This isn't a dig at you but, this is an example of what I meant a couple of days ago when I mentioned people taking incredibly complex situations and suggesting a really simple solution. I've specifically taken the "Chinese" part out of this post because there's absolutely no reason to distinguish between nationalities in this. Being at max capacity is both a blessing and a curse. You can't just invest in new facilities if you can't be sure that the demand will remain long term, this is how companies go boom and bust. Even if you can find a location you've got to be able to find the machinery that you need, and the staff to operate it...and then who trains these staff members when everybody you have on staff is already pushed to their limit? do you sacrifice productivity for a month or two?
So, great, you've made a massive upfront investment, found or built another building, populated it with machines, tools & a much larger work force, but can you source all of the parts that you need to double production? & what happens when your production capacity exceeds demand? you've now got double the costs without double the ongoing revenue. Can you survive in that situation?
it's a similar situation for us at the moment...phone lines jammed - "hire more staff" - but what about training? network capacity? phones? ongoing staffing costs once demand returns to normal?
Warehouse swamped - "hire more staff" - but what about training? Covid protocols? we've already got as many people as we can safely fit in our warehouse space..."get a bigger warehouse" - but what about our lease? what if we can't find a suitable location? "build one" - finding a site, planning permission, build, integrate network, move - that's a two year job at best.
"I'm fed up of waiting why don't you offer us an alternative card?" - see above, phone lines are jammed, we don't have the man power to contact hundreds of customers to have that conversation - "so hire more staff" - rinse & repeat - "allow us to do it online" - How? our website can't manage that - "get a new website" - We are! we've been working on it for two years already, off the shelf solutions don't exist for a company like us who require complex features such as those which you are asking for.
You see what I mean?
There are always complexities, blockers and long term considerations for ever apparently simple problem. People get angry because they believe that the solution to their problem is simple and think that companies are lazy or negligent for not carrying out said simple solution, but very few people truly grasp the actual magnitude of even the 'smallest' changes, and the bigger the company the harder it is to make such changes.
