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.
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
Why DSS • Ada banyak tingkatan dan peran manajemen dalam organisasi: • pemrosesan transaksi • kendali operasional • kendali manajerial • perencanaan strategis • Lihat piramida manajemen (OHP) • Perubahan peran sistem informasi • 1950 an : teknis • 1960 an - 1970 an : manajerial • 1980 an – 1990 an : institusional • Lihat gb 1. 3 pada OHP
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
Where & When? • Pada saat manajer perlu mengambil keputusan yang: • semi terstruktur ATAU • tidak terstruktur • Contoh: lihat gb 1. 2 pada OHP
How? • Hampir serupa dengan metodologi pengembangan SI pada umumnya • Lihat gb 7. 1 & 7. 3 pada OHP
