Lovely Professional University
Introduction:LinkedIn is the world's largest professional network with hundreds of millions of
members, and growing rapidly. Their mission is to connect the world's professionals
to make them more productive and successful. It can help you:
1. Establish your professional profile and control one of the top search results for
your name.
2. Build and maintain your professional network .
3. Find and reconnect with colleagues and classmates.
4. Learn about other companies, and get industry insights.
5. Find other professionals in the same industry using groups.
6. Share your thoughts and insights through LinkedIn's long-form publishing
platform.
7. Tap into the knowledge of your network.
8. Discover new career opportunities by searching for jobs.
Purpose
LinkedIn is a business-focused social networking site that launched in 2003. Its main
purpose is to help people network professionally. The basic service is free.
The site lets you find other business associates, clients, and colleagues whom you
already know. You "connect" with them through the site, and they then become part
of your network.
Once you've connected with a person, you will then have access to their list of
connections – this is called your "extended network." You can request an introduction
to people in your extended network through your mutual contact.
LinkedIn also provides other features including the ability to set up and join groups,
and a jobs section where members can advertise open positions or apply for jobs.
Definitions, acronyms, abbreviations
Here are a few useful terms you should know when using LinkedIn:
 Connections – Connections are other registered users who you know personally
on LinkedIn. Although you can invite anyone to be a connection, they will need to set
up an account to use the site.
 Second-degree connections – These are the connections that your connections
have. For example, you're friends with Bill, who is directly connected with his boss.
Bill's boss is a second-degree connection for you.
 Third-degree connection – Any connections from your second-degree connects
are third-degree connections. So, Bill's boss's connections would be your third-degree
connections.
 Profile page – This is your personal page on LinkedIn. All registered users with
LinkedIn can view it (unless you set it to be a private page). Your profile page can list
your education, past work history, current and past projects, groups and associations,
and more. Users can also forward your profile page to contacts on their lists. You can
also make your profile page "public" so that anyone (even people not on LinkedIn)
can view it.
 Recommendations – Your connections can write recommendations, or
testimonials, for your profile. These can be a powerful testament to your business and
professional skills.
 Introductions – Introductions are when a third party introduces two people who
weren't currently connected. For instance, your colleague Sue and your client Dan
don't know each other. You think Sue could help solve a problem that Dan is having
with one of his projects, so you introduce Sue and Dan through LinkedIn.
Introductions are simply a way to bring people together on the site.
Scope
Eight years after its launch and a few short months after its $4.3 billion IPO
valuation, LinkedIn has quickly become the de facto tool for passive job searches,
living just on the fringe of the pure play job sites like The Ladders, Monster, and
CareerBuilder. In its blander sense, LinkedIn operates as a means for collecting
contacts and staying abreast of who is now working where. As for everyday business,
it has not woven itself into the social fabric in the same way as Facebook or even
Twitter. And whereas Facebook has managed to straddle the line between
desktop and mobile, LinkedIn has struggled.
Overall Description
Product Perspective
ALPHA Release - A Work in Progress (WIP) /unstable software release of a
product is characterized as an ALPHA. This product is expected to have basic issues,
bugs, even unforeseen crashes and is under active development by the R&D
teams.This ensures that a usable version of a product goes to the BETA stage with a
known list of punch points – which need to be resolved at the BETA stage.
BETA Release - A software release reaches the BETA stage once it has attained
stability in terms of critical punch points being resolved as per the test reports and
regression cycles. A BETA software release aims to fix the other major issues and
known bugs as part of frequent software release drops. At this stage, any feature gaps
with respect to the standards should also be addressed.
CANDIDATE Release - A software release reaches the maturity to be a
production CANDIDATE once all its known issues, and fixes reported by the quality
assurance team have been resolved. In order to evolve from this stage to become a
GA release, the software should address critical features such as high availability,
fault tolerance & load balancing. Once these criterion are met, the software evolves to
GA maturity.
GA (GENERAL AVAILABILITY) Release - A software release which has
attained GA maturity is fit for production quality after all the necessary
commercialization activities have been completed and a software product is available
for purchase in the market.
Product Features
Listed below are my Top 5 features of Linkedin
Posting Updates
This feature allows you to broadcast your interests and point of view. your contacts
would appreciate seeing the content and you will be providing a point of view based
on your unique set of experiences and expertise.
2) News "Signals"
Signals are a quick way to learn how many of your contacts are currently active on
LinkedIn, which may mean that those contacts have some spare time. Located as the
third option in the drop down "News" menu, "Signals" lets you see your contacts'
activity in real-time. Check it out every now and then to get a sense of how people are
using LinkedIn and to understand who might be free for a quick catch-up.
Tags
Tags are another lesser known feature that allows you to organize your
connections however you see fit. LinkedIn automatically organizes your
contacts based on company, location, industry, recent activity, and your
relationship with that person. Additionally, you're also able to create new tags
so that you can organize your contacts as you wish.
Get Introduced"
LinkedIn's "Get introduced" feature, located on the drop down to the right of
'Connect', allows you to send a message to one of your current contacts that is
connected with the targeted professional. Yet, be sure to know that mutual
connection well and clearly state sound reasons why you'd like your contact to
put his reputation at stake to introduce you to one of his connections.
NOTE: If you have a basic account (the free one), you're limited to 5
introductions. So, if that relates to you, choose your battles wisely.
Personalizing Messages When Connecting
Most of the connections people receive include the stock LinkedIn message
attached. I don't have proof to back that fact up, but I'd be willing to bet it's true.
When you personalize a message, you're creating a more memorable connection
between yourself and the professional you're trying to add as a contact.
