Reliability engineering has both quantitative and qualitative aspects;
measurements of reliability are necessary for customer
requirements compliance. However measuring reliability does not
make a product reliable, only by designing in reliability can a product
achieve its reliability targets. items are designed for a specific operating environment and if they are then used this environment then failure can occur ​

Answer 1

Answer:

While it can be frustrating to deal with at the time, resolving failures and getting to a defect free launch is one of the most satisfying parts of product development. Understanding how to detect failures, where to look for them, and common failure analysis methods can add structure to your workflows can reduce the number of mistakes in your program improving your product’s chance of launching on time and on budget.

Because it is so hard to know where to start, Instrumental’s team of product design engineers has written this 3-part series to help you. In Part 1 below, we will discuss tools you can use to identify common sources of problems and ways you can reduce issues in the first place. Part 2 will dive deep into common failure analysis processes and techniques and Part 3 will introduce you to some key questions to ask during failure analysis.

Nobody wants to deal with failures, but it’s best to be prepared when they happen. We continue to be advocates of prevention as the best way to reduce problems, so it helps to be organized and vigilant from the beginning in recording as much information as possible about the design. Document how your product moves through the supply chain and the assembly line and how failures were induced and identified. The more good sources of information you have, the better equipped your team will be to tackle failures that will inevitably occur.

Key Takeaways

Create documentation and test criteria to detect issues in your development builds especially those that occur at critical junctions

Critical junctions in your development occur at any process step that changes the form or function of the product or could expose the device to damage.

Many silly mistakes can be mitigated through improved processes and checklists.

Make sure to refine your development processes based on past experiences.
