Stick to what you do best. Don t diversify too far beyond that yet. Sticking to what you do best also applies to you personally. So in other words, if your strength is in bringing in deals, delegate to someone else internal operations so you can spend most of your time bringing in sales. Or, vice versa, if you re good at operations, handle the operations and bring on good sales people.
Delegation is the point here.
Delegate to others so you can be more effective. As you grow, you will need to develop some type of structured system for your organization. Systems, or the lack thereof, that work well in start-ups may not work all that well for growing businesses. As your company grows, the system will continually have to change and adapt along with that growth. Consequently, you will need to adopt a system that is flexible.
