Topics can be described as more narrow perspectives within an area.
Here's an example: If you create an area called "Relationship" you need to narrow it down at the topic-level. You can divide the relationship area into four topics such as:
- Our relationship with internal and external influencers
- Our relationship within the user community
- Our relationship with decision makers
- Our relationship with approver/signing authority
As a result, you narrow an area down with topics until it becomes action-oriented and practical by adding questions.
Best practice is to have as few topics as possible in order to keep the total amount of questions to a reasonable amount. However, it's still important that all aspects are identified and covered. In the image below you see the Relationship area with four topics.
