The Classic version of Salesforce.com followed a more “Amazon” style of presenting various objects (Leads, Accounts, Contacts, etc.) in a tabbed format, and then had organized each in vertically ordered sections which required scrolling to see different sections.
The Salesforce.com Lightning version streamlines the workflow especially for Sales by using more modern layout design principles and capabilities. It enables administrators to compose the desired layouts by arranging various components (activities, accounts, contacts, custom objects, etc.) as desired in a dashboard or console way so as to minimize scrolling and bringing the most important information a particular role needs at the top.
SOMAmetrics assists clients in the migration of their current classic version of Salesforce.com to Lightning and provide users ongoing support and training to develop proficiency using this new user interface within days.
