Users like applications that behave consistently and have a standard look and feel. You can achieve this by creating and enforcing site development standards.
It's always a good idea to set some rules for how applications should be developed, regardless of the tool you are using for development. A clear, sensible set of standards that everyone can agree on should be developed before starting any major development. By thinking things through carefully beforehand, you will find that once you create your site standards, you probably never need to change them. Generally, your standards should include details such as change documentation (refer to the section, Separation of responsibilities, change management, and thinking about security, in this chapter), coding standards, naming conventions, screen layouts, and styling (refer to Designing a site-style template in this chapter).
