Every DSI Project is a Learning Process for the Customer

Our experience has consistently demonstrated that the implementation of advanced information systems and technologies cuts across many corporate institutional barriers. A learning process approach has proven to us that such barriers can be overcome to transform the customer’s organization into a truly learning one. Typical steps in approaching a project by DSI involves:

  1. Starting with high-level workshops at customer site
  2. Continuing with customer training at DSI and customer sites
  3. Involving customers in development of needs and requirements
  4. Involving customer in periodic reviews and improvements
  5. Involving customer in technical and informational visits
  6. Establishing a follow-up mechanism after project completion
