A critical design review (CDR) is an assessment of the product or system design's maturity, ensuring that it meets the specified requirements and is ready to proceed to the next development stage. It evaluates design performance, reliability, and readiness for production.

Bilateral tolerance means that the allowable deviation is specified in both directions from the nominal dimension.

In the provided drawing, the hole dimension is given with an equal tolerance range on both sides, indicating bilateral tolerance.

References: "Engineering Drawing and Design" by David A. Madsen and "Geometric Dimensioning and Tolerancing" by Alex Krulikowski discuss bilateral tolerances and theirrepresentation in technical drawings.

Destructive test methods are those that cause damage or permanent alteration to the specimen being tested.

Radiography:

Non-destructive method using X-rays or gamma rays to view the internal structure.

Acoustic Emission:

Non-destructive technique detecting transient elastic waves produced by a sudden redistribution of stress.

Corrosion:

Destructive process where materials are degraded due to chemical reactions with their environment.

Magnetic Particle:

Non-destructive method using magnetic fields to detect surface and near-surface discontinuities.

Corrosion testing inherently destroys or alters the material being tested, categorizing it as a destructive method.

The Process Decision Program Chart (PDPC) is a tool used to anticipate potential problems that could interfere with project implementation and to develop countermeasures to prevent or mitigate those problems. It is a structured method for mapping out every conceivable event and contingency that can occur in the course of a project, thus allowing project managers to plan for and avoid disruptions effectively.References:
