Identifying nonconformity root causes using applied knowledge discovery

Identifying Root Causes of Web Performance Degradation Using Changepoint Analysis

The large scale of the Internet has offered unique economic opportunities, that in turn introduce overwhelming challenges for development and operations to provide reliable and fast services in order to meet the high demands on the performance of online services. In this paper, we investigate how performance engineers can identify three different classes of externally-visible performance proble...

Knowledge Discovery Using Heuristics

Uninformed or blind search, which processes and evaluates all nodes of a search space in the worst case, is not realistic for extracting knowledge from large data sets because of time constraints that are closely related to the dimension of the data. Generally, the search space increases exponentially with problem size, thereby limiting the size of problems that can realistically be solved usin...

Knowledge Management Project Abandonment: An Exploratory Examination of Root Causes

This paper examines the root causes of Knowledge Management (KM) project abandonment. The authors use root cause analysis to identify the causes of KM project abandonment in five well-documented cases of KM drawn from the literature. The findings are synthesized into a Cause-Effect Diagram (CED), culminating in a causal model of KM project abandonment. The model identifies three major categorie...
