The nature, characteristics and traditions of the Architect, Engineer and Construction (AEC) Industry can be a challenge for enabling innovations and development. As projects are limited in time and scope and often under cost pressure, it can be difficult to prioritize time to innovate. However, as we recognize the negative impact our industry has on e.g., climate changes, loss of biodiversity and social inequalities, the industry needs to change and develop at a higher pace. If we want to be part of the solution and not the problem, we need to ask some very important questions on e.g., the methods we work by, the solutions we design, and the materials we use. Lean methods like Choosing by Advantages (CBA) have proven to enable cross disciplinary and collaborative decision making. But CBA could also set the framework for targeted innovation and development within a project setting. This paper presents the idea of how CBA could support targeted innovation within project constraints. The method was tested on a case, where the client was seeking improvements within specific areas compared to a 'standard' solution.
