An investigation is the process of gathering facts and evidence to examine and evaluate a subject, event or issue. They’re common in corporate, regulatory, or criminal contexts and can be used to determine the truth, assess compliance, or hold individuals accountable for their actions. Investigations provide clarity, promote transparency, and help ensure that action is taken based on facts and evidence.
A well-written report is the backbone of any investigation. Whether you’re an HR professional investigating a workplace harassment claim or a law enforcement officer building a criminal case, the quality of your report directly shapes its outcome. The goal is a clear and defensible story that delivers your findings to stakeholders, with zero speculation or opinion.
To deliver that, you’ll need to be able to handle a variety of evidence types. It’s a skill that investigator certification programs like McAfee Institute build into their training, teaching professionals to write with undeniable objectivity and document their methods in a way that stands up to legal scrutiny. Almost any modern investigation involves a mix of physical, digital, and testimonial proof. Knowing how to deal with each of these is essential to a strong investigation, and it starts with ensuring you have a rock-solid chain of custody. This means a detailed log of everyone who touched your evidence, when, and why. It also means recording interviews (with consent, of course) and transcribed to preserve testimony. Lastly, digital evidence can be extremely fragile and difficult to manage, so using forensic tools and following best practices is key.
