2 OUTLINE TOPIK What is DSS? Why DSS? (for) Who is DSS?
Who does develop DSS? Where & when do we use DSS? How to develop DSS?

3 What is DSS Decision support systems (DSS) are a class of computerized information systems that support decision making activities. The concept of a decision support system is extremely broad and its definitions vary depending upon the author's point of view. As with the definition, there is no all-inclusive classifications of DSS either. At the user-level, passive, active, and cooperative DSS may be differentiated. At the conceptual level, differentiation may be made among communication-driven DSS, data-driven DSS, document-driven DSS, knowledge-driven DSS, and model-driven DSS.

4 What is DSS Once again, different authors identify different components in a DSS. Sprague and Carlson (1982) identify three fundamental components of DSS: the database management system (DBMS) the model-base management system (MBMS), the dialog generation and management system (DGMS). Definisi menurut Turban  lihat OHP

pemrosesan transaksi kendali operasional kendali manajerial perencanaan strategis Lihat piramida manajemen (OHP) Perubahan peran sistem informasi 1950an : teknis 1960an an : manajerial 1980an – 1990an : institusional Lihat gb 1.3 pada OHP

6 Who DSS utk manajer tingkat menengah ke atas  lihat piramida manajemen (OHP) Pembuat DSS bisa orang dalam organisasi atau orang luar (outsourcing) spt halnya SI yang lain

7 Where & When? Pada saat manajer perlu mengambil keputusan yang:
semi terstruktur ATAU tidak terstruktur Contoh: lihat gb 1.2 pada OHP

8 How? Hampir serupa dengan metodologi pengembangan SI pada umumnya
Lihat gb 7.1 & 7.3 pada OHP
