What is boundary value analysis (BVA)? What is the use of it?

Boundary Value Analysis(BVA) is a technique for test data selection. The test engineer chooses the values that lie along with the data extremes. It includes maximum, minimum, just inside, just outside, typical values, and error values. Boundary Value Analysis is a technique used for writing test cases. 

Please check the following example on the BVA technique: 

If a particular field accepts the values from 1 to 10000, then we test that field by entering only 1, 10000, 0, 10001, 9999, 2. i.e. we check on the boundaries and then Minimum-1, Minimum+1, and Maximum+1, Maximum-1.
