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.
53
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 $53,207.25
per year. 10% increment every year.
PS: $15 dollar is the average salary in USA
54
ROI Analysis
Year 2016: 5,000
Growth Rate: 50%
Number of users = 5,000 * 1.5 ^ (Year - 2016)
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 2013.
4. The number of the black students graduate from
college every year, about 1.5million.
55
ROI Analysis
Benefit:
1. Advertisement
a.
b.
c.
$0.02 for each page view and $0.25 for per click on the
adv from AdSense
30% users will visit the website every day and view 4
different pages. 1% of them will click an adv every day.
Selling banner advertising $1 per 1,000 page view. There
is an increment 5% each year
AdSense: User * 0.3 * 4 page view * $0.02 + User * 0.3 * 0.01 * $0.25
Banner Advertisment: User * 0.3 * 4 page view / 1000 * $1 * 1.05^t

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.
58
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.
59
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.
60
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.
61
NDI/NCS Analysis
NDI/NCS Products
Purposes
