One of my friend is working as QA Consultant (Software Testing Engineer).How Six Sigma is beneficial for him and for his Company? His 2 main concerns are:

1. What would be his approach(after getting Green Belt certified) while testing the application?

2. How will he be responsible for improving the processes in his company?

Software testing mainly includes the following -

• A testing plan of the actual testing tasks that will need to be execute to carry out the test strategy.
  

• Test cases that have been prepared in advance in the form of detailed examples you will use to check that the software will actually meet its requirements
  

• Test data consisting of both input test data and database test data to use while you are executing your test cases
  

• A test environment which you will use to carry out your testing
  

• A test strategy that indicates what types of testing and the amount of testing that will work best at finding the defects lurking in the software.If your involvement is only with the last two, you may be using some of the quantitative techniques, but if you wish to be involved with the first three, you shall need most of the remaining as well.
  

Examples

• You can use hypothesis testing to analyze data related to tests. You need to use regressions, ANOVA, t tests, chi-quare tests and the like.
  

• You may use hypothesis testing to compare different testing programs or solutions or platforms and reach the right conclusion using statistics.Hypothesis testing is useful in simulated tests as well.
  

• You can compare performance of testing engineers or teams over time to verify whether their performance has improved over time.
  

• You can monitor performance using control charts.
  

• You can use a Six Sigma tool called DOE for creation of the right test cases that can reduce your testing time.
  

Green Belt program shall have high utility for you if you wish to build up your analytical abilities and wish to move up the ladder.

Hi Hemant

                 Please explain or a link(Web), How DOE can be used in testcase creation

 

Hello Firoz, 

Orthogonal Arrays that make us use of experimental design (DOE) concepts can be used for this purpose. 

Please have a look at http://learnsoftwareprocesses.com/2007/08/21/orthogonal-array-testing-strategy-oats/
