Worksafe BC (WSBC) is an organization dedicated to promoting workplace health and safety for workers and employers across the province through regulatory enforcement, education and by offering workers insurance and compensation services. On an ongoing basis, WSBC invests substantial funds in safety awareness and injurt prevention programs. Intuitively these programs result in improved safety performance and awareness, and WSBC continues to fund these programs. A challenging problem for WSBC is understanding how much benefit and to what extent each investment is contributing. WSBC is interested in knowing this so they may consider the best portfolio of programs to maximize safety performance in BC. The goal of this project is to provide recommendations for assessing the effectiveness of the various programs.
