Background Material


Different authors look at the problem-solving model in varying ways.

Murdach (2007) suggests the principal stages of Perlman’s problem-solving model are simply:

  • problem definition,

  • problem analysis (including the generation and review of alternatives), and

  • the need for specific decision about a course of action (including methods of monitoring and evaluating the results of such action).

Chenowith and Lehmann (2008) describe a planned change process model:

Chenowith and Lehman also suggest the model outlined in the Practice Approach that follows. It consists of four phases:

  1. The engagement phase involves making contact, exploring needs and setting preliminary goals.

  2. The assessment phase involves collecting information, prioritising issues and agreeing on action.

  3. The intervention phase involves implementing and modifying strategies to achieve goals.

  4. The evaluation phase involves reviewing what has happened, celebrating progress and either concluding the work or negotiating a continued relationship.
