Because the code is going to be read by any member of the greater team we need standards.
Then we read the syntax and hence understand the semantics. We need standards to describe the FACE and then the pre- and post-assertions. We need naming conventions. We need comment conventions. We need agreement on how we handle exceptions. Finally we need conventions on how to document the code as we go in a form that will allow a documentor to extract a precise description of the functionality even if in a form that needs re-writing.
Coding Standards for Delphi are available from Borland.
