When I compare the advantages of software developed in-house with those of the leading market products, I mean their main architectural advantages:
1. They are usually component-oriented, encapsulating functionality and allowing components to be added or removed as required. This also supports teamwork.
2. They include caching systems, all based on time expiry.
3. They are highly scalable and configurable.
4. Their design implements the MVC pattern.
5. They manage styling through themes or templates.
