The first stage of assessment involves the collection of data from primary and secondary sources. This is a critical process as it lays the groundwork for all subsequent analysis and evaluation. Collecting data from various sources ensures a comprehensive understanding of the subject being assessed. Primary sources provide real-time, first-hand accounts or data directly from the patient or the field, while secondary sources offer insights from existing research, studies, or analyses that can help contextualize the primary data.

This stage is essential because accurate and thorough data collection serves as the foundation for effective assessment, influencing how later stages, such as analysis and validation, are approached. The quality and breadth of data collected directly impact the reliability and validity of the conclusions drawn in later evaluations. Without this foundational step, assessments may lack the necessary depth and accuracy needed for sound decision-making or strategic planning.
