Your comments helped me to understand more about TNA.
Mr. Rajan, for your reference, here is a basic overview of some systematic approaches to training:
The following manuals outline systematic training processes. A systems approach ensures a comprehensive training process that remains focused on the needs of the organization. The process typically includes the phases:
1. Analyze the organization's needs and identify training goals which, when reached, will equip learners with knowledge and skills to meet the organization's needs. Usually, this phase also includes identifying when training should occur and who should attend as learners.
2. Design a training system that learners and trainers can implement to meet the learning goals; typically includes identifying learning objectives (which culminate in reaching the learning goals), needed facilities, necessary funding, course content, lessons, and sequence of lessons.
3. Develop a training "package" of resources and materials, including, for example, developing audio-visuals, graphics, manuals, etc.
4. Implement the training package, including delivering the training, providing group feedback, clarifying training materials, administering tests, and conducting the final evaluation. This phase can include administrative activities such as copying, scheduling facilities, taking attendance data, billing learners, etc.
5. Evaluate training, including before, during, and after the implementation of training.
In a systematic approach to training, each phase of the process produces results needed by the next phase. For example, the training analysis phase produces learning goals that are used by the next phase, training design. Training design (often called instructional design) references the goals to design methods and materials from which learners can reach the goals and objectives. Typically, each phase provides ongoing evaluation feedback to other phases in order to improve the overall systems process.
