How We Did It

This is the 14th edition of the annual Business Today 'The Best Companies to Work for in India' survey. The survey is anchored by our knowledge partner PeopleStrong. The data is sourced from our survey partner Naukri.com.
The basic purpose of the survey is to understand the perceptions and aspirations of India's employees across industries, and map these against what they see in their companies, sectors and even across sectors. The key differentiator for BT's survey, compared to some other surveys of this nature, is that it is a web-based survey open to all salaried employees, anywhere in India, in any company, any sector. The survey does not take into account any company data, including HR metrics. The idea is to put forward how the employee community rates different companies as employers, across a set of specific parameters.
This year's survey was carried out between September 28, 2015 and December 18, 2015. Naukri.com divided its active database into different slices based on age, experience, salary levels, etc. Targeted questionnaires were sent to four million respondents registered with Naukri. In all, 13,000 people came to the survey page.
PeopleStrong's team then thoroughly scrutinised the entries. After the scrutiny, we got a final reportable sample of 5,143 respondents, of which back-checks and verifications were done of about 10 per cent.
The Ranking Process
Respondents are asked to rank companies - across industries first, then within their own industry - across these parameters:
Growth oriented - career and growth prospects
Compensation and benefits
Learning opportunity
Workplace diversity initiatives (child care, women safety)
Work-life balance & flexibility
Ethics - Standards of fairness, objectivity and transparency
Stability - Scale and diversity of operations
Other HR practices (recognition, workplace atmosphere, administrative facilities and other perks)
The overall and sectoral rankings are computed separately, but using the same methodology. Overall rankings are based on how respondents across sectors rate companies, whereas sector rankings are computed only from the ratings given by respondents within each sector.
Rank 1 has higher weight as compared to rank 2, and so on. This difference is implemented by using the 90 per cent rule, wherein rank 2 gets 90 per cent of the weight as rank 1, and rank 3 gets 90 per cent of the weight given to rank 2, etc. Once rank scores are computed, the top-ranked company is given an index score of 100 and the scores obtained by the other companies are indexed to the score of the top-ranked company.
