You need to explain about the below things in detail.
- Domain of the dashboard (finance/Sales/Supply chain etc)
- Target users (sales executives, Managers, customers, CEO etc)
- Data sources used
- Connectivity used
- explanation about fact and dimension tables
- Data model creation and its challenges
- reload time, frequency and type of reload (Incremental load if any)
- List of KPIs used
- List of Charts for each KPIs
- How the KPIs benefited the end users (eg: My receivable amount overdue dashboard helps the client to collect 2M USD extra each week etc)
- Security applied in the dashboard
- Number of users
It's better to explain the things based on the role you played on the project .
