weekends and holidays, counts towards the lead time. So,
place your order on July 1 and
understand that July 4 is a holiday and Saturdays and
Sundays aren't business days, expect your service to be
complete by August 14.
Working Days: For some services,
specific supplier employees are assigned to specific tasks.
Working days include only those days that those people actually
work on your project. If an individual works on another
customer's project on a certain day, that day will not be deemed
a working day nor count towards your lead time.
So, if you place
your order on July 1 and the individual works on your project
every other business day, expect your service
to be complete in late September.
Wouldn't it be easy for you and your internal customer to
be disappointed if by "30 days" your supplier meant 30
working days and you were expecting the service to be
performed in 30 calendar days? When purchasing services,
personally reach agreement with your supplier on the
meaning of days. And
then confirm it in writing!
