Vision

A Vacation Tracking System (VTS) will provide individual employees with the capability to manage their own vacation time, sick leave, and personal time off, without having to be an expert in company policy or the local facility’s leave policies.

Functional Requirements

Implements a flexible rules-based system for validating and verifying leave time requests
Enables manager approval (optional)
Provides access to requests for the previous calendar year, and allows requests to be made up to a year and a half in the future
Uses e-mail notification to request manager approval and notify employees of request status changes
Uses existing hardware and middleware
Is implemented as an extension to the existing intranet portal system, and uses the portal’s single-sign-on mechanisms for all authentication
Keeps activity logs for all transactions
Enables the HR and system administration personnel to override all actions restricted by rules, with logging of those overrides
Allows managers to directly award personal leave time (with system-set limits)
Provides a Web service interface for other internal systems to query any given employee’s vacation request summary
Integrate with the HR department legacy systems to retrieve required employee information and changes

Non-Functional Requirements

The system must be easy to use(reusable)
Save time and money mostly in the HR department
Improve the internal business processes of this organization, at least with respect to the time it takes to manage vacation time requests

Constraints

Integration: Integrate with HR department legacy systems to retrieve employee information and changes
Single-Sign-On (SSO): The VTS must use the Central Authentication Service (CAS) for user identification, as it is an extension of the existing company intranet portal
Hardware: Uses existing hardware
Integration as an Intranet Extension : The VTS is explicitly defined as an extension of the existing company intranet portal . By building it as a Web-centric application integrated into the current infrastructure, the system provides a natural entry point for users who are already familiar with the company's internal tools
