A product's reliability is influenced by multiple factors throughout its entire life cycle, beginning from the conception of the product to its eventual disposal. During the design phase, decisions regarding materials, components, and processes significantly affect reliability. For instance, choosing high-quality materials and robust design techniques can improve the product's durability and performance.

As the product moves into the development and manufacturing phases, the processes used can introduce variations and defects that might compromise reliability. Quality control measures and adherence to specifications during manufacturing play a crucial role in ensuring that the product performs reliably.

Once the product is in use, maintenance becomes a critical factor; however, it is just one component of a broader set of influences. The operating environment, user practices, and the frequency and quality of maintenance can all affect the product's reliability over time.

Finally, when considering end-of-life, proper disposal and recycling methods can also contribute to the overall impact on reliability. Each phase interacts with others, establishing a comprehensive framework that ensures or diminishes reliability across the entire life cycle of the product. This holistic view emphasizes that reliability does not solely come from one phase but is a cumulative result of decisions made throughout all stages of a product's life.
