Theoretical Framework LITERATURE REVIEW

93 Figure 2.6. Proposed Status to Convert Tacit Knowledge to Explicit Source: Nissen, 2006 Referring to the literature for knowledge conversion process see 2.3.2, there are two main elements to capture knowledge: 1 one is the knowledge which has to be converted and, 2 a proper technique to do this conversion. Because, this study is concerned with the knowledge required during the conceptual design phase, therefore we need to be more focused on this stage. Toward this goal, existing models for this stage have been examined to choose an appropriate one. Indeed, this study attempts to provide a linkage between the required knowledge and the conceptual design activities. Therefore, selected models have to include sufficient details for the activities. To this end, after comparing existing models, Macmillan 2001 framework Explicit Tacit Existing Flow proposed by Nissen 2006 Proposed Flow by this study 94 has been chosen as an appropriate model which was usable to make a linkage between activities and the required knowledge.

2.6 Summary

In this chapter, the literature survey about knowledge management process, knowledge flow and also design process allow the researcher to constitute a theoretical framework on the basis of the discovered related background theories concerning capturing tacit knowledge of experts during conceptual design stage. The study proposes using Nissen 2006 multidimensional model to examine the knowledge flow of different typologies and members. Since the selected area for this study is conceptual design phase of a building project, the study proposes Macmillan framework, which includes sufficient details for capturing tacit knowledge between different members. By adopting these two theories the thesis proposes two propositions for the study: Proposition 1: Knowledge capture can be improved when design professionals know what the required knowledge are and when they are needed during conceptual design phase. Proposition 2: With improved knowledge capture, design professionals can improve their knowledge transfer and application during conceptual design phase. 95 CHAPTER 3 RESEARCH METHODOLOGY

3.1 Introduction

In this chapter, the performed case study research is explained. Furthermore, the researcher expresses the reasons for choosing this methodology to solve the stated problem. Then, components of selected methodology, data collection procedure, unit of analysis, and data analysis are elaborated. Objectives of this study are explained below: Objective 1: To specify an appropriate knowledge capture technique for tacit dominated conceptual design phase. Objective 2: To identify fundamental mechanicalelectrical requirements to be considered by architects during the conceptual design phase. Objective 3: To develop a framework for capturing fundamental tacit mechanicalelectrical requirements during conceptual design phase.
