Articles tagged Reliability growth and management

The improvement in a reliability parameter caused by the successful correction of deficiencies in item design or manufacture. It entails the systematic planning for reliability achievement as a function of time and other resources and controlling the ongoing rate of achievement by reallocation of resources based on comparisons between planned and assessed reliability values.

Reliability Growth

Concepts, Strategy, Duane Model and Application Case Study

We are happy to release this video on Reliability Growth which is a very important strategy to assure reliability of new products. In this video, Hemant Urdhwareshe has explained the basic concepts and strategy of reliability growth, the related mathematical relationships, and the Duane Model with an application case study of introduction of new model of Diesel engine. Hemant is a Fellow of ASQ and is ASQ CRE, CMBB, CSSBB, CQE and CMQ/OE. We are sure that viewers will find it useful. If you like the video, do not forget to click the like button.

9 Reliability Growth Patterns for Two Test Phases

The basic idea of reliability growth is the information learned during testing allows the team to make improvements.

The improvements then reveal themselves in the next round of testing. There are improvements during each test phase as the immediate fixes occur.

Plus some improvements may have longer lead times and be implemented in time for the next round of testing. [Read more…]

Duane Plot of Cumulative Failures Over Time

Let’s take a graphical view of reliability improvement that occurs during product development or improvement projects.

If we are making improvements the system reliability should increase. We can use the build, test, fix approach to measure improvements, find failures, design improvements, and repeat. [Read more…]

Reliability Growth Testing

One approach for reliability improvement is to find the weaknesses or faults, then fix them.

This is best done before shipping to the customer.

You may hear this called the Test, Analyze, and Fix Method (TAAF). Or, you may have heard of it called a Reliability Growth Test program (RGT). Either way, the essence is evaluating prototypes to find specific faults. [Read more…]
