Abstract

PT X is a construction company with clients spread among Central Java, West Java, Papua, Kalimantan, and Sulawesi. This company experienced financial problem and with the absence of financial bookkeeping, the financial issue was difficult to trace and each manager and also the owner had different perceptions toward the financial problem. One said that it was caused by bad financial investment decision, many said that it is because client late payment, while the other said that it is due to lack of orders and competition. In other word, this problem is still a perceived financial problem. This research was conducted to find the root cause of perceived financial problem in PT X as well as to find the best solution to solve it. By establishing 2 methods that consisted of fault tree analysis (FTA) and fuzzy analytical hierarchy process (fuzzy AHP), employing the thinking framework of value-focused thinking (VFT), the best solution was decided. FTA was used to identify the root cause of the problem which was bad investment decision. After that, reverse brainstorming was conducted to find all possible solutions. Before jumping into alternative solutions, VFT, a thinking framework, identified that control and simplicity was the value that the owner considered. 3 alternative solutions which were asking to financial consultant, hiring financial analyst, and training current financial manager, then analysed using fuzzy AHP with context suitability, sustainability, time needed, and cost as the criterion, and found out that training current financial manager is the best alternative to be chosen.
