Employees in the organization reflect all elements so as to help realize the Business strategy, e.g. skill, attitude, competencies, reward, recognition, satisfaction due to effective promotion policy, desired behaviors to keep the customer satisfied, performance, requisite passion, team spirit, etc. It is all of this that translates into the business numbers of productivity, growth and profits. Aligning HR with business strategies makes sense and helps ensure the company can realize goals.  With HR at the planning table, HR can forecast how many people will be needed and with what skills. 

With the world changing every moment with new technologies and newer possibilities the company that manages change best will most likely best its competitors. The HR staff should train the company workforce to figure out how to capitalize on a changing business environment and train company leaders to embrace the opportunities change can bring. Thus an alignment between the two has become a necessity.
