Best practices in recruiting and HR have seen a lot of change over the past ten years. This quick list is a great overview to get you up to speed on what's happened, and what to expect next.  
 
1.Embracing change. 
With the economy, technology, and the internet moving faster than ever, HR is more responsive and nimble than 10 years ago.  It's an exciting time to be in HR!

2.Increased use of contract resources. 
Part of being 'nimble' means having a flexible workforce, and the past 10 years have seen organizations respond by making greater use of contract staff.
 
3.Hiring manager SLAs. 
Recruiting's become more complex in the past 10 years; Service Level Agreements between recruiting and hiring managers have become more important to ensuring success.
 
4.Social media. 
Social media continues to become a crucial factor in the way organizations communicate with employees - and the way employees communicate with them.
 
5. Privacy. 
Thanks to #4, one of the biggest developments in HR in the past ten years is privacy of information, whether of candidates or employees.  And we'll see it continue to be a big issue in the next five years, as social media plays a larger role in the pre-screening process.
 
6. Personal branding. 
The personal brands of organizational leaders have become more important to HR and recruiting; the personal brands of employees and candidates have become more important to the organization.

7. HR is more strategic. 
In an increasingly competitive talent market, HR is becoming more strategic across recruiting, retention and employee engagement.
 
8. More metrics. 
In the past 10 years, HR has done a better job of analyzing recruiting metrics.  Determining the sources of the best candidates and long-term performers is just one way metrics contribute to business success.

9. Employee engagement. 
As Gen Ys - and their commitment to a more positive work/life balance - take a larger role in the workforce, employee engagement has become more important.  Expect to see this increase in the next five years.
 
10. Diversity. 
As the workforce - and most organizations' client bases - become increasingly diverse (especially in major population centers), diversity has become even more important for HR and recruiting.
