which assertions made in our model can be related to what we are modeling. If our purpose is to improve the work practice then the value of our model will be in revealing relationships and features that we may have otherwise overlooked. The challenge of interpretation then, is that of dueling inquires: what does the model reveal that is new, and what does the model hide in its incompleteness. If we return, to the previous example, we can see that behavior is influenced by the tools and places in which we work, in this case the convenience of interaction. Eventually, as we become more familiar with our tools and our workplace, these patterns of behavior become internalized in our models of work practice. When we don't want to be disturbed we close the door. In this model of the workplace, the function of the door is to avoid unwelcome interaction, by providing privacy and maybe security. The door provides a way to control, or at least influence, interactions. When we move to an open office layout, without doors, we naturally feel the loss of privacy. If we apply our model of the door to the new context, we would look for solutions that meet our need for privacy. First, we would consider those properties of the door that provided Chapter One Modeling WorkPlaces privacy, such as enclosure and visual and acoustic separation. Next we might consider a 'do not disturb' sign. If all else fails we might resolve to relocate. What our model hides is that the door did not function without the mutually adapted convention for its use (in this case that a closed door implies 'do not disturb'). The promise of modeling work processes and work settings is to provide insight on existing practice, to explore alternatives for new ideas, and to generate inquiry into meaningful design. The challenge is to see beneath the surface, to reveal the hidden structures that influence the construction and interpretation of models that generate solutions and preclude others.
