E- PROCUREMENT WEB PORTAL

5. OVERVIEW

The conclusion part summarizes the project according to the objectives outlined at the beginning of the project, as well stating its advantages and the recommendation part explains on how to enhancethe system in terms of securityand confidentiality.

5.1 Conclusion

As a conclusion, this project is to handle procurement activities in an electronic environment where it enables better management of the information and knowledge exchanged with suppliers and customers. A prototype for an e-procurement system has successfully been developed to handle procurement activities in electronic environment. An e-catalogue with listings of equipments has been designed and integrated with the system. Those who make the switch to e-procurement often find that they smooth out relationship glitches with preferred suppliers, often establishing a relationship which is a better long-term pricing.

In the objective and scope, it has been stated that this project prototype consists of graph representation. But due to some programming error and lack oftime, the graph

could not be produced.

5.2 Recommendation

Anonymity is the most prominent feature of electronic tenders. Conventionally, vendors had to obtain tender documents inperson, which may result inbid collusion.

Alternately, via the electronic process, vendors can execute all required processes through the Internet. Anonymity is secured and hence reduces the possibility ofbid collusion, which is notably theprimary purpose of this system.

However, due to the openness of the internet, documents transferred on this system

can be retrieved by hackers. So it is recommended that in future this system will be

upgraded where the documents transferred are coded. Additionally, as electronic

signatures aid in source verification and determine document reliability, each tender

document must bear the private key of the managing organization,
