Haresh,

You maybe searching a wrong topic. Try good scheduling practice or basic scheduling... etc.



Link below is Proper use of Milestone and Constrain

Scheduling Best Practice



In addition P3.x constrain equivalent to P6

P3 3.x Constraint Type:  ------------ P6 PM Constraint Type:

Early Start (start no earlier than) --  Start On or After

Late Start (start no later than)  ------ Start On or Before

Early Finish (finish no earlier than) - Finish On or After

Late Finish (finish no later than) ----- Finish On or Before

Start On ---------------------------------- Start On

Expected Finish ------------------------- Expected Finish Date

Mandatory Start ------------------------ Mandatory Start

Mandatory Finish ----------------------- Mandatory Finish

Zero Total Float ------------------------- Not Converted

Zero Free Float -------------------------- As Late As Possible



PMI has a book of Practice Standard for Scheduling which is a good reference link below.

PS Scheduling.



If you are a member of PMI you will have a free access to all ebook that PMI have and you find a lot of good reading materials about Project Management.

Rodel,



There are lots of book / materials available, if we search on internet, but there are fewer info available for all constraints, which we use in P6. i have studied the link what u have sent to me, that is helping me to some extent....



Can u send me some more useful links, with examples , in what external dependencies , we use constraints….Since I have to prepare for a presentation on this topic , I request you to provide this info….

Thanks in advance

Hi Haresh



The only constraint you should use is on the 1st task which should be start on or after.



All other uses distort the critical path.



Best regards
