A client that you have developed a close relationship with has asked you for ad

A client that you have developed a close relationship with has asked you for additional services that are outside of the scope of the project.  You don’t want to say no because it might damage the relationship.  But you don’t want to say yes and now run the risk of derailing your project.  Your sponsor explains that while you can’t go out of scope, you do have the ability to continue the project and then create a new contract for the additional services.  Think about what type of contract you feel would be best based on the relationship and the situation you are in.  Also, consider metrics you should include (you have flexibility.  just explain your reasoning).  Use the reading for this week to help you.  Think about what you would do and then write a professional business letterLinks to an external site. to the client and attach it to your discussion response in Word document format (NOT Pdf).  Make sure you provide a sufficient amount of detail based on what you have learned in this week’s reading and other readings during the semester.
