Step 15: Develop functional components
All the functional components identified in the Project Scope Document need to be developed and transparently integrated with the CMS. Regardless of development approach, hosting environment and scripting language, the look and feel of the site should be consistent across all functional areas. This is because the users for whom you are building the intranet site should not ever notice the technology that powers it.
If the site is based on a hybrid development approach, attempt to have all components use the same dynamic templating system. If that's not possible due to incompatibilities in scripting format, at least use the same HTML template and make absolute references to common images, CSS and JavaScript files.
When development is done, ask the developers to properly comment their code. This means that they should review and insert lines of text into their code that explain their rationale for approaching various sections of logic the way they did. This will make updating the code much more efficient in the future because less time will be required for other developers to learn how the code works.
