TAT reduction in complaint management process

Recommended Posts


I am planning to implement lean six sigma project to reduce TAT in complaint management but i am bit confused on my data collection part.

Should i collect data to see how many times we have not met the TAT i.e. defectives or should i consider the complete TAT details for the project.

My only question here is

1. Should i go with continuous data or discrete? which one will give me a clear picture of the problem

Yes Anish,as recommended by others, continuous datais better as it can be analyzed in several ways. Also, continuous data can always be converted into discrete if need be. Discrete data, however cannot be converted into continuous.

Best Regards,
