Rookie Ratio is defined as number of people with less than 2 years employment. Recently employed people are less stable than old. They are also less efficient, because they have not yet socialized into the tradition of the organization, so they do not know the most efficient way around.
Formula (Headcount.0_to_2_years / Headcount )
It is important to recognise that there is no ‘perfect’ level of rookies in an organisation. Too many and too few can both be problems. The real focus has to be on identifying particularly high or low levels, the reasons for this and the implications for the business.
Typically, ‘rookie’ employees can be less efficient in the immediate term than those employees who have been with the company for a while as:
• they are still learning the organisation’s systems and processes;
• they place greater demands on the HR team.
In fact for many, getting rookies to stay is an integral part of the resourcing lifecycle.
Nevertheless, they bring significant benefits and their presence is often used as part of overall ‘organisational health’ assessments. In particular, organisations with a low turnover of staff can suffer from limited levels of experimentation and innovation.
A flow of new recruits provides new ideas, impetus to challenge existing ways of working and ensures a supply of new talent entering the management structure. The challenge for businesses is to find the optimal balance between fresh ideas and retaining existing organizational knowledge.
