Introduction to Evidence-Based Practice and Its Core Principles

At the heart of 3CO02 – Principles of Analytics, AC 1.1 asks learners to explain what evidence-based practice is and how it is applied within an organisation. This video addresses that criterion directly, tracing the origins of evidence-based practice in medicine during the 1990s before examining how the approach has since been adopted by people professionals. It introduces triangulation as a method for drawing on multiple sources of evidence, and frames systematic decision-making as a deliberate alternative to relying on habit, precedent or intuition alone.

The video identifies three core principles that underpin evidence-based practice: critical thinking, transparency, and humility. Each principle is treated as a distinct component of how practitioners approach judgement and decision-making at work. Confirmation bias is named as a cognitive obstacle that evidence-based approaches are specifically designed to counter, and the principle of transparency is examined in terms of openness about both the evidence selected and the limitations of any given analysis. Humility is discussed in relation to the boundaries of personal professional experience and its reliability as a basis for organisational decisions.

To anchor these principles in a workplace context, the video works through a recruitment scenario to illustrate how evidence-based practice differs from trend-following or imitation of previous employer practice. Three guiding questions — concerning what the evidence shows, how reliable and relevant it is, and what different courses of action might produce — are presented as a structured way of applying the approach before a decision is made. Together, these elements cover the indicative content for AC 1.1, addressing both the nature of evidence-based practice and the way its components inform principle-led judgements and outcomes within an organisation.
