Option #2: Diagnostic Model in Action Leaders and managers use diagnostic models to understand the magnitude of change and the processes and systems that may be impacted. After a diagnostic model is used to assess the magnitude of change and how the organization will be impacted, change strategies can then be determined. An analogy can be made to the diagnosis of an illness. Think about the patient who comes to the doctor with a sore throat. The doctor runs a battery of tests indicating that a streptococcus infection exists, for example. The diagnosis has been made and a strong antibiotic is prescribed. Similarly, managers may use a diagnostic model as a doctor uses teststo make a diagnosis and select strategies accordingly. Select a diagnostic model identified in the Module 4 lecture or a model of your choice. Write an essay describing a professional situation in which you saw this diagnostic model used. In your essay: Identify the model Describe the components of the model and their relationship to each other. Assesses whether the diagnostic model you chose is appropriate for all or any of the types of changes discussed in Module 3. The length and formatting requirements are as follows: Your paper must be 3 to 4 pages in length, excluding the cover and references pages.
