What's Wrong with Agile Methods? Some Principles and Values to Encourage Quantification

Agile software methods (Agile Alliance, 2006) have insufficient focus on quantified performance levels (that is, metrics stating the required qualities, resource savings, and workload capacities) of the software being developed. Specifically, there is often no quantification of the main reasons why a project was funded (that is, metrics stating the required business benefits, such as business advancement, better quality of service, and financial savings). This means projects cannot directly control the delivery of benefits to users and stakeholders. In turn, a consequence of this is that projects cannot really control the corresponding costs of getting the main benefits. AbstrAct
