The success of business process re-engineering (BPR) is dependent on the use of data-driven methods that provide cost-effective and optimal solutions. Today's business managers are inundated with methodologies and tools that claim to provide sustaining process improvement results. Determining
the appropriate BPR method(s) to employ is a daunting task for many businesses. Understanding the technical complexities of these methods is even more overwhelming. However, with the increased availability of management science software, business managers can easily identify and employ proven
management science techniques. Readily available software that provides timely results, is easily adaptable to resource changes, and does not require extensive technical competencies. This paper demonstrates how scientific management techniques, coupled with management science software (Management
Scientist, Project Management and Excel), provided a feasible and achievable solution to a laboratory courier service BPR project. The solution yields a 19.5 percent reduction in annual laboratory courier specimen costs while improving service levels.
