The purpose of this study is to design, develop and evaluate an electronic performance support system (EPSS) for the crime scene investigation unit (CSI). For this purpose, a sequential explanatory strategy as a procedure of the mixed method design was used in analysis and evaluation of the EPSS. The research was composed of three main phases: analysis; design, development and implementation, and evaluation of the EPSS. In first phase composed of performance and cause analyses, the CSI Unit’s existing information, and contributing causal performance factors based on Gilbert’ Behavior Engineering Model were explored. In performance analysis phase, official documentation of the CSI Unit was reviewed. As for cause analysis, the survey and focus group interviews were conducted to 1176 and 22 CSI officers, respectively. These data were analyzed using with both quantitative and qualitative methods to facilitate the selection of the most appropriate intervention and its components. Analyses results revealed that 14 basic influences grouped under the workplace and competency on human behavior impacted performance of the officers. Based on these results, an EPSS composed of intrinsic, extrinsic and external levels, and support components was designed and developed in the second phase. Having been implemented, the evaluation of the EPSS based on the Kirkpatrick’ Four Levels of Evaluatıon Model was conducted v to determine the overall impact, perceived benefits, and effectiveness of the intervention in third phase. In this phase, a survey, interviews, computer logs and a checklist were used so as to assess the accomplishment of the EPSS. While the survey and the checklist were administered to the 191 officers and 2 experts from the field, the interviews were conducted with 12 officers. Evaluation results admitted that the CSI officers’ reactions were very positive to the EPSS. While, an intrinsic support made a major contribution to their productivity, establishing standardization would be perceived as the major impact of the EPSS. Lastly, increasing identity and simplifying criminal justice system were the two main impact factors on the society that the system would influence positively.
