This handbook, which presents a design-based approach to training, leads training professionals through a process for developing employee training programs based on a behavioral digital approach. (The design approach is a scientific methodology built on three principles: the systematization, behaviorism, and quantification of training.) The handbook is organized in three parts: (1) Professional Needs Assessment for Renewal/Training; (2) Designing the Training Program; and (3) Designing Program Dissemination and Evaluation. The four chapters contained in part 1 cover the following topics: the reformation design of training, professional needs assessment of a job, professional needs assessment of an organization and its employees, and unifying professional needs and establishing behavioral digital bases of training design. The three chapters of part 2 discuss the design of the training curriculum (goals, knowledge and achievement activities), designing the instruction of training (methods, media, and technologies), and the design of human and material services. The topics of the two chapters of the final part are: designing the training document, program marketing, and preparation for implementation; and designing the evaluation of training. The handbook includes 49 references and an index. (KC)
