Randomized field trial shows significant cost reduction in construction projects, indicating process-control systems' effectiveness.

To evaluate the cost-effectiveness of different process-control systems in Senegal's construction projects.
Conducted a randomized field trial assessing performance metrics of process-control systems
Applied statistical analysis using linear regression models with robust standard errors
Determined cost-effectiveness ratios for the assessed systems.
System A achieved a 15% reduction in project costs compared to baseline levels
Statistical significance confirmed with p < 0.05
Field trial highlighted the efficiency of process-control systems in reducing costs without compromising quality.

Diop et al. (2013) studied this question.
