Introduction:
 What is a "Bug” (read: “Computer/ Software Bug”) ?
 Wikipedia offers a good literature:
• A computer bug is any problem with a computer, whether caused by
software or hardware. (source:
http://en.wikipedia.org/wiki/Computer_bug)
• Bug (software bug) - an error, flaw, mistake, "undocumented feature",
failure, or fault in a computer program that prevents it from behaving as
intended (e.g., producing an incorrect result). (source: “A study
concerning the bug tracking applications “ – Journal – Prof. Dr.
Christian Bac – Telecom Sudparis)
 A few of popular understanding:
• Bug Tracking - the process of reporting and tracking the progress of
bugs from discovery through to resolution. (source: “A study concerning
the bug tracking applications “ – Journal – Prof. Dr. Christian Bac –
Telecom Sudparis)
• Bug Tracking System - a software application that is designed to help
quality assurance and programmers keep track of reported software
bugs in their work (source: http://www.bugzilla.org/docs/)
 What is a “Bug Tracking” ?

Introduction:
• Lesson Learned
Base on team experiences from a real project on PMU Automotive Division during after mid year 2012,
below the following fact were found by team on the last project:
• Found limitations “to gather bugs” and “to assign resources” for fixing them, because PM had to
wait ”to make sure” the item of issue
• Found difficulties “to manage bug report” (Reproduce/ simplify/ generalize/ analyze)
• Found difficulties “to track back of bugs history”
• Bug Communication
“Bug Tracking” is not only to keep track of issue or problem to reports and
maintain feature requests (if any changes) , but also to coordinate work
among developers team, management & customers
 General Consideration Regarding “Bug Tracking”

Bug Tracking Tool: (Cont…)
“If you’re going to write software of any size, you're going to have a few bugs along the way, and you’ll
need to keep track of them somehow. If you’re going to track your bugs, you may as well do it right. ” –
(source: http://www.bugtracker.com/bug-tracking-guide-best-practices)
Here are some benefit to use Bug Tracking:
•Increase visibility of development process
•Traceability of bugs and their resolutions
•Release planning
•Resource scheduling
•Prioritization
•Improved control of a project
•Information consolidation
•Improve the quality of your software by increasing productivity
•Raise customer satisfaction

• Designing workflow or framework
An workflow is a diagram that describes the states of the bug or defect from it is created to it is closed.
The first issue deals with the question: How workflow to design with standard framework?

• Meaning Fields
The second issue deals with the following questions:
• Which component does this bug fit in ?
• What does a "critical" priority mean ?
• etc. (undefined)
Also, there must be provided descriptions of each component, and a default owner for each component
• One Bug Many Releases
A very important characteristic of a bug tracking is the methods used
in order to track the same bug in different releases

• Trusting History
Many interesting pieces of project information are time-based. For example:
• The minimum time necessary to find a bug
• The time necessary to fix a bug
• The estimative number of bugs delivered with a specific release

Comment & Opinion:
“The most important info that
reporter can provide is a way to
reliably reproduce the issue”

Bug tracking is a fundamental part of the Software Engineering
lifecycle process. Effective use of a bug tracking system will lead to a
more structured approach throughout the development lifecycle,
resulting in a higher quality product while also reducing development
and support costs.
