Business Intelligence System Case Study

English (2005) defined BI "quality information in well-designed data stores coupled with business friendly software tool that provide knowledge workers timely access, effective analysis and intuitive presentation of the right information, enabling them to take right actions or make decisions".

White (2005) it defined BIS as information systems that provide information and improve its quality that supports decision making and achieves business goals. It divided BIS into two parts: 1) data warehouse 2) access to data, data analysis and reporting.

KalKaota &Robinson, (1999) business intelligence systems infrastructure components that support the quality of decision making:

1. Key information technology related to store data (Extraction, transforming

They found that BIS influence IQ its content and access and generate business value through improving business processes and decision making (that depends on the quality of information, appropriate organization culture and structure of development and decision making management).

Olszak and Ziemba (2006),”Business Intelligence Systems in the Holistic Infrastructure Development Supporting Decision-Making in Organizations” study the impact of BIS on quality of decision making. The study focus on three components of business intelligence systems

1. Potential information technology (OLAP (online analytical processing) and data mining).

2. Key information technology (Extraction, transforming and loading (ETL) and data warehouse is a software used to store detailed data (level of production and sales) and Meta data (data about data) in specific period of time and location).

3. Business intelligence applications that include: insurance, banking, finance and telecommunications improve decision

Wieder and Ossimitz (2015), "The Impact of Business Intelligence on The Quality of Decision Making- A Mediation Model", the study talking about the growth of business intelligence and its effect on managerial decision quality took into consideration a mediation effect of Data Quality and Information Quality that resulting from BI, that support and improve the quality of decision by reducing uncertainty of decision alternatives and improving information.

They pay attention to BI management that consist resources of designing, alignment and development. And information quality (correctness, trusted, accuracy and consistency) affect decision quality that affected by a lot of factors: timeliness, speed, effectiveness, informed decision, accuracy, and correctness of decision making. And they took BI solution scope as a mediating variable that affects the relationship between BI and Decision making that contains BI functionality scope that is BI software products such as spreadsheet that improves and supports information, and infrastructure of planning and analyzing. They found that high BI solution leads to high decision making
