Final answer:
The property that segments ideally should NOT possess is defensible.
Step-by-step explanation:
To answer the question, we need to understand the properties that segments ideally should possess. The four properties that segments ideally should possess are:
1. Identifiable - Segments should be identifiable and distinct from one another, allowing for targeted marketing efforts.
2. Sizable - Segments should be large enough to warrant marketing efforts and generate sufficient revenue.
3. Defensible - This is the property that is NOT a property that segments ideally should possess. Defensible segments cannot be easily replicated or attracted by competitors, providing a competitive advantage to the company.
4. Accessible - Segments should be reachable and accessible through marketing channels.
5. Actionable - Segments should be actionable, meaning the company can effectively target them with marketing messages and campaigns.
In summary, the property that segments ideally should NOT possess is defensible.
