title	A digital Procedure of Building Construction: A practical project
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	In earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.

title	Psyberdesign: Designing the Cognitive Spaces of Virtual Environments
source	Digital Design Studios: Do Computers Make a Difference? [ACADIA Conference Proceedings / ISBN 1-880250-07-1] Québec City (Canada) October 22-25, 1998, pp. 276-288

summary	Increasingly, we find ourselves spending more time on a daily basis engaged in a variety of virtual environments, ranging from those discovered when using the stand-alone computer, to more complex distributed networks such as the World Wide Web. Virtual environments are not restricted to the popular and hyped notion of immersive Virtual Reality systems, though, in immersion, such systems provide a dimension of experience sorely lacking in most human-computer interfaces. The design of a diverse range of virtual environments, from textual through to three dimensional, would seem to require insight from those who habitually create immersive experiences, whether real or virtual. The former include architects, the latter the authors of computer games. Virtual environments such as the Internet, and the World Wide Web in particular, are becoming increasingly confusing to navigate. Exploratory behaviour in these environments requires extensive cognitive effort, and often results in disorientation and a sense of anxiety. This paper attempts to address issues of cognitive mapping in virtual environment design, and the exciting role that architects should occupy in the creation of better virtual environments. A virtual environment tool, called WOMBAT, has been developed to discover more about the relationship between real environment and virtual environment navigation and cognitive mapping, and consequently the degree to which concepts and theories from real environment design and cognitive mapping research can be translated to the virtual environment domain. Both a natural environment and an information environment are being investigated using WOMBAT, with the primary interest being the cognitive mapping and wayfinding activities that are exhibited during exploration.

title	A Virtual Studio Environment for Design Integration
source	Advances in Engineering Software, vol 29, No 10, 787-800
summary	In this paper the authors attempt to stress the social dimension of design and the role of explicit support for human-level interaction during design systems integration. A human-centred approach is proposed by taking design integration as the collaborative use of design artefacts, and a virtual studio environment (VSE) framework is presented as an integration vehicle to link the social and technical dimensions. A VSE consists of two subsystems: the VSE base system and the domain resources. While common generic facilities for human-human interaction are embedded within the VSE base system, the domain-specific resources are loosely coupled into VSE via resource agents. A VSE prototype for the domain of building design is described, and a demonstration of the use of the VSE prototype is presented. This is then followed by some discussion on related research and further work.

title	Computational Specification of Building Requirements in theEarly Stages of Design
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	We have been exploring computational techniques to help building designers to specify design requirements during the early stages of design. In the past, little has been accomplished in this area either in terms of innovative computational technologies or the improvement of design performance.The prospect of improving design productivity and creating a seamless process between requirements specification and formal design are our primary motivations. This research has been conducted as partof a larger project entitled SEED (Software Environment to Support Early Phases in Building Design). SEED features an open-ended modular architecture, where each module provides support for a design activity that takes place in early design stages. Each module is supported by a database to store and retrieve information, as well as a user interface to support the interaction with designers. The module described in this paper, SEED-Pro (the architectural programming module of SEED), is a workingprototype for building design requirements specification. It can be used by other modules in SEED or by design systems in other domains, such as mechanical engineering, civil engineering, industrial designand electrical engineering. Our approach to SEED-Pro is divided into two phases: core, and support functionalities. The core functionalities operate in an interactive mode relying on a case-based approach to retrieve and adapt complex specification records to the problem at hand. The supportfunctionalities include the case-base, the data-base, and the standards processing environment for building specification tasks. Our findings indicate that SEED-Pro: (1) is a tool that structures the unstructured domain of design requirements; (2) enables the integration of design requirements with the rest of the design process, (3) leads to the creation of complex case-bases and (4) enables the observation of their performance in the context of real world design problems.

title	Extending spatial DSS with spatial choice models of multipurpose shopping trip behaviour
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	Spatial choice or interaction models have been widely used in spatial DSS or customised GIS for analysing the impacts of retail location plans. The models typically used, however, do not account for spatial agglomeration effects on spatial choice behaviour. This study develops a model system for analysing the impacts of retail plans based on a choice model of multipurpose behaviour developed in earlier work. The model system is implemented in the spatial DSS called Location Planner. An empirical study demonstrates the empirical estimation and use of the model for analysing the impacts of an expansion of floor space in the major shopping centre of a middle-sized city in The Netherlands. The results indicate that agglomeration effects as predicted by the model can have substantial impacts on the performance of retail systems. Therefore, it is argued that when incorporated in a spatial DSS, the more complex models have the potential to improve the use of these systems for impact analysis.

title	Collaborative Architectural Design as a reflective Conversation: an agent facilitated system to support collaborative conceptual design
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	In this paper, definitions of collaborative design are discussed and understood in terms of a designer’s cognitive collaborations to explore his/her experiential memory for remote idea associations. Based on Schon’s reflective practice theory, Valkenburg and Dorst’s (1998) description of collaborative team designing is adopted as a model for a proposed design conversation system. The design conversation system is aimed at triggering the experiential memory of the designer by associating significant ideas from different design domains to provide different perspectives of a design situation. The paper describes a proposed framework for the design conversation system incorporating computational agents in a blackboard architecture environment.

title	Classification of Precedents - A Hybrid Approach to Indexing and Retrieving Design Cases in SEED (a Software Environment for the Early Phases of Building Design)
source	CAADRIA ‘98 [Proceedings of The Third Conference on Computer Aided Architectural Design Research in Asia / ISBN 4-907662-009] Osaka (Japan) 22-24 April 1998, pp. 435-444
doi	https://doi.org/10.52842/conf.caadria.1998.435
summary	An efficient indexing of past solutions is crucial to case-based design (CBD) systems performing complex retrieval on large case-bases. This paper suggests a hybrid approach to the indexing and retrieval of design precedents. The suggested approach accounts for the issues of classification manifested in architectural discussions on type and CBD literature. The indexing scheme integrates description-logic based representation for classification and an object-based representation for precedents. The hybrid scheme constitutes a basis for the implementation of a generic case indexing and retrieval mechanism for SEED.

title	Changing trends and approaches in human and computer modelling for social housing policies
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	The paper discusses conceptual issues, goals and preliminary results of an on-going research which aims at building a Decision Support System for public housing environmental oriented maintenance and management in a city in Southern Italy, Bari. Traditional post-war Italian housing policies are compared with more recent approaches in the field, pointing out the change from quantitative, aggregated, more simple building problems and relatedapproaches to qualitative, differentiated, complex ones integrating social, economic and environmental dimensions with the aim of regenerating deteriorated residential areas. The paper claims for the need shift, both in the human and computer areas, from traditional quantitative models to new approaches able to manage also qualitative variables, temporal dynamics, emergencies, and intentionality, since they appear key aspects of the real world to be modelled. The housing estate of Bari and its needs of maintenance and management are examined, eliciting essential related knowledge using the interview technique. The clear orientation towards sustainable policies for urban regeneration, at a local, national, and Community level, is also considered. The innovative and collaborative nature of such policies and the attention to be paid to the social aspects ofthe problem require a complex DSS, integrating various kind of hypertexts, information systems and case-based fuzzy expert systems, whose main aims, functions, software and general organisation are outlined in the paper.

source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	An analysis is made of the relation between the conceptualand paradigmatic level of GIS technologies and the new forms of plan, whichmake environment the center of attention. The intention is to study newcriteria for zoning able to give contextual representations of theterritorial, environmental and landscape aspects of the geographical space,and also to study new legislative principles, able to establish integratedrules for theprojecting of soil uses, the safeguarding and recovery ofenvironmental systems and the tutelage and boosting of the landscape. The experimentation of GIS (Geographical Information System)technologies aims at the construction of systems helping to make decisionsfor the control of the environmental and landscape aspects of theterritory. An analysis is made of the ways in which there are formulated thedescriptions of the various aspects of the environment: the conceptsthrough which knowledge is expressed, the languages used forrepresentations, the cognitive models adopted. GIS technologies have made it possible to represent in an explicitmanner the paradigms underlying the various models of knowledge.Specifically, the following cognitive models have been developed:- ecological models of nature- ecological models of human settlement- ecological models of inhabitants’ mental perceptions

title	Delegation and Circumvention: Two Faces of Efficiency
source	Proceedings of CHI'98 (1998), 273-280
summary	Throughout history, inefficient methods to use devices have been replaced by more efficient ones. This shift typically occurs when users discover how to &legate work to the powers of a tool, and to circumvent its liiitations. Strategies of delegation and circumvention, therefore, appear to be the core of efficient use. To show how this approach can expiain the relationship between tools and strategies in complex computer systems, we describe five ways to perform a real-world drawing task with current as well as 5.rture tools. We then present five corresponding GOMS models that demonstrate the value of efficient strategies when compared to the observed behavior of a professional CAD user. We conclude by presenting a generalized framework to characterize efficient strategies and discuss its relevance to design and training.

title	Grammars and Pedagogy - Towards new Media Art and Design Education Strategies
source	CAADRIA ‘98 [Proceedings of The Third Conference on Computer Aided Architectural Design Research in Asia / ISBN 4-907662-009] Osaka (Japan) 22-24 April 1998, pp. 385-394
doi	https://doi.org/10.52842/conf.caadria.1998.385
summary	The impact of computational grammatical design on pedagogy has received little attention in art education due to the dominant modes of traditional approaches to art and design education. This paper explores the pedagogical implications of grammatical strategies using computers for judgements of design within an art educational setting. Grammatical strategies are studied for their effect on the judgements of novice artists in a new media educational context. It is argued that concepts of grammar and views of contingency are used in a variety of senses in the conception and form making of artists; that finding methods for discussing and utilising complex visual information is aided by grammatical formalisation; that these strategies are evidently effective at both early and mature stages of the realisation of a project. The research explores the relation between computer and art on three levels in which grammar is used: as a sense of grammar, as a computational paradigm and as a description of a kind of computer program. Grammatical formalism is apparent in two dimensional linear and non-linear animations using Photoshop, Premiere and Director, and in solid modelling programs such as Extreme 3D, Form Z, Strata Studio Pro, 3D Studio Max and SoftImage. Web site construction also impacts on the judgements of 2D and 3D design. Computational grammatical programs generate forms that reflect alternative understandings of art and design. Art practise is defined in terms of developing consistent and appropriate design language for the contingency at hand. Form making using grammatical tools, both recursive and array types, is discussed in terms of their applicability and educative value. Reference is made to formal qualities for critique and strategic capability of alternative pedagogy for generation of forms. Examples provided show how simple rule sets develop into complex derivational sequences that challenge traditional strategies for computer imaging. The paper demonstrates the value of a sense of grammars for novice art and design practitioners by using first hand examples of experimental work at the South Australian School of Art, University of South Australia. For novice artists and designers, grammars in conjunction with reflective practice is offered as a useful mind set that supports an interest in actively defining a new kind of art. Illustrations provided show the utility of a contingent sense of grammar for pedagogy and highlights the significant role of grammar in pedagogy.

title	Representation, Realism and Computer Generated Architectural Animation
source	Cyber-Real Design [Conference Proceedings / ISBN 83-905377-2-9] Bialystock (Poland), 23-25 April 1998, pp. 241-249
summary	This paper documents a simple architectural form which, but for computer generated animation, has no ready alternative explanatory process for its complex generation. The subject is a column in the nave of the Sagrada Familia Church in Barcelona conceived by Gaudí at the beginning of this century without the contemporary opportunities for animated design exploration. The column is based on a set of counter-rotating mutually interfering profiles. As the column gains height, the profiles increase in interference with each other resulting in an increasingly fluted cross section, a tendency towards the Doric Order. For most, however, there is no easy access to a plausible explanation of the inherent rationale for the column. Animating the generation of the column reveals a unique and concealed sublimation of natural patterns of growth. Animation aids an understanding of the effect of the fourth dimension on design itself by releasing a meaning of time from an otherwise inanimate object. Here animation is used to decipher one aspect of the mystery of Gaudí's design while strengthening another: the source and conceptual power of Gaudí to anticipate this phenomenon. Rather than trivialising this design mystery, the explanatory role of the animation enriches comprehension of the formal concept of mutation through displacement or an evolutionary design paradigm. The paper discuss the implications of this ability to show transition, translation and dislocation without delving too deeply into how the animation was made, nor indeed the subject which, after all, requires animation to fully represent its less tangible qualities.

source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	To emphasise the reusing of the local identities and cultural effects on contemporary designs, this paper is believed to have an important role for architects and for further designs. In this paper design theories in 1000's BC from Priene is held. The theories in urban and architectural design took place. From the intersection point of Ancient Greek and Western Anatolia, a city named "Priene" is chosen as a point of view because of its speciallocation on the Aegean Sea Coasts; Asia Minor and its design principles on urban and housing scale which were used during 1000's and are still common. Also, in this paper, an analysis is done on urban and housing scale. The analysis has two main parts. In the first part, the important buildings in Priene and their settlement decisions take part. And in the second part, the houses of Priene are explained. The general outputs of the study can be put under two titles: urbanism and architecture. In terms of urbanism, those features of a city image reflecting onto today’s world have been examined and the city of Priene has been analysed in the content of Lynch’s elements ensuring formation of a city image. In terms of architecture, results obtained have been separately examined in the content of today’s architecture as public buildings reflecting unique characteristics of Hellenistic architecture and as settlements. In short, the result that it is wished to reach in terms of city scale of the city of Priene in this study isthe expression of the essence of the historical heritage using a modern language to ensure historical continuity.

title	Cognitive accessibility to information on the Web: insights from a system for teaching and learning Architecture through the Net
source	AA VV, Towards an Accesible Web, Proceedings of the IV ERCIM Workshop “User Interfaces for All”, Långholmen-Stockholm
summary	The question of accessibility to the Web takes on a special meaning in educational settings where access to information requires cognitive elaboration of the page contents. It is, therefore, a matter of "cognitive access" to the Web. The main efforts of the designers of Web Based Instruction (WBI) environments to encourage cognitive access are usually aimed at the organisation and presentation of Web documents and at specific cues which can improve the user's interaction, orientation and navigation through the pages. However, it is possible to improve this high-level access to the information by supporting study activities through specific "Working tools" which can be implemented in the Web environment. In this paper we report on the design solutions we have adopted to provide cognitive access to a WBI environment for university students studying Architecture and Town Planning. In particular, we introduce "Working tools" that can be used to support flexible and effective study activities. The adopted design solutions provide different classes of users (not only students) with different access facilities. Finally, it should be noted that the methodologies of the design of WBI systems should deal with this kind of high level access and support it through specific solutions at interface and implementation levels.

title	Evaluating Office Buildings with MOLCA(Model for Office Life Cycle Assessment)
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	MOLCA (Model for Office Life Cycle Assessment) is a project that aims to develop a tool that enables designers and builders to evaluate the environmental impact of their designs (of office buildings) from a environmental point of view. The model used is based on guidelinesgiven by ISO 14000, using the so-called Life Cycle Assessment (LCA) method. The MOLCA project started in 1997 and will be finished in 2001 resulting in the aforementioned tool. MOLCA is a module within broader research conducted at the Eindhoven University of Technology aiming to reduce design risks to a minimum in the early design stages.Since the MOLCA project started two major case-studies have been carried out. One into the difference in environmental load caused by using concrete and steel roof systems respectively and the role of recycling. The second study focused on biases in LCA data and how to handle them. For the simulations a computer-model named SimaPro was used, using the world-wide accepted method developed by CML (Centre for the Environment, Leiden, the Netherlands). With this model different life-cycle scenarios were studied and evaluated. Based on those two case studies and a third one into an office area, a first model has been developed.Bottle-neck in this field of study is estimating average recycling and re-use percentages of the total flow of material waste in the building sector and collecting reliable process data. Another problem within LCA studies is estimating the reliability of the input data and modelling uncertainties. All these topics will be subject of further analysis.

title	Computer Graphics and Architecture: State of the Art and Outlook for the Future
source	Computer Graphics, Vol 32, No 1, Feb 1998. pp. 45-48
summary	During the three decades since Ivan Sutherland introduced the Sketchpad system, there has been an outpouring of computer graphics systems for use in architecture. In response to this development, most of the major architectural firms around the world have embraced the idea that computer literacy is mandatory for success. We would argue, however, that most of these recent developments have failed to tap the potential of the computer as a design tool. Instead, computers have been relegated largely to the status of drafting instruments, so that the "D" in CAD stands for drafting rather than design. It is important that future architectural design systems consider design as a continuous process rather than an eventual outcome.The advent of computer graphics technology has had an impact on the architectural profession. Computer graphics has revolutionized the drafting process, enabling the rapid entry and modification of designs. In addition, modeling and rendering systems have proven to be invaluable aids in the visualization process, allowing designers to walk through their designs with photorealistic imagery. Computer graphics systems have also demonstrated utility for capturing engineering information, greatly simplifying the analysis and construction of proposed designs. However, it is important to consider that all of these tasks occur near the conclusion of a larger design process. In fact, most of the artistic and intellectual challenges of an architectural design have already been resolved by the time the designer sits down in front of a computer. In seeking insight into the design process, it is generally of little use to revisit the various computer archives and backups. Instead, it is best to explore the reams of sketches and crude balsa models that fill the trash cans of any architectural studio.In architecture, as in most other fields, the initial success of computerization has been in areas where it frees humans from tedious and mundane tasks. This includes the redrawing of floor plans after minor modifications, the generation of largely redundant, yet subtly different engineering drawings and the generation of perspective renderings.We believe that there is a largely untapped potential for computer graphics as a tool in the earlier phases of the design process. In this essay, we argue that computer graphics might play a larger role via applications that aid and amplify the creative process.

summary	Conceptual design using conventional 3D CAD systems is a controversial issue among industrial designers. Although one can produce complex, accurate, finished 3D models using these CAD systems, it is still difficult to use them during early, creative product design. In this paper, a method is described that allows the design of protrusions and depressions in sculptured surfaces in a flexible and interactive manner. Through interviews with industrial designers, the basic requirements for support of such functionality during conceptual design have been formulated. An implemented method based upon these requirements has been extensively evaluated by industrial designers, and these evaluations show that industrial designers find this functionality extremely useful during conceptual shape design.

summary	Sketching with pencil and paper is reminiscent of the varied, rich, and loosely defined formal processes associated with conceptual design. Architects actively engage such creative paradigms in their exploration and development of conceptual design solutions. The Grid Sketcher, as a conceptual sketching tool, presents one possible computer implementation for enhancing and supporting these processes. It effectively demonstrates the facility with which current technology and the computing environment can enhance and simulate sketching intents and expectations. One pervasive and troubling undercurrent, however, is the conceptual barrier between the variable processes of human thought and those indigenous to computing. Typically with respect to design, the position taken is that the two are virtually void of any fundamental commonality. A designer’s thoughts are intuitive, at times irrational, and rarely follow consistently identifiable patterns. Conversely, computing requires predictability in just these endeavors. Computing is strictly an algorithmic process while thought is not always so predictable. Given these dichotomous relationships, the computing environment, as commonly defined, cannot reasonably expect to mimic the typically human domain of creative design. In this context, this thesis accentuates the computer’s role as a form generator as opposed to a form evaluator. The computer, under the influence of certain contextual parameters can, however, provide the designer with a rich and elegant set of forms that respond through algorithmics to the designer’s creative intents. The software presented in this thesis is written in AutoLISP and exploits AutoCAD’s capacious 3D environment. Designs and productions respond to a bounded framework where user selected parametric variables of size, scale, proportion, and proximity, all which reflect contextual issues, determine the characteristics of a unit form. Designer selected growth algorithms then arbitrate the spatial relationships between the unit forms and their propagation through the developing design. While the Sketcher implements only the GRID as an organizational discipline, many other paradigms are possible. Within this grid structure a robust set of editing features, supported by the computer’s inherent speed, allows the designer to analyze successive productions while refining ever more complex solutions. Through creative manipulation of these algorithmic structures ideas eventually coalesce to formalize images that represent a given design problem’s solution set.

summary	The Design Process - inherent conflicts? It is frequently stated that the activity of design is an iterative one; ie that it is a process whereby ideas are refined through constant change and development; if one also considers that designing is also very difficult: Hartwell and Holland (1) describe design "as an activity which attempts to reach an effective compromise between conflicting, complex and often apparently irreconcilable criteria"; then the key question arises: how can there be an effective interface between the obviously creative (generative?) elements of the design process and the (often) very functional / technical requirements of a typical design outcome.
