It is always better to keep in touch with the development team after the project completion and obtain their services for all the problems that you face. This is because of the following reasons.

Bugs are any abnormalities in the program. No matter how good a programming team works, bugs are bound to exist. To remove those bugs, bug fixes or service packs are required. Only the development team can provide these bug fixes as they are the ones who developed the original code.

Each developer would follow his or her own logic to develop a code. This would not be easier to understand for other developers. Hence maintenance of the code would be next to impossible unless the original developers are involved in the job.

The business websites would need lots of enhancements to keep up with the changing market! To perform any enhancement or update the original code must be understood. Thus, the developers are best suited for providing enhancements. This also means the cost of developing the enhancements with your original developer is likely to be less!

Since the developers would have been involved in the entire development process, they are bound to have a thorough understanding of your business processes and your requirements.

If you are seeking new teams for managing and maintaining your website, you must spend a lot of time to make them understand your business processes and your requirements. Even if they do understand that, they would find it extremely difficult to see how the original developers devised ways to meet your requirements.

Thus, it is always better to employ the development team for all future maintenance activities!
