TCS Salary Hike April 2012 – An Estimate

This study has been prepared on the famous Newton’s Algorithm - Newton–Raphson Method along with Linear Interpolation, Current IT Market Scenario and Macro Level Challenges which IT Companies normally suffer with.

The study takes into consideration that most of us would be placed in Band B or Band C. As, people hardly get Band A in TCS with 3 Years Experience. The study fails for Band D because TCS has an unusual process of decreasing the salary rather than increasing it. So by means if you happen to have a Band D (unfortunately) your experience would have increased with a negative hike in salary. It’s weird but TRUE.

The graphs and tables below show a comparative study of estimated salary hike in April 2012 across different TCS Bands for people having 3 Years Experience:

Ø Moving from Band B to Band B

Description	Salary (Lakhs)	Band	%Hike
Joined TCS	3.15	C	7.93
Hike After Recession	3.40	C	17.64
Apr’10	4.00	B	18
Apr’11	4.72	B	13
Apr’12	5.33

The analysis found that there would be an estimated salary %Hike of around 13% with final salary falling around 5.33 Lpa.

Ø Moving from Band C to Band C

Description	Salary (Lakhs)	Band	%Hike
Joined TCS	3.15	C	7.93
Hike After Recession	3.40	C	17.64
Apr’10	4.00	C	8.75
Apr’11	4.35	C	11.44
Apr’12	4.84

The analysis found that there would be an estimated salary %Hike of around 11.44% with final salary falling around 4.84 Lpa.

And finally the Blockbuster:

Ø Moving from Band C to Band B

Description	Salary (Lakhs)	Band	%Hike
Joined TCS	3.15	C	7.93
Hike After Recession	3.40	C	17.64
Apr’10	4.00	C	8.75
Apr’11	4.35	C	22.52
Apr’12	5.33

A whooping estimated salary %Hike of around 22.52% with final salary falling around 5.33 Lpa. Even the graph has Skyrocketed.

Please note this is a salary estimate and has to be kept in the bracket of ± 2% Deviation. So if you happen to get a salary hike in TCS more than the ones which are mentioned above than that’s Great!! What needs to be seen is Can an Organization with 2.4 Lakhs (as on Q2-11) Workforce keep its Employees Happy??

If by any means the salary hike is less than what is mentioned above then start preparing your resumes, get those posted on job portals or get yourselves a reference for a company because you are not getting the correct price of the invaluable talent you carry.

In the end, I happen to remember the Royal Stag tagline It's Your Life Make It Large.

Please feel free to drop in your valuable comments. The highly anticipated post Realizing Your Potential While Experiencing Uncertainty would be out soon.

Online Shopping Portal -Case Study -Solutions

After learning all the technologies within the first 4 weeks, participants are expected to develop the below given casestudy in week 5.

Scenario: Online Shopping Portal

XYZ.com wants to create an online shopping portal for managing its registered customers and their shopping.

The customers need to register themselves first before they do shopping using the shopping portal. However, everyone, whether registered or not, can view the various products along with the prices listed in the portal.

The registered customers, after logging in, are allowed to place order for one or more products from the products listed in the portal. Once the order is placed, the customer gets a reference order number and the order status should be “order in process”.

The customers can track their order using the given reference number.

The management of XYZ.com should be able to modify the order status of a particular reference order number to “shipped” once the products are shipped to the shipping address entered by the customer at the time of placing the order.

Can you help XYZ.com to realize their dream of having an online shopping portal?

Steps to be followed

1. Create the interface for the XYZ.com shopping portal using HTML/XHTML and CSS.
2. Implement the client side validations using JavaScript.
3. Create the tables using MySQL.
4. Implement the functionality using the server side scripting language, PHP.
5. Integrate all the above tasks and make the XYZ.com shopping portal functional.

Note: Please zip your casestudy files and upload it here. You can submit only one file.
