What does attrition mean?
Attrition is the share of employees who left a company over a period. Indian IT services firms usually report it over the last twelve months, or LTM.
Why do IT services companies report it?
An IT services firm sells the time and skills of its people. On Cityfort's Infosys, TCS and Saksoft pages, staff pay is the biggest cost in "Where ₹100 goes".
When people leave, the company pays to hire and train replacements, and projects can slow. CARE Ratings names attrition and wage inflation among the challenges for IT firms like Saksoft.[S3]
Why do companies' attrition numbers differ in meaning?
Each company chooses what to count. Infosys reports voluntary attrition, which counts only staff who chose to leave.[S1]
TCS reports the share of its IT services staff who left over the previous 12 months.[S2] Read the footnote before comparing two figures.
