When the policy is not heading in the desired direction, you can intervene more quickly. It is possible to look ahead, predict and make recommendations. You can also use data that are available from outside of the organisation, even the user generated data. This means you are making decisions based on bigger and various amounts of data.
By connecting large amounts of data, Big Data provide correlations. This allows you to learn from data as well as seeing real-time results. With possibly a positive effect on decision-making. You can also monitor and control performances. With better analysis you optimise the business operations.
