Validating business requirements
Verification of machinery and equipment usually consists of design qualification (DQ), installation qualification (IQ), operational qualification (OQ), and performance qualification (PQ).
DQ may be performed by a vendor or by the user, by confirming through review and testing that the equipment meets the written acquisition specification.
Qualification of machinery/equipment is venue dependent, in particular items that are shock sensitive and require balancing or calibration, and re-qualification needs to be conducted once the objects are relocated.
The full scales of some equipment qualifications are even time dependent as consumables are used up (i.e.
This can happen when, say, a product is built as per the specifications but the specifications themselves fail to address the user's needs.
Being totally aware of the fact that, when it comes to software requirements, changes are very common, we provide preemptive management of ongoing scope variability.
To avoide or minimize the uncontrolled changes, we tend to properly define, control and document all the components of project scope and to ensure transparent and efficient communication to eliminate eventual misunderstanding.
These are critical components of a quality management system such as ISO 9000.
The words "verification" and "validation" are sometimes preceded with "independent", indicating that the verification and validation is to be performed by a disinterested third party.filters) or springs stretch out, requiring recalibration, and hence re-certification is necessary when a specified due time lapse.
