资料：Workforce planning helps an organization to estimate its future workforce requirements and calculate the numbers, nature and sources of potential employees who might meet that demand.
Effective workforce planning helps companies identify and plan how to tackle their current and future workforce challenges and priorities. It provides a sound basis for developing an effective workforce strategy.
An easy way of thinking about workforce planning it to get the right number of people, with the right skills, in the right place, at the right time. For our company, the right people will be those with relevant skills and capabilities to drive the company forward this year, next year and future years. Our company then provides training and development opportunities that enable people to enhance their skill sets and build their careers. This gives the company the continued benefit of experienced,committed and well-trained employees.
Like other established companies,we may have a large number of long-standing employees with vast skills and experience. However, as people retire, it needs to replace those skills. Careful monitoring is essential to examine the age and skills profile of the workforce when compared with present and future company needs. This ensures the business can meet its objective.
