Michael is a manager of a landscaping business. during a particularly dry season, he realized that he had the opportunity to increase his sales if he could find a way to ensure that his plants would stay in bloom despite the dry conditions. he brainstormed with his employees and the best two ideas they had were to develop an innovative irrigation system to water the plants from underground and to focus on selling dry-weather plants. he determined that the underground irrigation system would be too expensive for his customers, so he decided to focus on selling dry-weather plants. he found a new supplier of dry-weather plants and had his employees focus on selling them to existing and new customers. what must michael do to determine if his decision accomplished the desired result?
