Takt production has recently received increased attention in both the construction industry and academia. However, the research on takt production has focused on documenting single successful cases, while attempts to holistically explore the impact of takt production on construction production flow are scarce. To address this knowledge gap, this study aimed to build a theoretical model of how takt production contributes to construction production flow. A qualitative multiple-case study was conducted to validate propositions based on a literature review, and the results were discussed and synthesized in the form of a theoretical model. The findings indicate that while takt production is a viable method to increase flow, it requires significant effort in terms of planning, control, and continuous improvement. While having a positive impact on process flow (location flow), the effects on operations flow (trade flow) are contradictory. The study has implications for further comprehensive evaluation of the effects of takt production on construction production flow while facilitating more predictable, systemic implementation of takt production across projects.

This study addresses the possible ways to improve takt implementation in projects. The purpose of this study is to gain knowledge of the stakeholder commitment and collaboration in takt projects where takt production is implemented. The study aims to explore which enablers and barriers affect collaboration in takt implementation projects, and how they differ between cases in Finland and California.The study was conducted as a qualitative multiple case study. The case projects were purposefully chosen for this study. The data collection was conducted as a triangulation of interview, observation and documentation observation. The enablers and barriers from different cases were clustered into plusses, deltas, and drivers between Finnish and Californian cases as well as jointly. The results were then analysed in a workshop and recommendations for further takt implementations as well as further research were made.Recommended actions for further takt implementation cases of more complete Lean understanding, and more transparent partnership between trade partners. However, the results and recommendations are based on a single study with a limited amount of cases, and therefore further research inside the topic is needed.

Takt production is gaining increasing visibility in the construction industry. To further improve the current takt production practices, visual management tools could offer improved efficiency in the production control phase. However, the effects of visual management in takt control setting have not yet received much attention in research.This study aimed to investigate the effects of various visual tools in a takt production setting to gain knowledge on how these tools could aid takt control efficiency. The research utilized a design science research approach to create visual management tools and iterate them based on feedback. Interviews, site observation, and takt progress tracking were used to evaluate the implemented tools.The findings indicate that workers on site want to be more aware of the production plan, and information helps them to work in the right location at the right time. To help workers, visual management tools need to recognizable, explicit, and contain correct and up-to-date information. However, there are cultural issues related to implementation, especially on the need for information going through foremen to crews.
