Introduction Nutrisystem Inc. (NTRI) is a publicly-traded company listed on the NASDAQ and forms the basis of the organization being studied in this case. NTRI provides various weight management services and products, primarily in Canada and the United States. Weight management programs are online tools, counseling, and pre-packed food programs. Foodstuff that comprises of a twenty-eight-day provision of lunch meals, desserts, morning meals, and suppers that ideally add-on the clients with clean fruit, dairy, vegetables, salad, and low glycemic items are also offered. NutriSystem vends meals that are pre-packed to the participants of weight loss via cell phone and internet alongside the televised system of QVC. Organizations comprise of various units that need coordination to operate effectively. Since society’s tasks are accomplished through the organizations, it is upon the management to properly function to get the work done. However, getting the organizations to operate effectively and efficiently proves to be rather difficult and complex while understanding the individuals’ behaviors seem very challenging. Creating harmony and coordinating the management tasks between an organization’s systems and resources in predicting and cordially controlling the inherent complexities, organizational behaviors, enigmatic nature, paradoxes, and contradictions that are present in an organization thus calls for open system diagnosis. Therefore, this report classifies the key components of the environment, strategy, tasks, a formal system, and key individuals in regards to the desired organizational outputs. The report further examines an organizational strategy along the lines of the organization’s environmental inputs. Ultimately, it scrutinizes the process of transformation, and the way interaction in the organizational setting enables productivity. Congruence model for the organization analysis The congruence model developed by Nadler-Tushman is a more inclusive model that specifies outputs, inputs, and throughputs. The model further assumes that an organization is a dynamic entity and open social system found in larger environments as well as interactions and behaviors occurring between groups, systems, and individuals. In this model, resources are the strategically most vital inputs in an organization while the congruence concept in this model links the needs, goals, demands, objectives, and structures of one component to another. The strength of this model is that it takes into consideration all the factor inputs and outputs while trying to create harmony between the available resources to bring balance in the demand and supply (Nadler & Tushman, 1980). However, by analyzing the congruence between an organization’s system parts, much consideration must be given to the system outputs and the paired fits. Hence, fits and deficiency in fits are related to the behaviors eminent in any system such as performance, stress, and conflicts. The comprehensive congruence yearns to specify and interconnect throughputs, outputs, and inputs. The strength of this model is that it incorporates the open systems theory, and retains both the informal and formal systems commonly found in Weisbord’s
