▪Robustnessmeasures the program’s capability towithstand abnormal conditions.
▪Efficiencymeasures the program’s capabilty to usecomputational resources in an economical and rational way(time and space).
▪Usabilityeasiness to use and learn as perceived by theusers.
▪Costdevelopment time, human resources.
