Question

You are given the following information:

Business Requirement: Web application must detect and prevent ghost employees in an organization using a biometric time and attendance and access control device

Your task is to come up with functional and non-functional requirements for such a web application, using the following sub-headings:

1.Cut off all employee salary payments from pay roll

2.Configure Systems process of payroll payments upon biometric verification

3.Take a photograph and copy/scan of ID

4.Take fingerprint/s

5.Run the record through a deduplication system (biometric fingerprint system)

Answer 1

Functional requirements

• hardware resources - computer system , 1GB hard disk space , A scanner to scan images
• Software needs
• The software should be very freindly and should provide accurate results
• The selected image should be saved to system memory and keep save the original file till the result is displayed.
• Matching two similar fingerprint images and two different images.
• The user when compare two images, if both are similar it should display a message both images are matched otherwise display both images are not matched.
• The software should have exit button to stop the process.
• It describes what the software/ website should do (functions)
• Because the functions are established before the development
• functional requirements should be written in future tense
• All the data of employees should be verifies and updated
• All the input and output by the employee
• The image of the employee in the data is essential for verification
• Unique fingerprint for different emplyee will varry accordingly

Non functional requirements :

• usabililty

     The image comparison software should be user friendly and easy to understand. Interface should be comfortable so that it will be easy for the user to operate. The tool must be intuitive or easily understood after the tutorials and user guide. Display should be presentable.

• Changeability

     The software should be designed in such a way that any future modifications or improvisation can be done with much more functionality.

• Efficiency:

     The project must be efficient such that it can select image and display in scaled manner within the GUI. Software should provide reliable result.

• Portability:

     The system should be able to run on any platform. This project runs on windows 98/2000/ XP/vista operating system. It should have java virtual machine (JVM) in the operating system and Xinox Software Jcreator LE.

• Understandability:

     The fingerprint matching software should enable user to understand whether the software are suitable. The software should be understandable and easy for user to know more about fingerprint matching and make further development in future

• Is the person authorised to enter this facility
• Is this individual entitled to access the privileged information?
• Is this given service being adminstered exclusively to the enrolled user?
• is the fingerprint valid or not?
• is the image valid or not?
