- We first identify the primary and secondary actors in the case study
- Then we identify the actions performed by each actor to draw use-cases
- We identify the relationships between the use-cases
- Then we identify the relationships between the actors
- We then identify the secondary actor involved with the use-cases

first we try to under stand the complete scenario of case study in and out and later we have to identify the primary and secondary actor then we have draw the system boundary in that system boundary we have to create a essential use cases and and identify the connection and draw the relations between the use cases and actors and we have to mention complete sequence an use cases briefly.

The steps involved in drawing a use case diagram from a case study are:
1. Analyze the different actions to be performed as per the case study.
2. Put all the actions in a sequential order.
3. Analyze the actor who is performing the actions in case study.
4. Figure out essential use case and supporting use case.
5. Identify some modules with respect to functionality or usage.
6. Formulate the relationship between Actors and Usecases.
7.Information which we do NOT model in Use Case diagrams are
➢ Names of the systems (laptops, Desktops, Workstations),
➢ Architectures (2 Tier, 3 Tier, n Tier, Client Server),
➢ Databases Names (DB2, SQL Server, My SQL)
➢ Networks (LAN, WAN, Internet),
➢ Brand Names (HP, Lenova, Wipro, Sony),
➢ Technology Names ( Java, .Net, Mainframes)
