Final answer:
The most effective mission statement is 'Our soap works for you so you don't have to work' as it clearly communicates the product's purpose and benefit, which is a good match with the chapter's objectives on the cleansing action of soap and its benefits.
Step-by-step explanation:
When evaluating the effectiveness of mission statements, it is essential to consider how well they articulate the purpose, values, and direction of an organization. Among the given options, the most effective mission statement is the third one, 'Our soap works for you so you don't have to work'. This statement provides a clear and specific purpose of the product, which is to make cleaning easier and save time for the customer. It implies the benefit of using the soap effectively, which aligns with the cleansing action that is a learning objective in the chapter on cleaning with soap. A good mission statement also illustrates the unique value proposition of the product or service.
Option three is effective because it not only states the function of the soap but also encapsulates a significant advantage over other products—that it works effectively so customers don't have to exert effort in cleaning. This easily relates to the benefits of using soap, which includes its ability to clean surfaces by emulsifying oils and holding dirt in suspension, making it easy to rinse away. While option three doesn’t explicitly present any problems associated with the use of soap, its strengths lie in its focus and customer value proposition.
