The sales (or marketing) plan is a list of targets to achieve. These targets can be sales dollars, unit volumes, growth levels, new markets to enter, or market share. Sub-lists can be developed to address products, territories, major customers, advertising, and even individual salespersons.
A checklist is a list of items or tasks that you "check off" as you complete each item/task on the list. Checklists are everywhere and are an integral part of most activities - both personal and business. In our own daily lives, we make checklists for organizing, planning (birthday party), prioritizing (bills to pay), shopping (grocery list), and so forth. Business is no different; checklists are essential to an effective, efficient, and profitable operation.
