Based on the typical phases of website development, the correct order for the tasks would be:
1. Randolph and his team interview a client to find out the requirements for the client's website.
2. The team creates a sitemap based on the gathered information.
3. The team creates a flowchart and wireframe based on a webbed storyboard.
4. The team uses a coded approach (HTML, CSS, and JavaScript) to create the required web pages.
5. The team checks the website against worst-case scenarios and for potential bugs.
6. After client approval, Randolph and his team launch the website on the client platform.
7. Randolph delegates monthly update tasks to two team members.
