How does Data Analytics help in Process Management?

Since you are asking specifically about "process management", then .. Data Analytics is expected to improve the performance of the process in terms of efficiency and effectiveness including cuttin down on waste and losses in every aspect associated with the process 

Thank you Thiab, meanwhile can you give me some instance where we come across cutting down on waste and losses.... do you mean we use the methodology to reduce the watages or losses... eg: LEAN...?
