When should the project schedule be developed?

Option-B During initiating. The definite project schedule should be developed concurrently with the project contract (if applicable) and the project charter.

It depends on requirement of contract documents. Usualy milestone time schedule is required during the tender stage. After awarding the contract,  a detailed time schedule (Baseline Program) is submitted within the time limit specified in the contract by the client/management/engineer.

I think the option is :

d- When most planning processes from time, scope, and procurement management have been finished. These will then iterated when necessary.

First, when prices Make Offer Secondly, when the project work plan

Option d- is the most apporopriate answer.

I will prefer option#D ------------------

You can estimate a theoratical time table to give the stakeholders an idea, how long it would take to complete a project like this ... perhaps quoting a similar project ... add a few weeks to the time table ... however let them know that you need to adjust this prodiction when all vital information is gathered ...

Usually this will be at the end of the planning stage and lunching the project 

in my openion, just a day after the launch. Development is an ongoing progress that never ends. 

Thanks for invitation -

My opinion is the choice - D .

Tge develop schedule process is where the schedule is created and uses the define activities, sequence activities, estimate activity resources, and estimate activity duration’s processes as its inputs hence option D is the Answer.

Sure it will be the answer d-When most planning processes from time,scope,and procurement management have been finished. These will then be iterated when necessary. Because you can't develop the schedule with out the deliverables of other departments plans.

To Who's select option B -- word "Definite Schedule" is more details then the required/available information in project initiation stage - at that stage only the project expected or required duration as per stakeholder/sponsor requirement
