First of all, knowledge always pays you back, though not necessarily at once. Somewhere in life, you will find the worth of that knowledge. So, taking a course or certification in any useful subject will eventually pay you back. However, one thing we all should know is that some knowledge demands a heavy investment, like SAP certification. As many of my expert friends have already advised, it is not necessary that we will get a job with a good package immediately. What we all need is patience, which is a virtue.
Second, gaining knowledge at the right time and for the right place is more important. I suggest my friends, before investing in SAP HR Certification, kindly review whether you belong to the HR field first. Second, does your market typically demand SAP in HR, and how many vacancies are available in the market? Maybe your market demands more in Oracle PeopleSoft–HR or may need Microsoft Dynamics in HR certified candidates. A well-done survey of your market is more important if you have the right approach.
