Lesson 1 Study Journal

This course is about how to structure a business idea, use model to simplify relationship in cooperation. We usually draw picture to detail the design. By using picture, we can discuss issues occurred in practicing an idea, let people know how a company works.
There are two things I do not understand in Learning Guide. Some references behind each lesson do not include a chapter or page. Whether I have to read the whole book, or just pick up a related part to read? Another thing is I can not find one book (Norman, D. A, 1995) in Swinburne library, and this book is referred by many lessons. It is an important book, but where can I find it?

Some concepts explain below:

Model. A prototype or surrogate of a complex situation. It can be a physical model, such as an architectural model of urban design, or a mathematical model of interactions of many variables. It is used in simulations for relating various components together or can be a stand alone tool to evaluate different approaches using different assumptions. Recent use of personal computer tools allows many types of software to effectively answer questions such as "what if I increase the growth rate"; these too are models.

System development life cycle (SDLC). In this cycle, systems are developed, used, modified, redeveloped, used, modified, and so forth. Many systems in use today have been through this process dozens of times and are, tracing back through all their versions, 25 or 30 years old.
