Developing a Social Media System

California State University, Los Angeles

December 12, 2016

Implementation

The social media system will allow people to network with other people by sharing media, posts,

create groups, events, and sell products. We create an account and a user must register through the app

or website as an initial step for using the system.

The user will have to enter some personal information and create a password and a user ID.

From there, the user will automatically have a profile which the user can add to or modify, and the user

can update their profile picture and cover photo. He/she can search for other users by typing their

username in the search engine. The user can also share posts by uploading media such as videos and

pictures or can use the textbook to type text which automatically includes a timestamp and location

when posted.

We will create and design the mobile app first because mobile devices have the most

limitations, such as screen size and bandwidth, thus content will be prioritize when designing and

creating the app first. To create our app, we will create an account and use BuildFire.

After development of the app, we will test the security of the app. We will have trained

developers design the app to cover all security patches and vulnerabilities issues. Additionally, we will

train our developers how to implement, code, and design the app to be secure to prevent the app from

crashing. Lastly, there will be maintenance and updates. This development process with the app will

take about 6 months.

After the process of developing and performing the vulnerability testing for the app, we will

start developing the website. We will be developing our website by buying a domain name and a hosting

account or a hosting provider that gives us a lot of storage and bandwidth. Similarly, we will have to

perform vulnerability testing on our website too through the free open-source software, Wapiti that I

found on sourceforge.net. This will take about 3 months.

After the development of our website and app, we will establish guidelines and polices on how

to use it and all users and developers must comply with it.

In order to manage our social media pages, we will have to appoint a Director of Public Relations

(PR) and hire a marketing team. These people should be professional, have interpersonal and listening

skills, be professional, respond timely, and are knowledgeable in their professions. Plus, we have a

Webmaster to create, design, update, and perform frequent maintenance on our website. To fund our

site, we will seek venture capital and crowdfunding, and we will promote our site through other social

media platforms such as Facebook, Snapchat, Instagram, Pinterest, and Tumblr and streaming sites like

YouTube.

There will be weekly meetings with the PR Director, the Webmaster, and the App Developers to

discuss about the overall progress of the project and to brainstorm ideas for the short-term and long-

term objectives through virtual conferencing and general meetings. Furthermore, the key points of

these meetings will be written down and recorded by the secretary to keep records stored in a

database. The secretary should be efficient, reliable, communicate effectively, and maintain high

confidentiality.

Scope

We expect to expand to about 100,000 users and have some profit from advertisements.

Nonetheless, the purpose of the social media site is help users network among other users, to help

businesses market their service or products through word-of-mouth, and to let users build a social

media presence. So, we will think of new ways on how to improve on the system.

Due to the popularity of social media sites, there are many examples of it. There are many

prominent social media sites such as Facebook, Snapchat, Instagram, Pinterest, StudyRoom, and Tumblr.

The first step is to fund the project through networking with investors, seek venture capital, and

other types of funding. This will have a duration of a month.

Next is to develop the app. We will create and design the mobile app with BuildFire. This will

take 4 months.

After development of the app, we will test the security of the app. We will have trained

developers design the app to cover all security patches and vulnerabilities issues. Additionally, we will

train our developers how to implement, code, and design the app to be secure to prevent the app from

crashing. This will take 3 weeks.

There will also be maintenance and updates. This development process with the app will take 27

days.

After the process of developing and performing the vulnerability testing for the app, we will

start developing the website. We will be developing our website by buying a domain name and have a

hosting provider that gives us a lot of storage and bandwidth host it for us. This task can be completed

within a day.

We will design, code, and implement components to our site. This will take about a month.

Similarly, we will have to perform vulnerability testing on our website too through the free

open-source software, Wapiti that I found on sourceforge.net. This will take about 2 months.

After the development of our website and app, we will establish guidelines and polices on how

to use it and all users and developers must comply with it. To establish guidelines and polices, we will

produce documentations of it. This will have duration of 1 week.

Lastly, we will invest in promotions by advertising on social media sites, streaming sites, blogs,

investing in SEO tools, and optimizing in search engines and business directories. This will be

accomplished in a week.
