Why to make a business change: Not because vendors are begging you to. Instead, focus on what customers are demanding, and also track your margins to see if your current model is losing momentum or in need of fine-tuning.

When to make the change: Make sure you have the money to make the change. Also, make the change before your business dashboard — signaling profits, revenues, etc. — begins to go south.

How to make the change: Build a go-to-market plan that's KPI (key performance indicator) based. Know your lead indicators to help track if the strategy is working before clear outcomes are know.
