WISARDS - Wintec's Applied Research in Data Science


Welcome to the Applied Data Science Research Group.
We integrate existing tools and algorithms in a simple-to-use process so companies can easily get value from their data.
We offer services for you to solve problems or improve business performance, through the analysis of data. 


What we offer

Services on offer include (but are not limited to) consulting about how to use data for improving business process performance. Improvement could be achieved by using any type of data-related approach, such as Process Mining or Six Sigma. 

Process mining is a family of techniques in the field of process management that support the analysis of business processes based on event logs. During process mining, specialized data mining algorithms are applied to event log data in order to identify trends, patterns and details contained in event logs recorded by an information system. Process mining aims to improve process efficiency and understanding of processes. Process mining is also known as Automated Business Process Discovery (ABPD).

Six Sigma (6σ) is a set of techniques and tools for process improvement. A six sigma process is one in which 99.99966% of all opportunities to produce some feature of a part are statistically expected to be free of defects. Six Sigma strategies seek to improve the quality of the output of a process by identifying and removing the causes of defects and minimizing variability in manufacturing and business processes.
