INTRODUCTION The world economy globalization fosters the increase of architect services and business sector development in Indonesia. The development in the field of construction services creates a higher intensity of competition between companies and architects. With the existence of competition brings fact of the need to have a competitive edge or competitive advantage over the other company. One way to have competitiveness is lies on architects through improvement of their work performance. In this study, architect’s work performance will be put as primary focus because architects are the conceptor of any planning/development idea. In Indonesia, Architects have a unifying platform of Ikatan Arsitek Indonesia/ IAI (Indonesian Architects Association) as stated in Republic of Indonesia Law No.6 of 2017 concerning Architects. This law also regulates the duties and responsibilities of architects together with their rights. Ikatan Arsitek Indonesia has administrators in each province and certain cities/regencies, including in Malang where the management for the Malang Region is covering Malang City, Malang Regency and Batu City (Malang Raya). Technological innovation and intense business competition these days push consulting firms and architects to change the way they do business. To keep their competitive edge, consulting firms and architects must make a quick change in their strategies from original idea that prioritizes labor (a labor–based business) that get mixed with implementation steps into a knowledge-based business development that prioritizes solely on specific feature as a designer architect or planner, thus make its main characteristic more to a science.

Nevertheless, researches on Intellectual Capital are still inconsistent especially in relation to company performance. Firer and William (2003) stated that physical capital is the most significant factor that affects company performance, thus there is no positive influence between intellectual capital and company performance. However, Houari et al. (2014) stated that there is a relationship between intellectual capital and the leadership process. Darmayanti et al. (2014) also stated that intellectual competence and work motivation have a positive and significant effect on work performance. II. LITERATURE REVIEW A. Work Performance According to Pasolong (2008: 197), the concept of work performance can basically be seen from two aspects of employee work performance (per-individual) and organizational work performance. Employee work performance is the result of individual work in an organization; meanwhile, organizational work performance is the totality of the work achieved by an organization. Employee work performance and organizational work performance are very closely related. The success of achieving
