What does chronoanalysis have to do with lean manufacturing?

Have you ever asked yourself this question: what does chronoanalysis have to do with lean manufacturing? Well, if we assume that the heart beat of Lean Manufacturing is tact time, we will notice that these two themes are closely intertwined. The chronoanalysis aims at obtaining the standard time, making all statistical considerations applicable and can be used to, among others, balance production lines, increase efficiency, increase efficiency, reduce costs, rationalize production, of course, whether we are meeting the tact time. A chronoanalyst (be it an engineer, administrator, technician and others) needs to keep in mind that there is no point in increasing the efficiency and productivity of a process if there is no greater demand for that product produced or the need to produce other items in that process. What I mean by all this is that what good would it do me to do a super study in order to produce more if there is not enough demand to produce more? I would have to buy more raw material to meet the demand of the process (money coming out of the box) and increase my stock (money that is stopped in the system). This would give a bad financial imbalance and could generate the opposite of expected within the company.
