To build on what I said, the above is only really relevant to the recruiting arm of HR.
You MUST be precise in your response about which arm of HR you are discussing. I recall seeing performance evaluations and job analysis close to each other in your paragraph - these two strategies relate to different roles!
Eg. if we were looking at the HR role of maintaining, the objective is to retain 'best practice' if applicable, monitor employees' performance, help them to grow and prosper in the company, maintaining their interest/ties to company etc. HR can do this by using strategies such as performance evaluations, annual Christmas parties etc. To explain Christmas parties - you are less likely to 'leave' your job and have a higher sense of job satisfaction if you are involved in (and invited to) non-work-related events that boost your ties to the company and cement your shared understanding of its culture. It's a hidden method of developing a passion for the company.
