Mixed-methods study demonstrates that financial barriers directly impair Six Sigma project success in service companies, highlighting the critical role of resource allocation.
Key Points
To identify Six Sigma barrier factors and evaluate their structural relationship with project success in service organizations.
Implemented a mixed-methods design comprising qualitative case studies across 12 service firms and a quantitative survey across 98 companies in Tunisia.
Tested the structural model using partial least squares structural equation modeling (PLS-SEM) in SmartPLS3.
Demonstrated significant interrelationships between cultural and training barriers, statistical and financial barriers, and organizational and cultural barriers.
Financial barriers exerted a statistically significant direct negative impact on Six Sigma project success, whereas organizational barriers showed no statistically significant direct effect.
