I often read many posts from members expressing their disappointment and often disbelief in the difficulties they have experienced in obtaining spare parts. Being fortunate enough to have a new van I have yet to be on the receiving end, but know full well that my time will come ...

As a consumer, I am not defending any manufacturer, however, after reading through this thread, I would like to add my contribution to the discussion from the perspective of someone in a relatively senior position for a company whose core business is the manufacture, supply and support of specialist industrial machinery. My comments are not in any way relating to any particular manufacturer, or even to caravans, but to the manufacture, assembly and supply of big ticket items in todays competitive market.

Whilst there are no doubt exceptions, today, in general the vast majority of manufacturing processes operate on the JIT model. When a manufacturers portfolio consists of a variety of different products or models that share the same platform but whose components differ, this is the only proven way to remain competitive.

As prof correctly points out, holding spares is a very expensive practice. Despite the average consumer expecting that the manufacturer or supplier of their favourite luxury product, whatever it may be, holds enormous quantities of every part on the shelf, the reality is that this is such an expensive practice, those responsible for the operational side of most medium to large manufacturing organisations are usually penalised for holding stock. You may well ask why this would be ? - Surely In the interest of good customer service any reputable manufacturer of goods amounting to a major purchase would want to have an enormous spares inventory, right ? - Wrong.

The company accountants hate spares stock, without being directly aware of it, the shareholders hate spares stock, and the bank don’t want to fund spares stock. It’s simply dead money. Money tied up for years and years as a speculative practice in anticipation that loyal customers just may one day agree to purchasing your stock parts at an unavoidably overinflated price. Another reason is the enormous depreciation of spares. Imagiine if you were a manufacturer holding a vast spares stock of mechanical, electrical and electronic components for obsolete (i.e. no longer in production) end products. Most of this stock purchased in good faith from premium manufacturers has no warranty, because the warranty that the parts were supplied with has expired whilst the parts were sitting on the shelf. However, when a customer buys one of these parts, you, as the supplier need to stand the warranty.

If we take as another example a simple machined part such as a bracket, handle or lever that that was a standard part on a 2012 end product that a consumer wishes to purchase as a replacement part in 2017. These would have been manufactured by a 3rd party supplier during volume production runs, resulting in a relatively low unit cost. If this part is no longer used on todays models, and as the manufacturer you don’t have any left (which you almost certainly won’t as you’re only too well aware of the pitfalls of holding obsolete stock), through your normal company procedures, the only way to supply one to your customer is to have the third party manufacturer, or an alternative supplier make you a “one off”. In this case, what was a £23 machined bracket which featured on every 2012 model can very easily result in a £350 retail asking price, not to mention the weeks or often months of lead time. The reason for this is that the 3rd party supplier is full to capacity with volume production runs (If they’re not, they’ll soon be in trouble too !), and are not going to stop everything at the drop of a hat to make a one off which involves setup time and associated cots, and sometimes dedicated tooling.

Just taking a few of these examples into consideration, it doesn’t take long to realiise how quickly the value of spares stock depreciates, and more importantly as an organisation that this is the last area of the business in which you want to invest and tie up your hard earned profits.

Most complaints and comments made in agreement regarding difficulties in obtaining spares often use phrases like “they should” or “as a loyal customer I would have expected” or more recently “When will they learn”.

From the perspective of a loyal customer, I agree that they should. However, any medium to large manufacturer of luxury products still in business today has indeed learned, and learned very well that even a moderate investment in spares stock for obsolete production models is a financial disaster.

Despite having read these points, I believe the view of the average consumer would still be that any reputable company would indeed still have a huge spares stock inventory as this is the primary aim of the business, to serve the customer, customer satisfaction, so that they remain loyal, right ? - Wrong. Any business has a single aim, and a single purpose, to make money. Unfortunately for the consumer, as long as failure rates are not significantly above the industry average, the future revenue lost because the most discruntled customers went elsewhere for their next purchase is many times less than the financial rewards associated with operating on todays choice of business model as a modern manufacturer, whose market demands the launch of a range of shiny new products every year, or even every few months.

As some members have correctly pointed out, there are obligations within many market sectors to supply spares parts for a number of years after production ceases. However, there are no specific obligations regarding the price or availability of same.

As previously mentioned, there are of course exceptions to the examples and points above, and even industries where the above does not apply, or applies to a much lesser extent, the automotive industry being one of them, due to sheer production volumes and other factors beyond the scope of this post.

Apologies for the lengthy post, the aim of which again is not to defend what ultimately amounts to poor customer service, but to hopefully offer a different perspective and insight into at least one of the reasons why trying to obtain spare parts can often be a difficult and frustrating experience.

I am as emmerson on battery drills (leg winders!) I have a cupboard full (literally) of perfectly serviceable drills, but unfortunately no batteries to power them. Each time a drill becomes unserviceable because of 'kaput' battery I have searched for a replacement battery., - always to find out that the replacement battery is more (or nearly as much) as a new drill. Is it a manufacturers conspiracy? So get a new drill. What a waste! But still reluctant to throw the drills away, I suppose waiting for a miracle and expecting the battery fairy to start supplying replacement batteries at a sensible price. (Pigs might just fly!)

THANK YOU for just giving me an idea. I have a collection of battery less drills too. When I read your post, it occurred to me to check if any of them ran on 12v dc. Bingo,one did.
I now have a 12S plug, a fuse, an old lawnmower lead and the drill all connected up and of course this drill will never need a battery again. As it was previously useless I can leave it in the caravan. Sorted!

Thank you Icarus

A very interesting post,

Another aspect that affects the need for spares is quality, which is a subject the caravan industry conveniently seem to brush under the carpet.

From my own research, and experience, poor quality control or quality assurance can become a very costly logistical nightmare.

In the 1980's we used a gas control control valve that was supplied by reputable company under a Quality Assurance scheme. It was a standard catalogue part and was used by at least three other major appliance manufacturers to the caravan industry.

I do not know exactly how it was allowed to happen, but the valve manufacturer changed the specification of one internal component. There was no outward visual change to the assembly, and initially it worked faultlessly, so it passed all standard production line testing.

Overtime, we, and other appliance manufacturers started to get calls about the flame failure system not shutting off gas flow when a flame had not been established. This was clearly a very worrying situation. We collected a number of the faulty valves and returned them to the manufacturer.

Ultimately this resulted in a recall. The valve manufacture had identified the batch date the change had been implemented and delivery dates to their customers, and fortunately because it is part of the approvals requirement we were working too we could identify the serial numbers of the products where the suspect batches would have been used, and we could identify which caravan manufacturers had received the appliances.

However the caravan manufacturers did not record the serial numbers of the appliances fitted to each caravan, and could not tell us specifically which caravans would be affected, or where the caravans had been shipped too.

In conjunction with the other affected appliance manufacturers we had to issue a nationwide newspaper recall notice, and set up a task force to receive customer calls and to coordinate the replacement of any potentially faulty valves, at customers homes, dealerships, and at manufacturers storage yards. The biggest challenge was trying to find those caravans that had been sold to end users, they were poorly recorded by some of the dealerships.

As a measure of success, we were able to find and arrange the replacement of about 95% of the potentially affected products.

To put this into perspective, the Valve manufacture's single component change may have saved them £0.02 per valve, or a total of about £200 but the cost of the logistical exercise -Phone calls, Research and testing, inter company coordination, wages/salaries, and additional cover, parts costs, transport, time and concern would have run up a bill per appliance in the region on average of about £80 per valve or a total somewhere in the region of £640K (1980's prices) or nearly £3M in todays money.

Not only was there a financial cost, but it stretched the elastic of goodwill a to almost breaking point with some customer and businesses.

It just goes to show that by doing it right first time, is a lot cheaper than allowing faults to get out of the factory gate.

This is a lesson the majority of caravan manufacturers simply do not seem to understand, you have to design quality in, you cant just apply it at the end of the production line, it has to be teh ethos at every stage, from the MD downwards through the whole organisation.

I agree with the Prof but unfortunately many accountants just see the upfront price and worry about the implications later. Every thing you see reviewed these days looks at what an item will do when purchased, but quality is very often missed in favour of up front price.

And that is another of the misconceptions that Quality costs! A properly designed product may cost a little more to design, but savings are made because it goes together correctly first time. reducing rework and scrap. It reduces any final delivery issues, and the customer goes away happy - win win.

I honestly believe that if caravan manufacturers were to try harder, yes it may cost a little more in production, but it will cost less in after sales rework, with a net increase in overall profit, but even if it were a break even situation, customers would be happier, and dealers could spend more time offering better customer experiences.
