Sheepdog, you're right - the content has to be provided, and someone has to check that is HAS been provided. There's both a content management issue and a business process one.
A good content management system (an expensive software facility) will publish content according to instructions...IF the content is there. For example, every time an item is published to the live 'in stock' site, the programmed rule should demand a photograph of the item before publishing, and refuse to do so if the photograph is missing (publishing means uploading the content to a server so that punters like you and me can see it). Where an item's photograph cannot be obtained (eg, Ralph has not yet brought the Honora items across the Atlantic), the item should be flagged as Pending, not made available, and should trigger a review at regular intervals. At the very least, it should be possible for The Management to obtain a report about all items that are missing important details. Clearly, this is not possible, or is not bothered about. They either have poor software, or poor business processes.
I get the strong impression, as you suggest, that much of the content management is outsourced to an unskilled team, and that pretty much NO quality control is present. Errors on the site are rarely (I'd say never, but perhaps I've just not seen the exceptions) picked up and corrected, which suggests that no-one is tasked with QC, and that there's little budget expended on doing so.
Amazon, who offer thousands of times the number of items that QVC do, with a lot more complexity in terms of vendor type, manage a much higher level of consistency. Loads of other online vendors offer a more satisfying and reliable user experience. QVC no longer has many unique offerings (eBay has ended much of QVC's exclusivity). They are really going to have to think hard about how they present themselves and retain market share in a cold economy.
The pensioners buying Nina Leonard over the phone and calling in for a chat with Julia seem to me to represent a static/dwindling market...unless of course, QVC have spent some cash on analysis of the market and can prove me wrong.
