It's hard to do because it's hard to measure. Organizations mainly do what the people up top want done. And in a large, top heavy organization, the people at the top mainly manage by spreadsheet, that is, judging a business unit's relative effectiveness and worth by metrics and key performance indicators. Since it's hard to quantify customer satisfaction on a spreadsheet, but easy to quantify (and thus reward) profitability on a spreadsheet, then profitability is what middle management is going to pursue.
You can't just wave your hand and say "this year we are going to focus on the customer" and expect it to happen. You can't even put money towards customer appreciation initiatives, although of course that helps, because everybody knows what the higher ups really care about.
If you really want to focus on the customer, you need to find, recognize, and promote people who actually do that. You need to create programs that support the customer and then actually nourish those programs. And you need to invest in areas that don't directly lead to short term profitability, like tech support and customer service.
The old Pelco, for example, knew how to focus on the customer, and they were rewarded by intense customer loyalty, long after there was any reason to remain loyal. Hikvision, for all its faults, knows how to focus on the customer; they have enough foot soldiers on the ground that individual reps can lavish attention on the sort of little dealer who the bigger manufacturers ignore, their constant product updates means that they always have awesome new features, the product is cheap enough that returns are never a problem, and their QC isn't half bad. In return, their customers reward them with the sort of fanatical loyalty we see on this very forum.
But a company that doesn't already focus on the customer will have a very hard time changing that. It takes years, and a fundamental restructuring of exactly what it is the company actually does.
It's not a matter of cash. It's not a matter of will. It's a matter of inertia. And the bigger the organization, the harder it is to redirect it.
