Dear Swati,
Technology and the organisation's culture impact not just HR but all other functions too. The impact is not in isolation to a particular department.
Technology plays a vital role in managing communication within and outside the organisation. When there is a free flow of information, it reduces the time spent waiting.
Technology also plays a vital role in improving the records within the company. When the information is processed automatically, it helps to build dashboards without time in doing so.
Thanks,
Dinesh Divekar
