The proficient performer perceives situations as wholes rather than in terms of chopped up parts or aspects, and performance is guided by maxims. Proficient nurses understand a situation as a whole because they perceive its meaning in terms of long-term goals. The proficient nurse learns from experience what typical events to expect in a given situation and how plans need to be modified in response to these events. The proficient nurse can now recognize when the expected normal picture does not materialize. Once one has a deep understanding of the situation overall, however, the maxim provides direction as to what must be taken into account.
Maxims reflect nuances of the situation.
The expert nurse, with an enormous background of experience, now has an intuitive grasp of each situation and zeroes in on the accurate region of the problem without wasteful consideration of a large range of unfruitful, alternative diagnoses and solutions. The expert operates from a deep understanding of the total situation. This is not to say that the expert never uses analytic tools. Highly skilled analytic ability is necessary for those situations with which the nurse has had no previous experience. Analytic tools are also necessary for those times when the expert gets a wrong grasp of the situation and then finds that events and behaviors are not occurring as expected When alternative perspectives are not available to the clinician, the only way out of a wrong grasp of the problem is by using analytic problem solving.
