Assessing Expert Systems Impact on Users’ Jobs
研究了影响专家系统对用户工作影响的十个因素，基于IBM的69个专家系统项目数据，发现问题重要性、难度、领域专家质量等六个因素影响最大，为管理者提供建议。
:A comprehensive list of ten major expert systems (ES) related factors likely to affect users’ jobs has been defined, including problem importance, problem difficulty, developer skill, domain expert quality, user characteristics, user satisfaction, shell quality, user involvement, management support, and system usage. Impact on the job has been defined in terms of eleven items dealing with changes in job importance, amount of work, accuracy requirements, skills needed, job appeal, feedback about performance, freedom in how to do the job, opportunity for advancement, job security, relation with peers, and job satisfaction. Data were collected on sixty-nine expert systems developed through IBM’s Corporate Manufacturing Expert Systems Project Center in San Jose, California. The results show that the major variables having the most impact on users’ jobs are problem importance, problem difficulty, domain expert quality, user satisfaction with the ES, shell quality, and user involvement in ES development. Based on the results, recommendations are made for corporate and ES development managers to increase the likelihood that ES will have a desirable impact on users’ jobs.
