The correct answer is Systematic observation
Systematic observation is a method used to understand how a particular activity or task works. The researcher observes the steps of a process, the tools used, the difficulties that appear, the conversations and results of the work.
Systematic Observation is guided by a defined objective, something you want to know about that activity. The observation is made repeatedly until there is sufficient evidence to state this.
Systematic Observation can be used to do Behavioral Mapping, Task Analysis or Activity Analysis.
