The book "Uso de sistemas de informação em ferramentarias" by Alceri Antonio Schlotefeldt examines the role of information systems in the tool manufacturing industry, particularly in the production of injection molds for plastics. It argues that the use of such systems not only increases the efficiency of operational processes but also reduces response times to customers. This can lead to higher customer satisfaction and an improved corporate image. The study is based on the premise that tool manufacturing companies can become better organized and more competitive through the implementation of information systems. The research provides valuable insights into the necessity and benefits of information systems in a constantly changing market.
