summary	This paper discusses the preliminary findings of an ongoing research project aimed at developing a technological, operational and strategic analysis of adopting BIM in AEC/FM (Architecture-Engineering-Construction/Facility Management) industry as a collaboration tool. Outcomes of the project will provide specifications and guidelines as well as establish industry standards for implementing BIM in practice. This research primarily focuses on BIM model servers as a collaboration platform, and hence the guidelines are aimed at enhancing collaboration capabilities. This paper reports on the findings from: (1) a critical review of latest BIM literature and commercial applications, and (2) workshops with focus groups on changing work-practice, role of technology, current perception and expectations of BIM. Layout for case studies being undertaken is presented. These findings provide a base to develop comprehensive software specifications and national guidelines for BIM with particular emphasis on BIM model servers as collaboration platforms.

summary	The design and realization of complex buildings requires multidisciplinary design collaboration from early on in the design process. The intensive use of digital design environments in this process demands new knowledge and skills from the involved players including integrating and managing digital design data, developing custom design tools, and utilizing visualization and rapid prototyping techniques. In order to prepare our students for these evolving practices we have developed a multidisciplinary collaborative design studio, named XXL, where student teams work in groups and each students claims a role: architectural design, structural design, digital design, construction and cladding design, and process management. In this paper, we describe the studio, discuss the contributions of the Digital Design Manager, and relate these contributions to design education and practice.

title	Rivalry between the collective use of IT tools and working methods of design teams Comparison of research outcomes
source	H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary	Nowadays a high variety of IT tools is available for communication purposes in design processes on individual and group level. Despite this, the exchange and sharing of design documents collectively in design and engineering teams might be limited mainly, due to habits, preferences, working methods and rivalry between the collective use of IT tools in such product development. Changes in habits and preferences for collective use of IT tools might be realized by training and management power. However, adoption of collectively to be used tools, like project websites, is depending heavenly on the attractiveness for users in daily work. Based on empirical research outcomes it is indicated that rivalry between collective used tools and differences in working methods of users might be main barriers for attractiveness of these tools in daily work. Applying a framework for analyzing and categorizing of the frequency of use of IT tools for team communication, the authors explain the appearance of rivalry between tools, limiting the effectiveness in daily work and not affecting team communication and performance. By comparison of working methods in different sectors authors explain the necessity of changes in working methods in design and engineering in the building & construction industry on organizational and inter-organizational level for successful adoption of collectively to be used IT tools in team communication.

title	Interactive Feasibility-based CAAD System for Infrastructure and Open Space Planning in Housing Project Design
source	CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 143-148
doi	https://doi.org/10.52842/conf.caadria.2008.143
summary	The decision support system developed in this research is aimed to the conceptual scheme of project focusing on infrastructure planning and open space design in the architectural context for housing project. Alternative design sets are provided within the limitations, and possibilities to be further evaluated appropriately. This system helps architects and developers to analyze relationships of physical environment, architectural requirements and the overall of project-related factors with real-time cost estimation. Factors for cost estimation derived from the beginning to the end of project will be manipulated simultaneously. Architects and developers can use this design simulation to address the physical data with real-time cost estimation, provide alternative results, and design evaluation for overall project’s feasibility. The software of our research is not just a tool for design & planning automation in feasibility analysis. It will be an interactive decision support system for both developers and planners aspects. The system was developed by SketchUp Ruby Application Programming Interface. The results will be presented into two ways. Firstly, 2D and 3D modeling will be used for interactive visualization in design and planning of the beginning process. Subsequently, numbers and additional factors in details will be used to show relationship between architectural environment and feasibility-based information to help architects and developers collaboratively analyze the land use planning and open space design for housing project. In evaluation process, the developed software is tested with the project preceding and the future project of Bangkok area under constraints and regulations of Building Control Act of Thailand. In conclusion, this system will make effectiveness in design process and management of the construction knowledge. The decision support systems should be designed to makes explicit use of both planning analysis aspect and knowledge-based decision making.

title	Evaluating VBE AND BIM-frameworkS A Cost Estimation Case Study and Reflections to Environmental Issues
source	CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 81-88
doi	https://doi.org/10.52842/conf.caadria.2008.081
summary	This paper describes and evaluates two recently emerged concepts, Virtual Building Environment VBE and Building Information Modelling BIM, fitting them into the context of contemporary design and construction. Both are elementary concepts in modern digitally “reinforced” design and construction. A case study of cost estimation is presented to illustrate how discipline related issues are currently managed within VBE and BIM. An environmental aspect is presented as a corresponding domain to evaluate the other use cases of building related information. Other similar domains to be evaluated perhaps in further case studies could be the functional user aspect, the project management aspect and the regulating aspect by the society and authorities. A hypothetical assumption is, that methods and technologies which are currently used within VBE and BIM, mainly by designers, can well support various data extractions from BIM-models, but they may not serve all construction process participants in the most beneficial way. Also wider scale building portfolios are requested as conceptual extensions to VBE and BIM. This study is based on ongoing PhD studies on building information modelling and environmental life cycle assessment.

summary	Environmental and residential destruction caused by urbanization and land development raises a serious issue. In addition, advanced technology has quickly changed the structure of cities, followed by revolutionary changes are growing faster these days and this requires us to turn our attention into developing a symbiotic eco-city, which will make it possible for further sustainable development. In this regard, it grows much more important to manage a flood of information from various intelligent devices and systems for environmental maintenance. The structure and meaning of modern info-oriented cities have changed their focus from tangible materials and resources, or energy into intangible information and knowledge. Now it has become the most important on how to manage and utilize a vast amount of information in order to strengthen the competitiveness and improve the life quality. This study finds methods for an effective city management and planning, or visualization of information for ecology-friendly education in order to provide a comfortable city life and develop a cleaner city, by efficiently managing information on several ecology protection areas and their sauces of pollution in the centre of a city. The goal is to help city managers or planners to be better aware of environmental information related to their work.

title	Visual-Physical Grammars
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	This paper introduces new visual-physical design grammars for the design and manufacture of building assembly systems that provide visually rich, culturally resonant design variations for housing. The building systems are intended to be tailored for particular cultures and communities by incorporating vernacular, decorative design into the assembly design. Two complementary areas of computational design research are brought together in this work: shape grammars and digital fabrication. The visual or graphic aspects of the research are explored through shape grammars. The physical design and manufacturing aspects are explored through advanced digital design and fabrication technologies and, in particular, build on recent work on mono-material assemblies with interlocking components that can be fabricated with CNC machines and assembled easily by hand on-site (Sass, 2007). This paper describes the initial, proof-of-concept stage of this work: the development of an automated, visual-physical grammar for an assembly system based on a vernacular language of Greek meander designs. A shape grammar for the two-dimensional Greek meander language (Knight, 1986) was translated into a three-dimensional assembly system. The components of the system are uniquely designed, concrete “meander bricks” (Figure 1). The components have integrated alignment features so that they can be easily fitted and locked together manually without binding materials. Components interlock horizontally to form courses, and courses interlock vertically in different ways to produce a visual variety of meander walls. The assembly components were prototyped at desktop scale with a layered manufacturing machine to test their appearance after assembly and their potential for design variations (Figure 2). Components were then evaluated as full-scale concrete objects for satisfaction of physical constraints related to concrete forming and component strength. The automated grammar (computer program) for this system generates assembly design variations with complete CAD/CAM data for fabrication of components formed from layered, CNC cut molds. Using the grammar, a full-scale mockup of a corner wall section was constructed to assess the structural, material, and aesthetic feasibility of the system, as well as ease of assembly. The results of this study demonstrate clearly the potentials for embedding visual properties in structural systems. They provide the foundations for further work on assembly systems for complete houses and other small-scale structures, and grammars to generate them. In the long-term, this research will lead to new solutions for economical, easily manufactured housing which is especially critical in developing countries and for post-disaster environments. These new housing solutions will not only provide shelter but will also support important cultural values through the integration of familiar visual design features. The use of inexpensive, portable digital design and fabrication technologies will allow local communities to be active, cooperative participants in the design and construction of their homes. Beyond the specific context of housing, visual-physical grammars have the potential to positively impact design and manufacture of designed artifacts at many scales, and in many domains, particularly for artifacts where visual aesthetics need to be considered jointly with physical or material requirements and design customization or variation is important.

title	Simulating and assessing prospective scenariosA comparative approach in urban planning
source	H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary	The first part of the paper is centred on the phenomena of urban growth, in order to set the rules for a sustainable scenario of urban development. Then we enter the core of the paper that is the comparison of models. For each of the three compared models, we describe its main theoretical characteristics, the chosen parameters, and the obtained results. In section 6, heterogeneity of the produced results is discussed, and we highlight the points of interest and the lacks of the three models. Here we show that results we obtained feed debates about urban growth management. Finally, concluding remarks at the end of the paper address the general topic of the evaluation of the quality of simulation results.

summary	This paper can be viewed as the continued development of a research project presented at last year’s eCAADe. The project focused on the potential and possibilities of cooperation among architects, investors with concrete building projects, and researchers at the university level working on generative design and parametric construction. After having spent several years of research on design techniques in a purely academic setting at the university we see, contrary to our fears, that reality and the integration of concrete factors such as budget, time management, etc. does not diminish but rather improves the quality of our work. This work is not primarily concerned with the development of a new architectural language but the intelligent use of modern computer technology based on digitized planning processes defined as ‘complex building design’. Designs developed in this manner can be distinguished by certain characteristics, the evaluation of which is a point critically discussed in the following paper.

title	Strategic Perspectives of the Use of Virtual Reality within the Building Industries of Four Countries.
source	International Journal of Architectural Engineering and Design Management
summary	This paper presents results from the first stage of an analysis of the use of virtual reality (VR) within the building industries of strategically selected countries, namely, China, Sweden, the UK and the US. The aims of the research are to assess VR usage and its benefits within the building industries of these countries and to identify perceived barriers to VR usage and ways of overcoming them. The countries selected offer a range of experience in the adoption of VR technologies and the paper provides an initial analysis of developments at an international level. Semi-structured interviews were conducted with senior professionals from each of six leading construction companies within each country. The findings included the rationale for the adoption of VR and the barriers to doing so, as well as some divergence between the respondents in their working definition of what visualization and, specifically, VR actually represents.

title	The Urban Decision RoomApplication and Evaluation of an Urban Management Instrument
source	H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary	The Urban Decision Room (UDR) should be placed in the tradition of urban design and planning discipline that is taught, and into which research is carried out, at the Faculty of Architecture at the Delft University of Technology. The UDR was developed at the faculty as one of the new design and planning methods with its own specific features. The UDR is specifically aimed at decision-making processes in the practice of urban planning, and particularly at complex urban area development projects. The background to the design enables the UDR to support planning decisions that are made at urban planning element level. The participants in the interactive UDR sessions are asked to provide concrete solutions for urban planning design problems (in terms of preferences for particular functions, number of plots, etc.) and to enter them in a simulation model. A computer network is then used to calculate the common solution space of all the proposals, which is then projected onto a central screen. This outcome generally provides the basis for further discussions and negotiations, after which another round as described above can be held. The paper first focuses on the background and the main features of the UDR system. Secondly, the decision-making issue and a description of a specific Urban Decision Room model, the UDR Heijsehaven will be explained. Thirdly the structure of, and the experiences from, the experimental sessions with the Urban Decision Room Heijsehaven are described. After that the results of the evaluation of the UDR system by participants is presented and finally the follow-up assignment for the UDR system is carried out.

summary	The digital tools are most convenient technologies to realize distributed collaborative design environment on the web. A lot of practical design systems have been already developed with researches in the world. On these systems, the digital bulletin board and web-map technologies are generally used to support for group-discussing and exchanging design proposals via the web. But some of them are only possible to store design materials apart on the web and the peculiar interface is not well-optimized for architectural design activities. In this paper, we discuss to develop the collaborative design system simulated of our practical group-work methods. The APEX/VPB & MAP will realize the easy information management with interactive digital bulletin board and map-based interface. Finally, we will report the results of our experimental design studio using with APEX/VPB & MAP.

summary	Flexible mass customization of buildings is still in its infancy. Current systems for the automated support of owner-driven configuration management are limited with regard to the degree of freedom they offer to end-users. In this paper we present and discuss a constraint definition and verification system that allows the architect to specify boundary conditions within which the client can vary the design. The required constraint grammar is presented and applied to a real-world building code. A 2D floor plan prototype is tested to reveal the methodological and technical issues to be solved to make a step forward.

title	Digital Fabrication Production System Theory: Towards an Integrated Environment for Design and Production of Assemblies
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	A Digital Fabrication Production System (DFPS) is a concept describing a set of processes, tools, and resources that will be able to produce an artifact according to a design, fast, cheap, and easy, independently of location. A DFPS project is a complex assembly of custom parts that is delivered by a network of fabrication and assembly processes. This network is called the value chain. The workflow concept of a DFPS is the following: begin design process with a custom geometric form; decompose it into constructible parts; send the part files for fabrication to various locations; transport all parts at the construction site at the right time; finally, assemble the final artifact. Conceptually it means that based on a well structured value chain we could build anything we want, at anyplace, at controllable cost and quality. The goals of a DFPS are the following: custom shapes, controllable lead time, controllable quality, controllable cost, easiness of fabrication, and easiness of assembly. Simply stated this means to build any form, anywhere, accurately, cheap, fast, and easy. Unfortunately, the reality with current Digital Fabrication (DF) projects is rather disappointing: They take more time than what was planned, they get more expensive than what was expected, they involve great risk and uncertainty, and finally they are too complex to plan, understand, and manage. Moreover, most of these problems are discovered during production when it is already late for correction. However, there is currently no systematic approach to evaluate difficulty of production of DF projects in Architecture. Most of current risk assessment methods are based on experience gathered from previous similar cases. But it is the premise of mass customization that projects can be radically different. Assembly incompatibilities are currently addressed by building physical mockups. But physical mockups cause a significant loss in both time and cost. All these problems suggest that an introduction of a DFPS for mass customization in architecture needs first an integrated theory of assembly and management control. Evaluating feasibility of a DF project has two main problems: first, how to evaluate assemblability of the design; second, how to evaluate performance of the value chain. Assemblability is a system’s structure problem, while performance is a system’s dynamics problem. Structure of systems has been studied in the field of Systems Engineering by Network Analysis methods such as the Design Structure Matrix (DSM) (Steward 1981), and the liaison graph (Whitney 2004), while dynamics of systems have been studied by System Dynamics (Forrester 1961). Can we define a formal method to evaluate the difficulty of production of an artifact if we know the artifact’s design and the production system’s structure? This paper formulates Attribute Process Methodology (APM); a method for assessing feasibility of a DFPS project that combines Network Analysis to evaluate assemblability of the design with System Dynamics to evaluate performance of the value chain.

title	Global Visualisation Engines – Issues for Urban Landscape Planning Participation Processes
source	Digital Design in Landscape Architecture 2008, Proceedings at Anhalt University of Applied Sciences, 29-31 May 2008
summary	Traditional planning processes use two-dimensional drawings, plans, sections, elevations and artists’ impressions to communicate design intent to interested parties. Three-dimensional computer visualisation technologies that support the planning process raise institutional and organisational challenges as their perceived benefits are considered. Virtual Reality (VR) models add interactivity and immersiveness to landscape visualisations but require appropriate technical input and management. This paper explores two main themes. Firstly, how interactive 3D computer simulations of planning proposals can be adopted to successfully improve the traditional process. It reports on a pilot study to examine how architects, clients, planning officers and university researchers have worked together to systematically examine and analyse this changing process. It reports on issues concerned with ownership of city models, the roles and the compatibility, accuracy and remote sharing of urban data. Secondly, we explore the emerging theme of web-based GIS applications and their impact on architectural visualisation. The process of placing urban data onto Google Earth was tested and the resulting issues emerging with this software, including IT and data management and accuracy issues for suitable architectural visualisation are discussed. The study also reports and offers an overview of placing accurate urban landscape data onto Google Earth and a discussion of using this method for online public participation and communicating technical building information.

title	Automated Cost Analysis of Concept Design BIM Models

summary	AUTOMATED COST ANALYSIS OF CONCEPT DESIGN BIM MODELS Interoperability: BIM models and cost models This paper introduces the automated cost analysis developed for the General Services Administration (GSA) and the analysis results of a case study involving a concept design courthouse BIM model. The purpose of this study is to investigate interoperability issues related to integrating design and analysis tools; specifically BIM models and cost models. Previous efforts to generate cost estimates from BIM models have focused on developing two necessary but disjoint processes: 1) extracting accurate quantity take off data from BIM models, and 2) manipulating cost analysis results to provide informative feedback. Some recent efforts involve developing detailed definitions, enhanced IFC-based formats and in-house standards for assemblies that encompass building models (e.g. US Corps of Engineers). Some commercial applications enhance the level of detail associated to BIM objects with assembly descriptions to produce lightweight BIM models that can be used by different applications for various purposes (e.g. Autodesk for design review, Navisworks for scheduling, Innovaya for visual estimating, etc.). This study suggests the integration of design and analysis tools by means of managing all building data in one shared repository accessible to multiple domains in the AEC industry (Eastman, 1999; Eastman et al., 2008; authors, 2010). Our approach aims at providing an integrated platform that incorporates a quantity take off extraction method from IFC models, a cost analysis model, and a comprehensive cost reporting scheme, using the Solibri Model Checker (SMC) development environment. Approach As part of the effort to improve the performance of federal buildings, GSA evaluates concept design alternatives based on their compliance with specific requirements, including cost analysis. Two basic challenges emerge in the process of automating cost analysis for BIM models: 1) At this early concept design stage, only minimal information is available to produce a reliable analysis, such as space names and areas, and building gross area, 2) design alternatives share a lot of programmatic requirements such as location, functional spaces and other data. It is thus crucial to integrate other factors that contribute to substantial cost differences such as perimeter, and exterior wall and roof areas. These are extracted from BIM models using IFC data and input through XML into the Parametric Cost Engineering System (PACES, 2010) software to generate cost analysis reports. PACES uses this limited dataset at a conceptual stage and RSMeans (2010) data to infer cost assemblies at different levels of detail. Functionalities Cost model import module The cost model import module has three main functionalities: generating the input dataset necessary for the cost model, performing a semantic mapping between building type specific names and name aggregation structures in PACES known as functional space areas (FSAs), and managing cost data external to the BIM model, such as location and construction duration. The module computes building data such as footprint, gross area, perimeter, external wall and roof area and building space areas. This data is generated through SMC in the form of an XML file and imported into PACES. Reporting module The reporting module uses the cost report generated by PACES to develop a comprehensive report in the form of an excel spreadsheet. This report consists of a systems-elemental estimate that shows the main systems of the building in terms of UniFormat categories, escalation, markups, overhead and conditions, a UniFormat Level III report, and a cost breakdown that provides a summary of material, equipment, labor and total costs. Building parameters are integrated in the report to provide insight on the variations among design alternatives.

title	Integrated Design and Building System for the Provision of Customized Housing: the Case of Post-Earthquake Haiti
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 247-264.
summary	The paper proposes integrated design and building systems for the provision of sustainable customized housing. It advances previous work by applying a methodology to generate these systems from vernacular precedents. The methodology is based on the use of shape grammars to derive and encode a contemporary system from the precedents. The combined set of rules can be applied to generate housing solutions tailored to specific user and site contexts. The provision of housing to shelter the population affected by the 2010 Haiti earthquake illustrates the application of the methodology. A computer implementation is currently under development in C# using the BIM platform provided by Revit. The world experiences a sharp increase in population and a strong urbanization process. These phenomena call for the development of effective means to solve the resulting housing deficit. The response of the informal sector to the problem, which relies mainly on handcrafted processes, has resulted in an increase of urban slums in many of the big cities, which lack sanitary and spatial conditions. The formal sector has produced monotonous environments based on the idea of mass production that one size fits all, which fails to meet individual and cultural needs. We propose an alternative approach in which mass customization is used to produce planed environments that possess qualities found in historical settlements. Mass customization, a new paradigm emerging due to the technological developments of the last decades, combines the economy of scale of mass production and the aesthetics and functional qualities of customization. Mass customization of housing is defined as the provision of houses that respond to the context in which they are built. The conceptual model for the mass customization of housing used departs from the idea of a housing type, which is the combined result of three systems (Habraken, 1988) -- spatial, building system, and stylistic -- and it includes a design system, a production system, and a computer system (Duarte, 2001). In previous work, this conceptual model was tested by developing a computer system for existing design and building systems (Benr__s and Duarte, 2009). The current work advances it by developing new and original design, building, and computer systems for a particular context. The urgent need to build fast in the aftermath of catastrophes quite often overrides any cultural concerns. As a result, the shelters provided in such circumstances are indistinct and impersonal. However, taking individual and cultural aspects into account might lead to a better identification of the population with their new environment, thereby minimizing the rupture caused in their lives. As the methodology to develop new housing systems is based on the idea of architectural precedents, choosing existing vernacular housing as a precedent permits the incorporation of cultural aspects and facilitates an identification of people with the new housing. In the Haiti case study, we chose as a precedent a housetype called ‚Äúgingerbread houses‚Äù, which includes a wide range of houses from wealthy to very humble ones. Although the proposed design system was inspired by these houses, it was decided to adopt a contemporary take. The methodology to devise the new type was based on two ideas: precedents and transformations in design. In architecture, the use of precedents provides designers with typical solutions for particular problems and it constitutes a departing point for a new design. In our case, the precedent is an existing housetype. It has been shown (Duarte, 2001) that a particular housetype can be encoded by a shape grammar (Stiny, 1980) forming a design system. Studies in shape grammars have shown that the evolution of one style into another can be described as the transformation of one shape grammar into another (Knight, 1994). The used methodology departs takes off from these ideas and it comprises the following steps (Duarte, 2008): (1) Selection of precedents, (2) Derivation of an archetype; (3) Listing of rules; (4) Derivation of designs; (5) Cataloguing of solutions; (6) Derivation of tailored solution.

title	Mapping the intangible value of urban layout (i-VALUL): Developing a tool kit for the socio-economic valuation of urbanarea, for designers and decision makers
source	H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary	In this paper we present the development of a GIS tool kit for the socioeconomic valuation of urban areas towards the creation of sustainable communities, describing the project context, development process, the tool kit’s structure, its main tools and initial feedback from its use. We then present the plan for training sessions and pilot projects where the tool kit is going to be used, and conclude with the discussion of the development of a single integrated tool to be used beyond the life of the ‘i-VALUL’ project. This project was supported by the UCL led UrbanBuzz programme within which UEL is a prime partner.

summary	This paper introduces new supporting tools in the field of distant collaborative design, namely DCDS and CRTI-weB. These prototypes respectively support: the early stages of design, through the support of the crucial initial step of free-hand sketches shared in real-time, and the asynchronous collaborative activities. The main goal of this paper is to propose the use of these innovative tools as an efficient and realistic way of managing long distance collaboration, to effectively serve the designers’ needs. This proposition is analyzed and addressed through a real-size experiment featuring 30 architecture and architectural-engineering students, working together in real-time at different locations (Belgium and France). This experiment and the necessary survey open up interesting fields of investigation, such as the relevance of the proposed services in supporting distant collaborative design in architecture and the benefit this represents for students to merge the IT aspects and the design studio. The methodology and the replicability are analyzed to increase the level and quality of formation of our students and, finally, a criticism of the tools confirms a benefit for the developing teams.
