The first thing I did to get a better understanding of the company and the problem was to read the project briefing and study the business and the context. Then, I used some tools to better organize the information for the official project kick-off with the client.

About VLI

VLI is one of the largest integrated logistics operators in Brazil, with 4,800 km of rail, eight operating transshipment terminals and six port terminals. The company transports millions of tons of agricultural products and steel products, which are critical to the Brazilian economy.
VLI’s transportation operations are concentrated along five strategically located corridors with a high degree of logistics integration in the main regions of Brazil, producing goods and industrialized steel, agricultural and mineral products. The Center-North corridor, for example, makes an essential contribution to the development of the new agricultural frontier in the country, notably in the handling of grains. The Center-Southeast corridor is another example of strategic positioning, representing one of the leading export routes through the Port of Santos and the Luiz Antonio Mesquita Integrator Port Terminal (Tiplam), carrying mainly sugar and grains.
