53 ROI Analysis Cost: 1.The effort paid by the client during the development period and the effort during the maintenance period. 2.The cost for deploying the system. 3.The cost for upgrading the system. Benefit: 1.Income from advertisement.

54 ROI Analysis Cost: 1.42 hours for development period * $15/hour 2.52 hours for maintenance period per year * $15/hour 3.Amazon Web Service (m1.medium) $134 per year in LA 4.A ruby programmer' salary is $70,943 per year, and we assume that we hire 3 ruby programmers to update the system in 3 months per year. That is about $53, per year. 10% increment every year. PS: $15 dollar is the average salary in USA

55 ROI Analysis Consideration on the number of users 1.Marketing. 2.Competition from other similar website. 3.Growth rate the number of users. a. Number of users in Linkedin doubled every year from 2009 to 2011, and increased by 50% from 2011 to The number of the black students graduate from college every year, about 1.5million. Year 2016: 5,000 Growth Rate: 50% Number of users = 5,000 * 1.5 ^ (Year )

56 ROI Analysis Benefit: 1.Advertisement a. $0.02 for each page view and $0.25 for per click on the adv from AdSense b. 30% users will visit the website every day and view 4 different pages. 1% of them will click an adv every day. c. Selling banner advertising $1 per 1,000 page view. There is an increment 5% each year AdSense: User * 0.3 * 4 page view * $ User * 0.3 * 0.01 * $0.25 Banner Advertisment: User * 0.3 * 4 page view / 1000 * $1 * 1.05^t

58 Major Risk Similar Products in the market. Products such as Black Career Network provide features that are similar to our websites. The competition is inevitable. Mitigation Plan: Upgrade the system frequently after deploying based on the feedback of the users.

59 Major Risk System Maintenance and Upgrade: the maintainer for the website has not been decided. It is hard for client to maintain the website only by himself. Mitigation Plan: The client need to spend time in learning the web technology to maintain and upgrade the system by himself. Hire someone else to maintain and upgrade the system.

60 Major Risk Budget: Since the system we will deliver next semester has only simple features, the client may not be able to spend enough money on it (about several ten thousand dollars each year according to the ROI analysis) to make the website more engaging and provide a better user experience for users. Mitigation Plan: Find some investors who are interested in the project and ask them to fund the project.

61 Architecture Feasibility CR-8 Group Formation: The system is capable of allowing users to create groups; group creator serves as the manager, who can accept joining request. CR-9 Recommendation Letter: The system is capable of allowing users to write, to review, to accept and to reject recommendation letters.

62 NDI/NCS Analysis NDI/NCS ProductsPurposes RailsThe framework of back-end of the website. PostgreSQLThe DBMS for the website. Phusion Passenger Serves as a bridge between rails application and Apache web server for the project. ApacheThe http server for the project.
