Hi Praveen
Number of dashboards depends on a lot of factors.
Mainly the complexity of the dashboards and the knowledge/experience of the developer.
I have had a dashboard that has taken 3 or 4 months to get to a stage of release and still required further iterative development. In contrast recently i have built and deployed 6 dashboards in last 2 months
As for a project lifecycle in general it would be something like the following:
- Scoping
- Gathering Requirements
- Planning,
- Executing (Develop/Test/Change/Verify)
- Deploying
- Training and support
Hope this helps.
Dan
