Hi,
I have attached a very basic analysis template.
Sheet 1 gives a month-on-month attrition rate along with annual attrition percentage. (No biggie.)
In Sheet 2, enter the information, and then this will give you a broad classification as to why there is attrition.
The real task is to set up a good exit interview which examines all dimensions that caused the employee to choose to leave the job.
So design a good exit interview. If you already have one in place, then analyze each question individually. Ensure that there are a sufficient number of questions pointing towards the relationship with the immediate manager, facilities, benefits, relationship with peers, relationship with other departments, etc.
Analyzing these with the additional comments the ex-employee provides will be helpful in arriving at the root of the problem.
There is also a situation where a particular demographic is likely to contribute to most of your attrition worries. What do I mean? For example, in BPOs, fresh graduates, engineers, and those joining in vacations/drops tend to attrite very early, even before they have returned the cost incurred in training! This may be true for your industry too, so go in for a demographic-wise analysis, i.e., what kind of people are leaving the most.
One of the other challenges faced by HR is sensitizing other departments to attrition. Trust me, people in operations and sales do not understand words like talent, loyalty, retention, and anything else that we choose to explain the importance of retention.
Here's something that will definitely ring their bells:
Present a "Cost of Attrition Analysis."
I don't have that handy right now but will post that soon.
