A novel lean briefing process for effective design management

El Reifi, Mohamed Hani January 2016 (has links)
Construction projects experience design changes and much time and effort is put into trying to address fluctuations in client and project requirements; however, in many cases, insufficient value is delivered to the client. The successful use of Lean Management in the construction stage has opened up the possibility of using it in the design stage – thus helping to establish a systematic approach to managing construction projects and business. Attention is turning towards Lean Design Management to address deficiencies in the design phases that many would argue should have been dealt with in the early project delivery stages. Aspects of ineffective briefing process practice have been shown to have negative consequences and implications for the efficient performance of design management. The client is asked to provide requirements without ensuring that they have established sufficient knowledge of the project to do so. These requirements, most likely, will change then over time, because in most cases the initial decision was not made based on sufficient project knowledge or a well-established vision. The client needs to be made smarter and to learn about the building early on in the project, long before the architect sketches the concept design.

Méthode de conception de produit intégrant ses services en phase conceptuelle appliquée aux projets de construction / Method for the conceptual phase of an Integrated Product and Service Design applied to Construction Project

Mauger, Cyril 19 December 2014 (has links)
La phase conceptuelle, basée sur des informations imprécises et incomplètes, est à la base de la satisfaction des clients par le futur système. La programmation architecturale se concentre sur une des premières étapes de cette phase dans le domaine de la construction : la définition des besoins d'un bâtiment. Les pratiques et recherches actuelles en Architecture-Ingénierie-Construction ont tendance à être basées sur l'expérience des programmistes et architectes. Elles sont rapidement orientées vers la production de solutions architecturales et avec une formalisation tardive des besoins métiers en exigences bâtiment. La définition des exigences est bien plus développée dans les autres domaines d'ingénierie (i.e. génie mécanique, industriel et logiciel) au sein de théories, modèles, techniques et outils. Ces travaux de recherche visent à proposer un raisonnement de programmation architecturale basé sur ces connaissances en matière d'ingénierie des exigences dans ces autres domaines. La méthodologie suivie pour développer ce raisonnement s'appuie sur une démarche transdisciplinaire basée sur une combinaison de méthodologies issues des Sciences de la Conception. Outre l'identification de langages de modélisation couvrant différent points de vues associées à la programmation architecturale, un manque est identifié en ce qui concerne les concepts définissant l'objet d'étude : la transition entre les concepts d'activité et d'espace. Le concept de ‘‘méta-espace'' est proposé pour combler ce manque ainsi qu'un langage de modélisation permettant l'exploitation des relations entre ces concept. Une formalisation très en amont de la transition des besoins métiers des clients vers les exigences bâtiment est proposée via une démarche conceptuelle résultant de l'ajout du concept de ‘‘méta-espace''. Cette démarche est présentée étape par étape en s'appuyant sur les divers cas d'études traités au cours de la thèse. / The conceptual phase is based on very fuzzy and incomplete information about clients' needs. It constitutes the core of clients' satisfaction about the future system. Architectural programming, or briefing process, focuses on the early stages of the conceptual phase of construction projects, i.e. the requirements definition. Current practices and research in Architecture-Engineering-Construction tend to be experience-based, solution-oriented, and with a late formalisation of business needs into building requirements. The requirements definition is far more supported by theories, models, tools, and techniques in other engineering disciplines (i.e. Mechanical, Industrial, and Software Engineering). This research aims to propose an architectural programming reasoning based on existing requirements engineering knowledge from these other engineering disciplines. The methodology followed to develop this reasoning is a transdisciplinary approach based on a combination of Design Research Methodology, and Design Science. Besides the identification of modelling languages covering different viewpoints associated with the briefing process, a gap is identified regarding modelling constructs associated with a “meta-space” design artefact. This design artefact and its associated modelling language (i.e. the meta-space diagram) support the formalisation of the transition from activities to space. The resulting conceptual framework proposes a step by step early formalisation of the transition from clients' business needs to building requirements. All along the thesis, different case studies are used to illustrate the proposals.
