ABSTRACT
What is the relationship between design of activity and time study? At rst glance, these are two independent problems. However, in reality, they are closely interrelated because activity or behavior is a process. In essence, when we set ourselves on designing activity, it is necessary to understand that we have to design a process that unfolds over time. More precisely, activity is a complex structure that consists of various elements that are unfolding over time. In Section 7.3, we demonstrated that the time structure analysis is a critically important stage of ergonomic design. However, there are a number of other issues related to the time study in ergonomics. These issues will be discussed in this section.
