1. the entire IT outsourcing industry is ~$150 billion large and employs ~3.9 million people.
2. the top 7 largest IT companies employ ~1.3 million people
3. I cannot calculate the exact revenue of the top 7 companies because they are part of larger groups (e.g.: TCS, Wipro). But the Top IT companies headcount and revenue
a) Infosys: ~200,000 employees ($10 billion revenue)
b) Wipro: ~180,000 employees ($7.7 billion)
c) TCS: ~390,000 employees ($17.5 billion)
d) Capgemini: ~200,000 employees (I don't know)
e) CTS: ~260,000 employees ($13.5 billion)
f) Tech Mahindra: ~120,000 lakh employees ($4 billion)
Stories like these come around routinely in the April-June timeframe (every year!) around appraisal time. This '56000' number is simply a random quote 5% of the entire workforce of the top 7 companies. I have seen different media outlets report the numbers as 28,000 this year to 200,000 in 3 years. Honestly, they don't know nor do I.
FWIW, I run an outsourcing testing services firm in India. I am too small to feel market trends. However, I have been reading and talking and interviewing several candidates across India. I can tell you that the tension has been palpable for the last 8 months or so. Many senior folks are feeling a quiet sense of desperation. I don't know if the media sentiment started the tension or if the ground reality is indeed going to force layoffs of senior employees.
