Testing code at random places in random ways is hardly efficient , and while it might work with huge numbers in a three dimensional environment in the body , it is not likely to be a useful idea in the one-dimensional world of computer memory . Modeling permits analysis of the variables involved ( time , numbers of patients , resources available , etc. ) in quantitative terms so that planners can work with concrete numbers as they develop and modify their strategies . As your own and your competitors ' AdRanks change , the AdWords discounter will work with new numbers . There are arguments for both stances : we do n't have time / space / resources to wait - we can work with X number of people now . We will work with rational numbers and activities dealing with ratio , proportions , and that big stumbling block , equivalent fractions .
