Abstract
This study presents a methodology used in developing the competitiveness improvement framework (CIF) for laboratories, in particular, Forensic Science Laboratories (FSLs). The cyclic nature of FSL processes allowed data collection for the purpose of identification of factors affecting FSL performance (cause factors). Flow charts were used to represent mathematical formulations for cause factor measurements and quantification of the baseline data on turnaround time (TAT), backlogs for case files (Bg), turnaround time in the supply chain (Tsc), and employee absenteeism (Ab). By quantifying the cause factors in addition to academic development coefficient (Ad) and complex longevity (Lc) for FSL employees, it was possible to establish the organizational design features requiring improvements. The relevance of cause factors to FSL stakeholders and means of improvement and sustainability were established. A detailed road map towards CIF was presented using D-MAIC methodology. The rated cause factors based on challenges in the FSL business environment were subjected to Pareto analysis to prioritize the challenges in order to improve FSLs’ competitiveness. The interrelationship between the three dimensions of competitiveness improvement (process, performance and planning) was presented in terms of the affected six cause factors. Also, the potential lean practices for improving competitiveness of FSL based on measured cause factors have been presented. This paper introduced methods and measures for improving operational competitiveness of laboratories. The CIF was finally presented in a form of a series of three flow charts summarizing all steps implemented in its development with inputs and cause factors involved.
Highlights
For forensic toxicology, improved performance was observed, for instance, at a given TAT2 of 50 days, 60% of case files were completed in Y2014 which increased to 85% in Y2015
The development of competitiveness improvement framework (CIF) based on captured variations in the laboratory processes including fluctuations in turnaround time (TAT) between different case files, between different action points and different laboratory disciplines enabled a deep understanding of process variations, via statistical analysis (CDFs)
The results show that the extent of backlogs is alarming necessitating action
Summary
Need for Developing the Competitiveness Improvement Framework for FSL. The FSL consists of a series of connected processes beginning at SRO’s office (when samples arrive) and ending at the same area where clients collect their analytical reports. The critical performance measures and cause factors were identified in order to develop the CIF. The contribution of this study to the global knowledge is mainly on forensic science laboratory management, which is a new research area involving competitiveness improvement. After establishing the baseline performance data, the study scope was extended to locating areas of improvement and the approach. The study area started from the time samples/exhibits are submitted to the laboratory to the time when a report is released
