Changes to Services The Parties acknowledge and agree that there will be changes to the scope of the Services during the Contract Period. The Customer may amend the Stories that are comprised within the Minimum Marketable Features of a Release at any time during the Release at no additional charge and without adopting the Change Control Procedure set out in Clause 28 above provided that: the Customer shall not be entitled to make any changes to the Stories that form the subject of a Sprint following the mutual agreement by the Parties of the Sprint Plan for that Sprint; new Stories and/or changes to existing Stories may only be introduced if: existing Stories with an equivalent number of Story Points are removed; or existing Stories are reduced in size by the equivalent number of Story Points, such that the total number of Story Points for the Release remains constant throughout the Release. The Supplier shall consider any request by the Customer to increase the number of Story Points for a Release, and may, subject to the Change Control Procedure set out at Clause 28, agree to such request.
