1 Developing a Framework for Knowledge Management System: The case of Flintstone Engineering SC. Fitsum Seifu HiLCoE School of computer science and technology fitsumseifu@yahoo.com Temtim Assefa School of Information Science Addis Ababa University temtim@yahoo.com Abstract Knowledge is a principal source of wealth in the present day business. Construction activity is a knowledge-based activity which uses knowledge as a critical resource in daily organizational activities. Eliciting the current organizational knowledge and proposing knowledge management system (KMS) framework is the main delivery of this research project. The proposed framework is used as a guide to implement KMS in the construction industry. Flintstone Engineering SC. (FE) which is one of the industries major player was selected as a case study for this research project. This research project was conducted to elicit FE organizational knowledge areas and to develop a KMS framework for FE. Process oriented approach was used to elicit organizational knowledge from domain experts. Interview was used as knowledge acquisition method. Elicited knowledge was analysed using open coding method to develop knowledge taxonomy and KMS framework. Using open source content management system, Drupal, prototype KMS developed to evaluate its relevance. Keywords: Ethiopian construction industry knowledge management system; construction industry knowledge management system framework; Ethiopian construction industry knowledge management 1. Introduction Knowledge becomes a principal source of prosperity in a present-day economic era called “knowledge age” or “knowledge economy” (Savage , 1996) (Sunassee & Sewry, 2002). Collective employee’s knowledge in producing state-of-the-art competitive products and services assisted by technological improvements and innovations is tapering competition gap between organizations (Sunassee & Sewry, 2002). Organizations consider knowledge as a key and most treasured resource for their business success (Nonaka I. , 1994). Knowledge which is an intangible asset of organizations and its management has become an issue to organizations since early 1990s (Sunassee & Sewry, 2002). Traditional production factors such as labour, capital, and land are no longer adequate to withstand the competitiveness of organizations (P., 1986).Through effective KM, an organization gains competitive advantage by sharing and reusing knowledge (Abdullah, Sahibuddin, Alias, & Salamat, 2005). KM using collaborative technology can be used to avoid information overload, utilize technology improvement, upsurge professional specialization, provides an advantage for competition, reduce effects of workforce mobility and turnover, and capitalization of organizational knowledge (Abdullah, Sahibuddin, Alias, & Salamat, 2005). Implementing KM in construction industry using information technology; Alavi et al. (Alavi & Leidner, 2001), tried to show the use of information technology deployment to facilitate, support and enrich organizational processes of knowledge conception or establishment,
