Even inside LCC one of the 'Nick Assef Principles' is to review the cost base on a quarterly basis, challenge all service provider agreements and any other expenditure. And this is not necessarily to just save money.
Our challenge as a Firm has been to get the best possible tools and staff. Every time we save some money we can afford to upgrade our resources. So it is well worth doing.
I recommend you take a couple of hours to really study the cost basis of your operations every few months. It is a simple but effective exercise.
