Knowledge management system improvement towards service desk of IT outsourcing in banking business
Abstract:
In business, knowledge is an organizational asset that enables corporations to sustain
competitive advantages. In addition to increasing the demands of IT outsourcing to
deliver world-class services, the Information Technology Infrastructure Library
(ITIL) is a key concept to provide the high quality service, and the IT service desk is a
crucial function for a whole concept of IT service management.
Three current problems include 1) technical staff turnover is very high; 2) more
than sixty percent of all resolving time is spent to resolve the repeat incidents; and 3)
the assigned resolver group to deal with the incident may be inaccurate due to human
error. Thus, this thesis proposes a framework for a knowledge management system
with root cause analysis so, called KMRCA IT service desk system and evaluates its
performance. The system is composed of two main functions, a searching knowledge
function, and an automatic assignment function. This thesis evaluated the performance
of the searching knowledge function using a simulation study and concluded that the
system could significantly reduce time in resolving incidents. Moreover, my thesis
enhances the framework to select the most suitable resolver group to deal with the
incident using Text mining discovery methods. The ID3 decision tress method could
increase productivity and decrease reassignment turnaround times. Furthermore, the
rules resulting from the rule generation from the decision tree could be properly kept
in a knowledge database in order to support and assist with future assignments.
