6. Project Modules Admin Module Definition: Administrator : Procurement Officer Interacts with the system through a webpage. Roles: Logs in to the system. Inserts contract details. Searches for contracts before performing edit. Edits existing contract details.

7. Project Modules End-user Module Definition: Users :  University officials and employees who purchase services, supplies or equipment.  Facilities, human resources, telecom department officials. Interacts with the system through a webpage Roles: UserRole University officials, employees Search for the contract details. Facilities, human resources, telecom department Search for contracts that requires the respective departments approval.

11. Application Requirements AR1 : User Interactive graphical user interface AR2 : Authenticate valid procurement officer AR3 : Search based on – Contract number, contract title, vendor, Procurement officer, keyword AR4 : Search by keyword must search across contract number, contract title, vendor, procurement officer, comments AR5 : Results must include details such as departments whose pre-approval is required. AR6 : Contract files (master contract document) must be made accessible through Kansas department of administration. AR7 : All contracts must be displayed when requested to do so. AR8 : For any unmatched search fields, a message with possible suggestions must be displayed. AR9 : If a contract with expiration date lesser than or equal to start date is entered by the procurement officer, a message must be displayed and further data entry must not be allowed until corrected. AR10 : Search results can be sorted in ascending/descending order.

13. Project Schedule

14. Cost Estimation COCOMO II is used to estimate the duration and cost involved in development of a system. Considers factors such as reliability, software development complexity, memory Usage etc. 2.45 * EAF * (KSLOC) ^1.09 Time = 2.5 * (Effort) ^ 0.38 Effort = Number of person months (PM) Time = Duration time in months for project KSLOC = Estimated number of source lines of code for the project (in thousands) EAF = Effort Adjustment Factor Effort = 2.45*0.523*(1.8)^1.09 = 2.43 man-months Time = 2.5 * (2.43) ^ 0.38 = 3.5 months
