I usually do not answer questions that look like a homework, but I'm going to assume that this is not.
The stakeholders in your project are the following:
- The school director
- The finance department of your school
- The users of the computer based system
The objectives are:
- Facilitating library work
- Facilitating reporting (checking which books are overdue, etc...)
The success of the project can be measured based on the reduction of the amount of labor to process library work when the project is done. If the amount of labor remains the same or increases, then the project has effectively failed.
