I worked for an ex-Australian Navy commander who managed various Asset and Maintenance groups for various organisations. The subject of maintenance is a very interesting subject.
If your maintenance regime is done properly, over the long haul, you save a fortune. Do your normal maintenance, refurbish at the correct times and replace with new when the % maintenance cost has reached the trigger point.
This means that every asset lasts longer (on the whole) costing you less and you get some return on that asset in the end. The one thing that generally gets in the way of proper maintenance are the accountants. They have a penchant for not understanding maintenance and future costs.
I have seen them willing to spend up to 80% of the cost of replacement for an item on repairing an item year on year, when it would be better to simply replace the item in question. They also seem to have the general attitude of "It's working therefore we do not need to spend any money on maintenance for it." This attitude seems to ensure that all sorts of organisations have a continually degrading asset base instead of a maintained asset base.
If you were to look at each state government in any country, you will find that most of the state assets are ill-maintained and that to get them to the correct maintenance level would be more than the current state budgets.
The other side of this is that accountants have a skewed point of view as to what is an asset and what is not. As such they will spend plenty of money on smaller item with replacement rather than refurbish or repair those items. Hence, office furniture, phones, computers, etc, are treated as consumable items and not worth repairing. So why would suppliers and manufacturers be bothered to make these items repairable?
Change the mindset of those whose responsibility is the finance and your will see a change in what supplier and manufacturers do in terms of repairability of their products. The small scale consumer such as us would then then benefit from this.
It effect, the mentality of not repairing items has a number of interconnected causes that feed the problem, from the basic tax law and attitudes of accountants "protecting" the bottom line, to companies using this attitude to make it cheaper to not design products that are repairable, to patent law and copyright law, to that simple staple called greed and the other stable called politics.
