3. Biography of Bertalanffy

   • • Bertalanfyy expressed thah real system are exposed to, and work together with, their environments and can obtain qualitatively new properties through development resulting in constant development
   • • The same concept and principles of organizations underlie different disciplines provifing a basis for their unification
   • • System concept include
     • o System-environment boundary

     • o State
     • o Hierarchy
     • o Gail directedness
     • o Information

6. How is GST relevant to us?

   • • As mentioned before the general system theory encompasses all disciplines that utilize systems
   • • As time and technology has evolved, there has been great emphasis on information systems
   • • Many organizations such as IBM and Texas Instruments rely on this theory to help their business run efficiently

7. Information system

   • • System consisting of the networks of all communication channels used within an organization
