Architects do not perceive themselves as entrepreneurs. Additionally, the necessity to engage with this topic has not yet reached small architectural firms. However, only with entrepreneurial thinking can they master the current prevailing conditions and challenges, thereby successfully competing in the market. It is important to view the firm as a whole and not just focus on individual aspects. The developed overall strategy, the Success Model for Architectural Firms, outlines which areas the firm owner needs to manage, as well as their dependencies and connections. It also includes what the firm owner can improve in each area and how to achieve that. This strategy is exemplary for every architectural firm. The Success Model for Architectural Firms is clearly structured, allowing every architect to identify their problem areas.
