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.
A good template will provided a step_by_step approach with explanations as to why each step is proposed. The strength of the marketing plan derives from the integration of each step. So if you leave out a step, you may undermine your own plan.
