This paper describes a multistrategy knowledge-based framework for supporting human experts in assessing applications for the house renovation grant system (HRGS). This framework integrates different problem solving strategies as set up by the task analysis. The task analysis carried out in the context of the HRGS domain decomposed the overall task into a number of subtasks and problem solving methods for performing each subtask. The framework modularises the knowledge required to solve each subtask into historical cases, objects, procedures and domain models. The framework was implemented as a computer system using Kappa-PC which is a shell designed for implementing knowledge-based systems. The implementation followed the client centred approach (CCA) method. This computer application has been successful in demonstrating that a multistrategy knowledge base can be used to support human experts in assessing applications for the HRGS. Therefore, the application has proved to perform as accurately as human experts do for all of the subtasks set up by the task analysis.
