The French repairability index – one year after its implementation [pdf]
The first repairabilty key is the standardization of parts, witch exists but only limited to VERY common parts, another is the availability of spare parts.But the real key is the fight against crap: you sell a mixer with a plastic gear, easy to speculate that will break after few year, ok, you are allowed to do so, but you get a progressive tax: as much as durable and repairable is your device you pay less. For a mixer that means: 30% of the sale price as tax if it's expected lifetime is less than 10 years of normal usage.Another fraud is "spare parts available ONLY to 'certified technicians'" witch means repair is as expensive a get a new gear.Personally, for standards:- anything "commodity like" must be made of standard parts for anything critical to it's functionality, that means a washing machine must have a water pump with flexible connection and standard threads / diameters and fixing that you do not need an original one but any "common pump" can be found, whiskers with standard whips inserts etc;- all spare parts on sale from the company website, at a reasonable price, witch means buying all cost no more than +10% of the assembled device on sale, no restriction on buyers, no need to be "certified" by the company etc. Spare parts MIGHT have a mark to avoid warranty issues but nothing else;- ALL software MUST BE open sourced, no restriction allowed, no bullshits on IP and so one, any black box can't be on sale in 5 years (to give time to adapt) and the code must be practically readable and usable by anyone;- anyone who can prove planned obsolescence, like technicians from inside the OEM, get rewarded SIGNIFICANTLY for their publication and the OEM so badly sanctioned that the whistleblower get no issue if is cut off some market, the company loose so much that no one want even try.
