14 ;;Quote: need an operational profile to estimate the reliability of software under actual use

14 ;;Quote: the operational profile and quality-improvement techniques reduced problem reports and maintenance costs ten-fold; test interval doubled

15 ;;Quote: an operational profile built from other profiles; i.e., disjoint alternatives with probability of occurrence; use logarithms

16 ;;Quote: operational profile by breaking system down into customer groups, user groups, system modes, functions, and operations

18 ;;Quote: use novice and expert system modes to record changes to an operational profile as users become experienced

19 ;;Quote: determine the functional profile of a system from its work-flow; gives context for software

20 ;;Quote: use environmental variables for conditions that effect the way a program runs; e.g., traffic load; use brainstorming

20+;;Quote: the final function list of an operation profile is all possible combinations of functions and values of environmental variables

22 ;;Quote: generate test cases by selecting operations randomly according to the operational profile and input states randomly with its domain

22+;;Quote: an operation of an operational profile implements a function for a range of input values

24 ;;Quote: must limit operation profiles to several hundred elements; several thousand at most

28 ;;Quote: testing via operational profiles identifies failures, on average, according to their frequency; efficient
