Change Management:
------------------
-> Managing changes is a process.The process is the primary 
responsibility of the software development staff.
-> The testers need to know two aspects of change
 1) The characteristics of the change so that modification 
of the test plan and test data can be made to assure the 
right functionality and strucuture are tested.
 2) The version in which that change will be implemented.

Configuration Mgt:
------------------
-> It is key component of the infrastrucutre for any 
software development organizations.
-> Set of activities designed to control by identifying the 
work products that are likely to change,establishing 
relationships among them,defining mechanisms for managing 
different versions of these work products,controlling the 
changes imposed and auditing and reporting on the changes 
made.

Version Control:
----------------
-> Once dynamic testing begins,the project team must ensure 
that the appropirate versions of the software components 
are being tested.
-> The configuration manager must develop both migration 
and back out procedures to support this process.

Defect Tracking:
----------------
-> It is used for tracking the defects or bugs arised.
