### Cycle Time Spectra Graph?

Hello everyone,

Can you please tell me how to read Cycle time spectra graph for questions where we have to read the graph and see how team is doing?

Best Regards

Hi Seema,

Can you please explain the below line mentioned in the post link that you shared -

So if PM has most of tasks in center which means most of tasks are taking almost same cycle time then the process is under control, ( of course there will always be few tasks which take more or less then mean time) if the cycle time is spread across different time group/days group then process is not in control and predictability is low.

This is very self explanatory not sure how to break it down further.

As mentioned earlier Spectral Analysis graph are used for predictability and planing purposes. X axis has the cycle time taken to complete tasks.

If you have tasks spread across X axis it means that different tasks are taking different time to complete (the spectrum is wider) which is not a healthy situation for the PM as project cannot predict the time it will need/take to complete remaining tasks.
