Aim - This research was done in one organizational medium-sized unit (around 250 workers) in Belgrade. This research will try to give some crucial ideas how to shorten production cycle using modified method of current observations through observing that production cycle. Field observation should recognize slowdown in chosen production and should define it statistically and dinamically. Using good definition and slowdown recognition further analysis should offer new technical solutions or functioning models how to make better and faster organization of all production cycle. Methodology - Research that will be done by observing production cycle water meter installation on Sample 1 in Belgrade means registering, data gatehering and observing production cycle, measuring of production and non-prodution times, ideas on observations, appearance descriptions, presentation of certain appearances by means of parameters (working time, number of done pieces, working spped, location of machinery, number of slowdowns and reqasons of slowdown) Analysis will be planned to give as much as possible descriptive and number data. Results - Obtained results show the influence of observations (regfistering) of the chosen production cycle and nitification of certain appearances such as slowdown caused by certain factors. By defininfg reasons we can define some other problems in the organiyation such as: bad work organization, unmotivation, technological out-of dateness. Research restrictions - The research that is done and presented was done for just one cycle by random choice. Its limitations are concerned the time, i.e. it couldnt monitor all the production cycles for the whole unit, but that will be done in future. Such research asks for continous observing during several months and then it asks for some time in order to prepare data. On the other hand, this research was done in 15 days on randomly chosen sample. Having in mind that the whole company consists of 250 workers, we can say that we observed cycle of 15-20% of the whole production. Originality and validity - This research is necessary because it can show possible problems that occur in medium size company production adn it emphsizes certain practical problems. It also shows slowdowns presence and how often they are how they influence on production cycles and how they decrease business efficiency.

Purpose -This research was done on one sample (20 workers of different profiles and qualifications) in Zrenjanin. The Reason of this observation was the aim of observing occurences in small workshops using the modified method of current observations reggardless type of production and technology. The object of observations was one cycle of installing all necessarry parts for the machine that produces shaped plate. Methodology - We used methodology called the method of current observations, but slightly modified. The stress was put on the cycles where main actors were tools and people. The technology of observations consisted of cycle observations, gathering and notifying the gathered data and further analysis of the data. We didn't ask the workers directly in words or by a poll, but we did our observation without any contact with the employees and all the employees had been told to do their jobs naturally without having sense of being observed. Results - Gathered data show several factors that resulted from the observation that lasted several months, and in this paper we analyzed just research of 15 days with 25 observations. Further data showed possible slowdowns, which were statistically analyzed, and the most common types of slowdowns. Limit in the research - limitations of this research was just limitations connected to the number of cycles and the type of cycles that were observed. This company has several cycles that have certain technology, but due to the aim and the form of this paper only one cycle is the key cycle, because it is the most common and it demands the most operations. Originality and value - this research is specific because the method of current observations is known in modern literature, but its modification is something new and it is not analyzed enough. Such a topic is not known in domestic industry, which has many technological and financial problems, and there isn't adequate climate in it that can enable observations of cycles (and workers) using the method of current observations.

Professional orientation in no longer connected only to helping young people to choose the vocation, but it is now often connected to changes in vocation structure and needs to retrain the employees. From all these reasons, professional orientation includes not only help to choose the vocation, but also it includes the tracking of an individual during his career, either for his needs in adaptation, stabilization on his job and further education or for the need to change the vocation.
