Kinds of Students in Fib Ui

...Second Draft KINDS OF STUDENTS IN FIB UI There are three main kinds of students in FIB UI based on my one year observation of being an FIB UI student. The first and the most common one is organization oriented students or what we call “Kura-Kura (Kuliah-Rapat)” students. These students are a member of more than two organizations or become a committee in some of events. They spend mostly of their times for having some meetings. Some of them usually find themselves hard to manage their time for studying and for their organizations. However, some others can still manage their time well. My friend, Putri, for example, has at least four meetings every week, but her GPA is always above 3.5, which means she can still manage her time effectively. The second one is study oriented students or what we call “Kupu-Kupu (Kuliah-Pulang)” students. They are not a member of any organizations, nor a committee of any events. They spend their time in campus to study and read books at library. One of my friends, Annissa, for example, studies harder than everyone and prefers to go home directly after the class has been dismissed than to have meetings. However, she still likes to play or chat with her friends, not really a nerd type. The third one is “Kunang-Kunang (Kuliah-Nangkring)” students. They spend most of their time in campus cafeteria. My brother, Wanda, who already graduate from bachelor degree for instance, spent most of his time in campus chatting with friends in campus cafeteria and playing...

I found out that there are companies where folks are happier and more effective once the jobs are standardized and when the ambiguity is decreased.

Business Dilemma

...undefined. My partner and I were in dire need of separating daily tasks and still being able to feel as though everything was getting done. This has been a difficult problem to deal with because I feel that I have a certain way of doing things and that others will not take the proper steps to ensure everything is done correctly. The question The largest question at hand was how we could evenly split up the responsibilities while ensuring that neither managing member felt as though their workload was unfairly more than the others and that things would still be completed effectively. To answer this question, we had to ask a number of other questions. These questions ranged from, “What different kinds of tasks need to be completed and what are those tasks?” “What kind of time constraints were we under, including family, work and school?” As well as a number of other questions we needed to address. The research question(s) The questions narrowed down to a few specific problems that we needed to work on understanding. First, should we hire more instructors in order to better focus on the growth of the business as opposed to constantly working for it? Second, is there a way for each of us to train the other on what we do regarding our current responsibilities with the business? Finally, how much additional time could we each dedicate toward improving and learning our new tasks? Because we have been so sporadic with the responsibilities that we have taken on...
