How does the incremental delivery approach conflict with the procurement model of many organisations?
Correct Answer
In the incremental approach, there is no complete system specification until the final increment is specified, but many organisations' procurement models require the complete system specification as part of the development contract
Explanation
The iterative nature of incremental delivery means the specification is developed alongside the software — there is no complete system specification until the final increment. This conflicts with many organisations' procurement models, where the complete system specification is part of the development contract. Large customers such as government agencies may find this difficult to accommodate.
