Looking ahead at the specific industry of which your service business or professional practice is a part is also important. To determine which trends are significant to you, explore the marketing elements of your industry. These include the following: general changes in your industry, changes in services in your field, pricing changes, changes in the way your service is distributed or delivered to your clients, possible changes in promotion, changes in the clients themselves.
