You can argue about it. But your customers are looking for solutions right away. Overnight is too slow. The Internet provides the ability to respond immediately. Your company's marketing plan, coupled with the speed of the Internet, provides you with a sales tool like no other.
Speed is one of the key elements necessary to make it in today's hotly competitive world.
Of course, speed alone isn't the solution. Being there first with the wrong stuff or not enough of the right stuff makes you look like Willie Coyote about to get slammed with another anvil. Be the first to provide what your customers want and the most of what they want. Find ways to serve your customers and prospective customers faster. Use the Internet.
