Systematic observation allows the understanding of each phase of a task, allowing the researcher to understand every thing that happens, generating a comprehensive and complete conclusion.
Explanation:
Systematic Observation is a method used to understand how a particular activity or task works. The researcher observes the stages of a process, the tools used, the difficulties that appear, the conversations and the results of the work. Systematic Observation is guided by a definite goal, one thing one wants to know about that activity. The observation is made over and over until there is sufficient evidence to assert such a thing.
Systematic Observation can be used to do Behavioral Mapping, Task Analysis, or Activity Analysis.
