Hi Siva,
     Very first activity is Proof of concept (POC), here we have to show How BW works for clients Reporting requirement during POC we as BW consultants need to creat some sample BW back end objects and also some reports based on business requirement. This is very crucial stage as Client Judge wethere BW would meet his demands. If every thing is fine then next step is Bidding.
After Bidding the contract then actual Project intiates. from here we follow ASAP methodology.
<u><b>
Project Preparation</b></u>
Here Senior Consultant would go to Client place for Business Process Transistion and to know in what way the Architectue should be set up so here Basis People will come into picture.
<u><b>Blue Print</b></u>
Transistion could be understood by BRD (Business Requirement Documents) BRD states what is exact requirement and it is given by End users.
           By seeeing thr BRD's we as BW consultants must prepare APPlication Design Documents . The Application Design Documents states all the Technical aspects that needs to be performed as BW backend and also as well as Frontend.
<u><b>Realization Phase</b></u>
  Here as BW consultants we must start confuguring as mentioned in ADD's by taking care of all performance aspects, once all the configuration are done we do Unit testing. unit testing is an activity where we check all the design process wether it running correct or not. After unit testing we move the design objects to Qulaity for Integration Testing.
<u><b>Testing</b></u>
    Here end user will check all the objects, reports on end to end basis. after integration testing is done then UAT ( User acceptance Testing) would come into picture where user check each process and sign off.
<u><b>Go live</b></u>
Here all the object will be moved to Production where end users and power users can start working on the system. intially for some days Development team would be taking care of all support activites there after  it will be transitoned to support team.
Hope It helps you.
