What is Verification and different strategies of Verification - Reviews and Management Reviews

Verification is the process of evaluating a system or component to determine whether the products of a given development phase satisfy the conditions imposed at the start of that phase.
Verification process helps in detecting defects early and preventing their leakage downstream. Thus, the higher cost of later detection and re-work is eliminated.

The different strategies in Verification are:


A process or meeting during which a work product or set of work products is presented to project personnel, managers, users, customers, or other interested parties for comment or approval. The main goal of reviews is to find defects. reviews are a good compliment for testing to help assure quality. Few purposes of SQA reviews are assuring the quality of deliverable's before the project moves to the next stage. Once a deliverable has been reviewed, revised as required, and approved, it can be used as a basis for the next stage in the life cycle.
Types of reviews include management reviews, technical reviews, inspections, walk-through and audit.

- Management Reviews :
These reviews are performed by those directly responsible for the system in order to monitor progress, determine status of plans and schedules, confirm requirements and their system allocation. The main objectives of management reviews are:
* Validate from a management perspective that the project is making progress according to the project plan.
* Ensure that the deliverables are ready for management attention.
* Resolve issues that require management attention.
* Identify any project bottlenecks.
* Keeping the project in control.
Support decisions are made during such reviews include corrective actions i.e. changes in the allocation of resources or changes to the scope of the project.
In management reviews, audit reports, contingency plans, installation plans, risk management plans, software q/a are reviewed.
The participants of the review play the roles of decision maker, review laeder, recorder, management staff and technical staff.
