Information and Knowledge Management using ArcGIS ModelBuilder

Misoo Kwon
Information fidelity: This indicator is for reviewing whether the data can satisfy user requirements
and measures quantitative sufficiency of information, diversity of information and substitutability
for existing resources.
Utilization convenience: This indicator reviews whether a user can easily use wanted data and
measures convenience of database use and search speed.
Utilization rate: This indicator reviews the performance of database use such as the number of
visits, searches and downloads.
Utilization efficiency:This indicator is for reviewing whether the provided data increased business
efficiency of user in terms of the amount of time saved.
System management status: This indicator is for reviewing whether the database system is
maintaining its optimized operation level. In particular, it reviews whether database management
system monitoring is performed and checks the number of times that data were tuned.
System processing speed: This indicator reviews whether the response time and throughput
satisfy transaction requirements of each business process. In detail, it reviews the average
response time of database and throughput.
Data integrity: This indicator reviews if there are any data missing from required processes for
business support. Specifically, it reviews the ratio of business and logical null values.
Data accuracy: This indicator reviews whether the patterns and codes of data in the database are
accurate. Specifically, it measures the ratio of data threshold compliance, ratio of pattern
accuracy and ratio of code accuracy.
Data consistency: This indicator reviews whether there is any inconsistency between the same
data within the database.
2.3 Performance review time and reviewer
Performance review of NDP is one that is carried out during the second half of every year on the
project result of the previous year. The reason for reviewing the performance afterwards is to
measure the outcomes and impact of investment, find any problems in project operationas well as
ways to improve them, and further improve performance.
Performance review is carried out by selected survey agencies under the management of National
Information Society Agency, which is the main organization supporting the project. The result of
performance review is reported to the Ministry of Public Administration and Security and is used for
selecting the next year NDP.
3. Result of performance review in 2010
3.1 Overview
In 2010, the performance review was carried out on 50 databases that were established in 2009
mainly in terms of business performance (user satisfaction, system utilization, system performance
and data assurance) and economic impact.
The review target was database users, system managers operating and managing developed
databases, while the target for data assurance review was the entire databases developed during
2009. Database users included internal users who use the developed database for business
processes within their organization, relevant users who utilize the database from outside and the
general citizens.
Tools that were used for review were a survey questionnaire, checklist and survey tool for each
performance review category as described above and face-to-face interview and online survey were
the methods of review. From users, user satisfaction and convenience were the two categories
surveyed through face-to-face interviews and online surveys (on a five-point scale). From system
managers, system performance, utilization rate and time-saving were surveyed using a survey
checklist. As for reviewing data assurance, a survey tool was used.
Reviewing data assurance is to inspect any error in data values of the database. During the process,
an automation tool is used based on standard information and business codes as defined in columns.
