Do you think documenting Assumptions is important as part of Project Planning? Where do you document your assumptions?

Yes I do think. Its better to document assumptions with scope statement.

Sure it is important to document assumptions.

I agree with Mr. Mohammad Aslam,  It is better to document assumptions with scope statement.

Assumptions  is very important when we planning to the projects

the most assumptions we can manage them with risk management, scope statement, cost analysis and time schedule When we make projects planning. 

For Sure as An Assumptions Document is simply a collection of all key information, stored in one document, and submitted for approval so without it we cant achive goals 

Yes assumptions are very important, without assumptions we cannot find out the right pathways for a work. 

If we go for a assumption than only we can brain strom about the possible results and the most important example I would like to mention is that ALL THE SPACE PROGRAMES ARE BASED ON ASSUMPTIONS of previous experiences.

Assumtions management is part of risk management and it must be documented to make the required qualitative and quantitative analysis for them.

YES THATS TRUE SIR...........

Yes because Assumptions and constraints show up frequently on our projects. Successful project managers and business analysts keep an eye out for the assumptions and constraints present on their projects.  After all, they can impact your project across a number of variables, including your project requirements and your resulting solution.  Giving the risks that assumptions and constraints can add to your project, I think it’s worth taking a closer look at what they are and how we should identify and manage them.

Assumptions are made at all stages of Project Planning like :

 -  Estimation for determining the Schedule & Cost.

 -  Identification of Risks & Risk Response strategies

 -  Contingencies to be taken into account to arrive at the Budget.

As Project Plans are always documented, it is also required to document the basis, source of data, assumptions etc. and the logical reasoning for calculating the Project Baselines like Scope, Time, Cost etc. 

YES

IT,S TRUE

In project management assumption are value able during planning, estimation and risk register preparation.  It is important to record all the possible assumptions of failure and success to control and act accordingly as planned.
