This Skill Category discusses the special issues and approaches needed to work with vendors
for the development and acquisition of software products. This may range from completely
custom, developed from the customers requirements, to completely off-the-shelf. Regardless of the source of the requirements, there is a need to measure the product against a defined
standard to ensure delivery of the correct product. Performance Based Contracting helps both
the customer and the vendor clearly understand what is expected and how delivery will be
measured.
