Verification means Testing the software  correctly 
implements the specific function in that phase.It performs 
each and every stage of SDLC.
Validation Means to ensure the software that satisfied 
customer's requirements

Verification: To ensure that the s/w correctly implements 
the specific function. 
Validation : To ensure that the s/w is satisfied the 
customer requiremens. 

Verification - Are we building the product Right?
its the process of determining whether or not the products
of    a given phase of software development fulfill the
requirements establised during the previous phase.

Validation- Are we building the Right Product?
Process of evaluating software at the end of its development
to ensure that it is free from failures & complies with the
requirements.

Verifiaction- is nothing but Testing
Validation is nothing but a part of Process(QA)

Verification is nothing but to check whether our 
application is based on corresponding specification or not?

Validation is nothing but to check whether our application 
functionality is equal to customer requirements  or not?

Verification is the process of determining if a system meets
the conditions set forth at the beginning, or during
previous activities of the software development life cycle,
correctly. These conditions are set forth in software
requirements, which are usually formally documented. The
standard for software requirements documentation is
ANSI/IEEE Standard 830. Verification typically involves
reviews and meetings to evaluate
documents,plans,code,requirements and specifications. This
can be done with checklists, issues lists, walkthroughs, and
inspection meetings.

Validation is the process of evaluating a system to
determine whether it satisfies the specified requirements
and meets customer needs. Validation typically involves
actual testing and takes place after verifications are completed

Validation
-----------
1) Am I building the right product
2) Determining if the system complies with the requirements 
and performs functions for which it is intended and meets 
the organization?s goals and user needs. It is traditional 
and is performed at the end of the project.
3) Am I accessing the right data (in terms of the data 
required to satisfy the requirement)
4) High level activity
5) Performed after a work product is produced against 
established criteria ensuring that the product integrates 
correctly into the environment
6) Determination of correctness of the final software 
product by a development project with respect to the user 
needs and requirements

Verification
------------
1) Am I building the product right
2) The review of interim work steps and interim 
deliverables during a project to ensure they are 
acceptable. To determine if the system is consistent, 
adheres to standards, uses reliable techniques and prudent 
practices, and performs the selected functions in the 
correct manner.
3) Am I accessing the data right (in the right place; in 
the right way).
4) Low level activity
5) Performed during development on key artifacts, like 
walkthroughs, reviews and inspections, mentor feedback, 
training, checklists and standards
6) Demonstration of consistency, completeness, and 
correctness of the software at each stage and between each 
stage of the development life cycle.

Verification is the process of doing reviews and 
walkthroughs and conducting interviews.
This is doing before coding phase.
Validation is the process of doing actual testing in the 
source code.
 This is always starting after coding in SDLC.

Testing includes verification and validation:
Verifcation: building the product right.
Validation: building the right product.

Hai
According to me
Verification :is nothing but static testing.
i.e we can check whether the s/w meet the customer 
specification r not.
this is done by dev team
EX.reviews,inspection.

Validation: is nothing but dynamical testing
i.e we can check whether the s/w meet the customer req r 
not.
This is done with the involvement of client
ex.Block box testing

Verification means the evelution of documents by reviews 
and meetings.Verification is Static Testing

Validation means the testing done by the tester. Validation 
is Dynamic testing

Verification is to check weather the system functionality 
is according to the SRS and FS but Validation is to check 
weather the system working according to SRS and FS.

Verification is are we building the right product? it is 
static testing. this is corrective method of software 
testing. This is informatl method of software testing. 
before coding, testing will happen. no code will be 
checked. here.

Ex:Walkthrogh, inspection,reviews, etc.

validation is have we done right product? it is dynamic 
tesing. this is preventive method of software testing. 
formal method of software testing.  after coding, 
validation will be done based on the requirement of the 
client.

Ex: Behavioral or functional testing using software. real 
testing.

verification is the the process confirming the software 
meets its specifications.
Validation means it is process confirming that software 
meets its user requirements

Verification: the process verify of the product,whether
meets design requirement or not.
Validation:the process validate of the product,whether meets
customer requirement or not.
