    How can we quantify durability?

    Is it a bit confusing? The device you are using to read this post may be a couple of years old and you are thinking that it will run like this for some more time. You are not wrong and many of us do think in that way. Now, let's think of the home appliances we use daily. Some of them might be perfectly working without being repaired after the purchase and if you are asked to refer someone to a specific brand of appliance that is quite durable I am sure you will refer to the brand that is providing uninterrupted service without being repaired. You call that brand or specific model durable. The experience may vary from person to person as the other person may find the same model not so durable.

    Now the interesting thing is how you are going to define durability. Is it all about the number of years it provides uninterrupted service or the period predetermined by yourself crossing which you will call it durable? For example, nowadays a mobile phone generally lasts for two to two and half years and a person will be quite satisfied if it gives uninterrupted service up to that time. The device can work well even beyond that period if it is used but if the person discards the device after that period I hope the person will rate the product as a durable one since his perception of the durability of a mobile device is two and a half years. But if a person expects that a new mobile phone will work for five years and if it starts giving trouble just after three years she/he will not consider the product durable. I have heard many commenting on hearing the passing away of an aged person by saying "he has lived enough and how long you can expect?" Again, it varies from person to person as the person making such a comment thinks that the aged person has crossed the durability while others may think the person could have lived for some more time as the person was otherwise fit, though aged.

    From these examples, it may be said that the threshold of durability can vary from person to person.

    I agree with the author, Durability is a relative word. My expectation is less and the device worked for more than m,y expectation. That means the product is durable as far as I am concerned. Some people may have higher expectations and the product may not perform to their expectations. That means the product is not durable. Durability is a quality parameter. Again Quality is also a relative word. The product that I feel is a quality product may not be liked by the other person.

    The durability of a human being may differ from person to person. Some may live for 100 years and some may die at 20 years. The average expectancy these days is around 63 years. Once you cross 63 years, you can say you are durable.

    The thinking process, the cost of the product, and the quality of the product will generally decide the durability of the product.

    Manufacturers generally give a figure of durability for their products based on the sample testing of their items in laboratory conditions. They will generally tell that the item is guaranteed for 3 years or whatever they offer and will be able to work for a total of say 10 years if it is handled properly and not damaged by the user. That is, of course, a very general statement and from user to user, the duration of use of a gazette or an item will solely depend on how one maintains it and how one handles it.

    At the same time out of a particular lot of items, some items may be defective. They are generally removed during quality testing still a percentage remains in the lot like that. These pieces will start giving trouble within a few months of buying while other pieces from the same lot will be working for longer. So many people prefer to buy things from high-quality manufacturers where this thing of getting an items bad in no time can be avoided.

    Knowledge is power.

    If we purchase some items from some reputed firm, we get the exact details of the said component including its durability. Depending upon the product, we do have our own idea regarding the durability of the item. If the age of the product exceeds beyond our expectations, the product can be defined as more lasting and durable, But not fulfilling that expectation parameter is indicative of its poor quality.

    However, the product being offered by the manufacturers roughly offers the age of its durability. Normally it lasts more as indicated in the booklet. This is applicable to fridges, washing machines, TV etc where we find that the life of the product is far far more than their declarations in the accompanying booklets. Life - span of the same product might not be of considerable duration if purchased with lesser known company.
