What is the main objective of Quality Assurance?

The main objective of Quality Assurance (QA) is to ensure accurate processes are in place. QA focuses on the systematic processes that are put in place to maintain quality standards throughout the data collection and management lifecycle. By establishing and following standardized methods, QA helps in preventing defects or errors in the GIS data collection and analysis procedures. This proactive approach allows organizations to identify potential issues before they occur, leading to consistent and reliable results in GIS applications.

While validating data after collection is important, it falls under Quality Control (QC), which is more about checking the quality of the final products rather than ensuring that the processes leading to those products are accurate. Measuring performance outcomes typically relates to assessing the effectiveness or efficiency of processes rather than the processes themselves. Analyzing spatial distributions pertains to spatial analysis tasks in GIS but does not directly align with the overarching goals of quality assurance. Thus, ensuring accurate processes is fundamentally what QA aims to achieve in any GIS environment.
