In a single-subject study of a software developer working in an object-oriented programming environment, we found evidence of a development style characterized by pervasive software reuse. The subject employed regular strategies for template selection and coding in her work, and avoided techniques requiring deep understanding of code details or symbolic execution whenever possible. Within the limits of the design of the study, the subject's performance is related to attributes of object-oriented programming and our interpretation of the mature mental model with which she approached her task.
