Walkthrough :A walkthrough is a set of procedures and 
techniques designed for a peer group, lead by the author to

informal type of review. The walkthrough takes the form a

Reviews are of 3 types

1) Technical Review: A Technical Review (also known as a 
peer review), is considered to be a formal review type, 
even though no Managers are expected to attend.  It 
involves a structured encounter, in which a peer/s analyse 
the work with a view to improve the quality of the original 
work.

1	Ideally led by the Moderator
2	Attended by peers / technical experts
3	Documentation is required
4	No Management presence
5	Decision making
6	Solving technical problems

2) Inspection Review: An inspection is a formal type of 
review. It requires preparation on the part the review team 
members before the inspection meeting takes place. A follow-
up stage is also a requirement of the inspection. This 
ensures that any re-working is carried out correctly.


1	Led by a Moderator

3	Metrics are included
4	Formal process
5	Entry and Exit Criteria
6	Defect finding

3) Informal Review: An informal review is an extremely 
popular choice early on in the development lifecycle of 
both software and documentation. The review is commonly 
performed by peer or someone with relevant experience, and 
should be informal and brief.


1	Low cost
2	No formal process

4	Widely used review

Review: Once the Test cases are created, it will be given 
for the review to the peers of the project. This process is 
in existence for test case creation and execution since 
every one’s perspective of writing test cases and finding 
defects are not the same. 

Some organizations even have Peer Review 1 and Peer Review 
2 and the final review will be done by the Test Lead. The 
Test Lead Finalizes and gives assurance that the Review was 
done and nothing was missing from the requirement. The 
review happens for all the Iterations, Change Request and 
Enhancements.

Walkthrough is a common term used during the informal 
meeting. In every project many walkthrough will happen to 
discuss about Business requirements, BCP plan, project 
evaluation along with managers etc. No pre-preparation is 
needed for this kind of meeting

 

Inspection is a formal meeting which is a pre-planned 
activity. The appointment is generated for this meeting. 
The Inspection may happen any time during the project 
phase. This may include the developers, testers, managers 
and even the client. The inspection is documented and 
circulated among the team members.
