In this final chapter, we looked at how to build a custom application. We looked at how to create a new custom application and the different starting points available. The end-to-end development of a custom application was looked into, including the use of studio. We finished by delving into how to test and deploy a custom application once development is complete.

Through this chapter, we have also seen how to take an example user access application through all of the stages of creating a custom application. From creation to development and then to testing, we finally created an update set containing our application for deployment on other ServiceNow instances.

Building a custom application is a great learning experience and a fantastic way to practice the techniques we have covered in this book. I hope that you enjoy being creative and creating some custom applications of your own.
