Sorry for delay, As I was busy in work. Let me give a try to give more clear picture what my task is more about
the As-is is done .Project brief as it say that all students write exams all over the world for may  and Nov session its about
marking scripts, storage, award grading(which includes concepts like standardization, moderation, etc)
our project is about computerizing it as papers will be scanned and marked online(e-marking), similarly they want to introduce,
e-checking (inplace of clerical checking) e-assessment(for grade wards) etc

so we got some 3rd party who are doing allthis (but at intial stage not finilized)
so rampup plan is upto 2015 its a big project so introducing this project is not some which is replaced but is done both online
and conventional way so my task is to understand as-is and preapre transition plan(its about rollout and support needs)
which says how much can we target for 2009, 2010..till 2015 for each project and provide information like training needs,
user support needs, which countries we can target ..itsmore about numbers and
and what if we cannot reach our target numbers so i have to document in transition plan.

Hope you got an idea what I am tring to explain where To-be is some thing not done yet bcoz its not decided how can we put the
technology to develop our self or give to others or they have done trails they are happy and they want to impliment.
so I aM trying to understand as-is in more detail so please guide hoe can I make things much better
and how should I approach to make transition plan , like assumptions, constraints, other factors how should I document
As I am gathering information and I need to represent statistically or a way ..which I need to find.

Thank you ,

Srikanth.

Srikanth,

My suggested headings for things that need to be done as part of the transition plan based on POLDAT (some of these may not be relevant of course - depends on your project scope):

Processes - how will processes migrate from old to new and how will the business function during the transition (e.g. special interim processes and procedures?).

Organsiation - how will the organisation migrate from old to new and how will the business function during the transition (e.g. special interim organisational structure?).

Location - how will the business migrate from old to new locations or the changes to the physical structure of the location(s) and how will the business function during the transition (e.g. some locations/parts of locations in use or out of use or changed use? Car parking always a biggie for this one).

Data - how will processes migrate data from old to new and how will the business function during the transition (closely linked to changes to processes as processes manipulate data).

Application - how will processes migrate from old to new applications and how will the business function during the transition (e.g. special interim applications needed?).

Technology - how will processes migrate from old technology to new and how will the business function during the transition (by technology I am refering to enabling technology that allows applications and people to work - e.g. networks and mobile phones etc.).

Customers - if customers are being impacted by the change, the communication plan to inform them and prepare them.

Employees - if employees are being impacted by the change, the communication and training plan to inform them and prepare them.

I bet I have missed stuff, but its a start...?
