Sustainability is the goal in all this, really. Making sure that you can deliver in ALL aspects of business with or without a team - for a prolonged period of time without the disruption of your life.
Now, to do that, you need to be moving in alignment with your business. Identify the gaps. Identify the needs. Seek the tools.
But the only way to get that eagle-type view of your business is through the establishment of your systems.
Your systems end up being the blueprint of your business. To show you the weak spots, entrances, exits, etc, at a glance.
Give yourself the chance to get that deeper view of your business.
