In every industry and business, there are specific vocabulary terms that are included in the daily tasks and operations. Every employee should be familiar with these terms and an understanding of what they mean. Also, they should understand how they are implemented in the industry. Sometimes, certain words can have different meanings, but they mean something specific in a certain industry.
Likewise, the employees should feel free to ask questions about the business vocabulary. However, it would be better if the business leaders would create a concept model of the business terms so that the employees as well as any others associated with this business understands and is trained on these terms. All of the business terms should be used consistently in the rules and procedures.
