Final answer:
The Dedicated HR model is the structure that may lead to duplications and inefficiencies due to each department having its own HR personnel, causing overlapping efforts and inconsistencies. In contrast, Functional and Shared Services HR models centralize functions to reduce duplication and promote uniformity.
Step-by-step explanation:
The HR structure that may lead to duplications and inefficiencies is the Dedicated HR model. In a Dedicated HR structure, each department or business unit has its own HR personnel who handle only the HR needs of that particular unit. While this can have the benefit of specialized service tailored to the specific needs of the unit, it can also result in duplication of effort across the organization as multiple HR units may be carrying out the same tasks independently. This lack of centralized coordination can lead to inefficiencies as well as inconsistencies in HR policies and practices.
A Functional HR model, on the other hand, centralizes HR functions and specialists are responsible for specific HR tasks across the whole organization, reducing duplication and promoting a more uniform approach to HR management. Lastly, a Shared Services HR model aims to combine the benefits of both the dedicated and functional models, allowing for specialized and high-volume HR services to be provided efficiently to various departments from a centralized team.
Although these HR structures may be more suited to particular organization sizes or types, it's critical to ensure that the chosen HR model aligns with the company's strategy and goals to minimize inefficiencies and duplication.
