Case studies are an effective publication method used to document the facts and analysis of a specific observation or incident. The content and format of a case study can vary depending on several factors, including the purpose of the case study, the degree of analysis available at the time of the report, the derived lessons learned, and any recommendations. Michael G. Koehler, Ph.D. recently published this commentary which outlines the guidelines for writing an effective case study. The paper is available at this ACS Chemical Health & Safety website link for a limited time, or download the pdf file here. Great work Dr. Koehler!
