In this video, viewers will understand the basic concepts of Product Life Cycle. Phases of Product Life Cycle are Early Life period, Burn-in period or Infant Mortality period, Constant Hazard Rate Period and Wear-out period. Viewers will also get some understanding of the causes of failures in these phases.

In my previous article we covered the advantages of a phase and gate structure for new product development. Now we can discuss some proposed phase names for a new product development or product life cycle (PLC) process.
An organization may have an existing PLC process ‘baked-in’ to their culture and process documentation. Accordingly, there’s a wide range of PLC phase names, all of which are likely acceptable and based on solid reasoning.
Does your team procure, setup and put into operation equipment with a single focus on reducing the initial capital expenditure?
Do you work with your equipment suppliers to fully specify the equipment’s functions, performance, and reliability? Maybe not the reliability? [Read more…]
Often time’s equipment is procured, setup and put into operation with a single focus on reducing the initial capital expenditure. This can be a fatal mistake as the reliability of the equipment is built into the design of the equipment. This called the inherent reliability. Once the equipment is designed and installed, there is little the maintenance department can do to improve the inherent reliability. [Read more…]
The software element of products continues to grow.
Likewise, the number of field failures due to software issues continues to grow. Writing code is relatively straight forward, and some may even say it’s fun.
The process of debugging, or finding and fixing software defects, is not fun. [Read more…]
Each organization creates their own version of a product life cycle.
Often there are phase gate reviews that signal a transition from one phase to the next. In general, each set of phases follows a common progression from idea to retirement.
There are many references that include a description of the life cycle phases, so let’s explore two of them. [Read more…]
The purchase price of a product may be the start of the cost of ownership.
Maintenance and repairs may cost many times the initial purchase price. An efficient maintenance process and low-cost spare parts may help minimize cost, yet a design that optimizes the total cost of ownership is the most effective method. [Read more…]
