Sure Step Methodology - Best Practice

Hello Guys,

I would like to discuss some best practices regarding the sure step methodology:

1. In which phase (Analysis, Design, or Development), we should start CRM configuration (Customization of entities and fields)?
2. Are the entities needed to meet the business requirements defined in the Analysis or Design phase?
3. If we want to build a small team to work on a CRM Enterprise project instead of a team with 7 or 8 roles, can we have a team composed by the following:

            a. "Business Analyst" for the Analysis phase who has a minimum knowledge in the technicality of Dynamics CRM and can gather the requirements and document them

            b. "X" who has a very good knowledge in the technicality of CRM and can read the requirements and prepare the design with the detailed development tasks

            c. Application developer to do the development
