I have a project where the planned tasks are spread over several weeks, see attached.

How is the summary % complete total calculated? Can I relate to %complete against project days?

The summary % Complete is an average of the children.

Can you explain in more detail what you mean by "Can I relate to %complete against project days"?

Hi Paul,

Thanks for your reply. From my example 44% complete implies 1.10 days completed in the project. However, project days x %complete gives 1.15. Is this correct? Because my project days are spread over a longer durations, what the best way to represent the %complete?

That depends on the level of accuracy you are looking for. the 0.05 days difference relates to 1 hour and 12 minutes difference.

Also... What is the difference between the Project Days and the Duration?

I'm just struggling to figure out exactly how your process is working.

Hi Paul,

Project days are the days sold to the client for the delivery of a task. However, this may be spread over weeks which gives a longer duration in smartsheet, e.g. 18/08/19 to 28/08/19 gives 9d duration but the time spend on the project is 1 day spread over the 9d.

So could it also be said that the duration is 1 day with 8 days lag or lead time?

Hi Paul, that's correct. However, the nature of our construction projects is that 1 day is schedule over 2 weeks but we not sure when the work would actually be done so the plan shows the duration as 10 days against 1 project day. Regards Steve

You would need to be able to build in actual start and finish dates and run your % Complete off of those then.
