This article will give you the six parts of a basic marketing plan template that will work for any business. Those parts, or sections of the template, are: Situation Analysis, Target Audience, Goals, Strategies, Tactics, and Budget.
However, if you do not want to spend money or you cannot find one that would suit your training ideas, then try the integrated approach. You can look up other companies' templates online and then make a few revisions to make it fit your own approach. If you are lucky, you might even stumble upon a training plan template from a company that is within the industry your business belongs to.
