As you well know, data analysis is crucial to your business. It's especially relevant to construction, remodeling, interior design, and Real Estate businesses that have been hard hit by this economy. It may be time to pause and take a hard look at what you are doing right and wrong. The key here is your business data, from accounting numbers to sales modeling. This will help you make business decisions to promote growth and to avoid areas or markets/clients that sap your strength and don't add anything to the bottom line.
