If, then, our analytic goal is to set in motion a process that leads to good hours, how do we go about achieving this goal? Our approach will be through heuristic strategies. When I speak of strategies I refer to plans that guide activity toward some goal and are implemented by specific procedures. Strategies are used in all walks of life, although we may not be aware that we are using them. Specifying strategies is useful for teaching; we can present the strategies that have served us best for any given purpose. More important, specifying strategies is scientifically useful in that specification can help us understand exactly what we are doing. If desired goals are not attained, the problem may lie in the use of faulty strategies.
