This survey results show that the top five priority strategies are: 1st “Increasing Revenue" to develop business, 2nd “Promoting Lean Service" to not to waste, 3rd “Cutting Cost" and 4th “Reducing Leakage Rate" to reduce cost and 5th “Promoting Human Capital" to reform culture. The end priority strategies are most of national policy and corporation social responsibility, although they are not urgent, TWC may search new niches within them and accomplish CSR.
