Suppose after completion of an application or module, if another module is to be added, then we need to test the new module as well as the impacted area which is affected by adding a new module.

Impact Analysis will be done to find the impact area of the application by adding a new module. Generally team lead will take the initiate for this.

Team lead will send a mail to client asking for the impact area (if developer is new to domain), also send a mail to development team and testing team asking for the impacted area. After getting the response of all three, team lead will do the consolidated report of all the mails. This consolidated mail will be given to the Test Engineer saying this is the Impact Analysis Report and these are the impact areas.

RE: Impact Analysis

Impact analysis is required when :

1. Testing after Bug fixing
2. Application is Upgraded
3. New module is added

All the cases better to discuss with developer for detail Impact analysis. If developer is not available then check th edesign doc and funcional diagram for data flow and find the dependency with fixed or added modules. All the modukes are depended on the fixed/Added module are under the possible impact area.

RE: Impact Analysis

Impact analysis- analysis to test toughness of a material ie. its ability to absorb energy during plastic deformation. Tougness takes into account both strength and ductility factor. Impact strengths are generally lower than strengths achieved under slow loading. For testing impact strengths we have 2 basic tests- 1. Izod test 2. Charpy test

Izod test- It consists of testing toughness of a material keeping it fixed and making a notch in it and striking it with the hammer...the impact is ;read by a pivoted device.refer to web for diagrams.

Charpy test- similar to izod test except that here the job is simply supported. rest everything is same.
refer to figure for the difference instron.in/wa/products/impact/images/charpyIzod . gif
