Purchasing Contracts Management System MSE Project Presentation II By: Arthi Subramanian

Basic functionality addressed in Phase I Search Functionality: Search across fields such as: Contract Number Contract Title Procurement Officer Vendor Keywords - Further search all the above fields  Retrieve all the contract details.

Additional Functionalities – Phase 2 Add contracts: Login required. Include new contracts to the system. Administrator functionality – Procurement officer (Purchasing Department, Kansas State University). Basic Details. Department Details. Associated File. Comments (Eg: Replaces 14223).

Formal Requirement Specification Classes: User, KSUDepartments, Administrator, Department, Vendor, SessionManager, Contract, SearchFacade, File, Keywords Operations: addContracts(ContractID:Integer,ContractNumber:Integer,ContractTitle:String, ProcurementOfficer:String,Vendor:String,Start:String,End:String,DepartmentName:String, ApprovalDepartment:String):Boolean pre contractpre1: Contract.allInstances.ContractID -> excludes(ContractID) pre contractpre2: Contract.allInstances.ContractNumber -> excludes(ContractNumber) post contractpost1: Contract.allInstances.ContractID ->includes(ContractID) post contractpost2: Contract.allInstances.ContractNumber ->includes(ContractNumber)

Additional Functionalities – Phase 2 Search Functionality improvements : Search by keyword includes searching across: Contract Number Title Vendor Procurement Officer Department Master file keywords (defined prior to upload) Comments Tool-Tips indicating which departments pre-approval is required. Link to master contract file.

Formal Requirement Specification class SearchFacade operations getallContractsinDepartment(d:Department):Set(Contract) = Contract.allInstances ->select(c:Contract | c.belongstodept = d) getbyVendor(v:Vendor):Set(Contract) = Contract.allInstances ->select(c:Contract | c.belongsto = v) getbyContractNumber(ContractNumber:Integer):Set(Contract) = Contract.allInstances ->select(c:Contract | c.ContractNumber = ContractNumber) getbyProcurementOfficer(ProcurementOfficer:String):Set(Contract) = Contract.allInstances ->select(c:Contract | c.ProcurementOfficer = ProcurementOfficer) getbyKeyword(Keys:String):Set(Contract) = Contract.allInstances ->select(c:Contract | c.ContractTitle = Keys or c.ProcurementOfficer = Keys or c.ContractNumber = Keys or c.associatedwith.contains.Keywords->includes(Keys))

Additional Functionalities – Phase 2 Update functionality: Login required. Includes search functionality (search and edit). Contracts already existing in the system. Ability to display and edit multiple contracts on single search. GUI – Ease of performing updates. New master file upload.

Test Plan Ensure the system meets all the requirements stated in the software requirement specification document (SRS). Test plan includes – features to be tested, approach for testing etc Sample Test Case: Purpose: Test that administrators are able to search details of an already existing contract. Actual Input Enter a search text, set the search filter to keywords and click on search Pass criteria The text must be searched across the contract number, contract title, vendor name, procurement officer name, comments and the keywords of the uploaded file. The contract details corresponding to a successful match must be retrieved with a link to the master contract file. Expected Input Enter a search text, set the search filter with respect to the type to search to be performed. Pass criteria The contract details are retrieved from the database and populated in the grid. Steps 1.Visit Contracts.aspx Web page 2.Enter a contract number in the search textbox and set the search by filter to ‘Keywords’. 3.Contracts that match the search criteria must be populated in the grid.

Performance Testing Tool : Jmeter The following components are analyzed for performance. Searching for contracts Updating: Searching for contracts, selecting a contract and further updating it. To Measure: Response time for each component Throughput Identify the acceptable criteria, the key scenarios, design tests, run tests, analyze results.
