LEARNING OBJECTIVES • Understand the basic concepts of systems development • Describe the four phases of the (PADI) system development life cycle: planning, analysis,

development, and implementation • Understand prototyping and throwaway prototyping and why DSS are typically developed

using these methods • Describe the factors that lead to DSS success or failure • Discuss the importance of project management and the necessary skills of a good project

manager • Describe the three technology levels of DSS: DSS primary tools, DSS integrated tools (gen-

erators), and specific DSS • Understand the learning process that occurs during DSS development

Up until now, we have presented the basic concepts and components of decision- making and decision support. Now we must learn how to implementa decision support system: U n f o r t u n a t e l y , a c q u i r i n g a D S S is n o t as s i m p l e as o b t a i n i n g p r o d u c t i v i t y s o f t - w a r e like a w o r d p r o c e s s o r .
