Introduction

Increase project-based IS development outsourcing




Outsourcing provides a wide range of specialized skills /
complexity
Packages tailored to the particular business
Alleviate staffing difficulties and skill shortages
E-monitoring of (outsourced) development tasks


Monitoring agents communicate through Web services
Alert Management System (AMS) mechanism




control rules
dependency and discrepancy handling
Achieve overall central administration and project management
Financial institutions: monitored by regulatory authorities


Securities and Futures Commission (SFC) (HK)
Mandatory Provident Fund Authority (MPFA) (HK)

How “control rule” works
2. An alert task is generated
in the central AMS for
follow-up.

Monitoring Agent






Thread pool implementation in JSDK 1.5
Issue HTTP/HTTPS GET and POST request
Send HTTP variable and value together with
HTTP/HTTPS POST request
Simulate user request by issuing a list of predefined
HTTP request together with HTTP variable and value
Memorize and handle HTTP session of various
language (e.g., with sites written in Java, session
information will be identified by a cookies named
JSESSIONID)
Web services invocations / SOAP messages sent over
HTTP protocol

Alert Processing




Submit alerts by means of Web services requests to
the AMS.
Condition Definition module specifies when an alert is
triggered in a task.
Target Matching step is responsible for identifying the
parties to which the alert will be forwarded.
Follow-up Actions are the handlers to be executed
after an alert.

Conclusion

Alert Monitoring mechanism handles




Web service technology allows the monitoring on a
global standardized platform


supervising of the development process of software modules
communications of parties / personnel involved
overall progress monitoring
Integration with other tools for monitoring project schedules,
such as, MS Project, Lotus Notes
Strengthens the monitoring ability in both coverage
and depth

Future Work






Monitoring complex system development (e.g., spiral
model)
Inter-dependencies of alerts and cascaded exceptions
Both internal / outsourcing support
Software reliability monitoring
Use questionnaires to evaluate the satisfaction of
various stakeholders
Security and privacy issues
