Final answer:
Big data from the National Change of Address database improves organizational efficiency by providing accurate addresses for better administration, reduced mailing costs, and insights into demographic trends for strategic planning.
Step-by-step explanation:
Accessing big data from the National Change of Address database significantly improves an organisation's efficiency by ensuring up-to-date and accurate address information. This leads to reductions in administration costs, due to fewer instances of 'return-to-sender' incidents, and optimized mail delivery processes. Additionally, having accurate addresses helps organizations understand demographic trends, such as population growth or decline, which is valuable for strategic planning.
By matching their customer databases with the National Change of Address data, organizations can purge outdated addresses and maintain a cleaner database. This streamlining results in improved customer service and can also contribute to more efficient marketing campaigns by ensuring that communications reach the intended recipients. The big data analysis ensures that the data used is characterized by Volume, Velocity, Variety, Veracity, and Value - the five Vs of big data.
