6. Data Mining By GSL
• We use “Data mining techniques in order to discover patterns
in large data sets involving methods at the intersection of
artificial intelligence, machine learning, statistics, and
database systems.
• We examine large databases to produce new information. We
do the following:
– We use statistical methods and artificial intelligence to
analyze data.
– We try to find hidden features of the data that were not
yet known.

7. 5 Tasks of Data Mining by GSL
• Classification – Categorizing data into actionable
groups. (ex. loan applicants)
• Estimation – Response rates, probabilities of
responses.
• Prediction – Predicting customer behavior.
• Affinity Grouping – What items or services are
customers likely to purchase together?
• Description – Finding interesting patterns.

8. Identifying Information Gap by GSL
• The shortfall between gathering information
and using it for decision making.
– Do firms have inadequate data warehouses?
– Business Analysts spend 2 days a week gathering
and formatting data, instead of performing
analysis. (Data Warehousing Institute).
– Business Intelligence (BI) seeks to bridge the
information gap.

9. Data Warehouse
• Collection of data
from multiple
sources (internal
and external)
• Summary, historical and raw data from operations.
• Data “cleaning” before use.
• Stored independently from
operational data.
• Broken down into DataMarts for
use.

11. Strategic Controlling by GSL
Strategic controlling strengthens the corporate
strategy
Our management consultancy controlling advises medium-sized businesses in introducing
and implementing their strategic controlling. On the one hand, strategic controlling shall
check the corporate strategy and the strategic marketing regarding the target achievement
and on the other hand, the strategic controlling establishes a basis for the strategic corporate
planning by means of a competition analysis.
Strategic controlling improves the financial figures
prematurely
We support medium-sized businesses in assessing and establishing strategic business areas,
identify divergences in the strategic objectives and initiate counteractions by means of
strategic controlling before the divergences are reflected in the operational figures. Strategic
controlling can improve the company’s livelihood sustainably.
