The first step to creating a sales training plan and budget is to assess your sales training needs. This means identifying the gaps and opportunities in your sales team's competencies, behaviors, and results. You can use various methods to assess your sales training needs, such as surveys, interviews, observations, tests, or performance reviews. You should also consider the feedback and expectations of your customers, prospects, and stakeholders. The goal of this step is to prioritize the most critical and urgent sales training needs that will have the most impact on your sales performance.
